Choosing PowerPoint slide size is a key part of your presentation setup. It ensures that your content looks its best in the way that you want to share it. 

You might present PowerPoint presentations on a variety of screens, such as:

  • laptop screens
  • conference room projectors
  • iPads and tablets
  • widescreen, large format displays

Each of these displays has a different shape or aspect ratio. The aspect ratio is a measure that describes the width versus height of a screen. The same PowerPoint slides will appear differently on each device. That's because the aspect ratio can vary. 

Size for PPT slide

This brings us to the first step. Begin by choosing a size for PPT slide layouts by deciding what device your slides are most likely to appear on. This drives the slide size in PPT that you’ll want to use for best results. 

The specific setting depends on the device you'll use. Here are rules of thumb for which one to choose:

Laptops 16:9 (MacBooks are 16:10)
Projectors 4:3 or 16:9
Large-screen displays 16:9
Tablets 4:3

These aren't the only options, of course. PowerPoint slide size change features like Letter Paper or Ledger Paper are also available. These are meant for printed slides, so that they fit perfectly on different sizes of paper.

The key is to choose the size that works for your audience. It's how to change slide size in PPT in a way that works best for you and your work.

How to Change the Size of Your PowerPoint 

We've learned the basic rules for slide size in PPT. Now, let's put this knowledge to work. Read on to learn how PowerPoint slide size change works. We'll work through it step-by-step. In moments, you'll know how to change slide size in PPT.

1.  How to Change the Size of PowerPoint Slides

You've chosen the screen you'll present on. And you've chosen the right size for your PowerPoint presentation. Now, it's time to change your PowerPoint file to match.

Click on the  Design  tab on PowerPoint's ribbon. The available options will change on the ribbon. Find the  Customize  section on the ribbon and click on the  Slide Size  icon. 

A drop-down menu opens with several options. Click on Custom Slide Size  to open the Slide size menu and change your presentation's dimensions.

The Slide Size  menu opens, and now we can change the PPT slide size using the dropdown options.

It may not always be possible to choose the perfect size for your presentation. If you send and share your presentation, then you can't control the device that your audience will open your presentation on. 

You can optimize the presentation for most viewers. Let’s look at the process for PowerPoint changing slide size.

2. Setting Slide Size in PPT (Quickly and Easily)

Let's see how to PPT change slide size. Start by clicking on the drop-down box under the Slides sized for: option. The slide size in PPT you choose should be based upon the screen it'll appear on.

There are several choices on this drop-down menu. The most common choices that I use are On-screen Show (4:3) , On-screen Show (16:9) , and On-screen Show (16:10).  Think of these as the choices for PPT size of slides.

PowerPoint changing slide size

I use each of these settings often. That's because they match the most common devices PowerPoint presentations are shown on. Refer to our handy table earlier in the tutorial to decide which to use. 

After you select a slide size in PPT, press OK on this menu. PowerPoint will show a new menu that gives you a choice of how to change slide size in PPT. Let's take a closer look at which PPT change slide size option will be right for you.

PowerPoint Slide Settings: "Maximize" Versus "Ensure Fit"

When we size for PPT slides, PowerPoint presents us with two unique options. These are drastically differing options for changing PowerPoint slide size. We already have content on our slide, so it makes sense that we need to think about how to handle changing the slide.

The menu shows two options for PPT change slide size:

  • Ensure Fit 

Choose one of these PPT size of slide options. They've got different approaches for PowerPoint slide size changes.

PPT change slide size

  • Choosing  Maximize zooms in on the slide so that the content fills the slide. The downside to this approach is that some content may be clipped off if you've got elements on the slides' edge.
  • Ensure fit makes sure that everything stays on the slide after you adjust the slide size in PPT. But it might leave horizontal bars above and below your content.

When you use a PowerPoint slide size change, give your presentation a thorough look. This is to make sure the content hasn't been altered after the PPT change slide size.

I typically choose to Maximize Slides . But it might take some re-working of the slides to fit properly. Learning how to change slide size in PPT requires reviewing your deck after this adjustment.

When to Use Special Case Sizes

The Slide Size options window can change your presentation size for practically any situation.

Imagine that presentation will be viewed on a portrait orientation device. Portrait orientation implies that a screen is taller than it's wide. Maybe the viewer is viewing it on a tablet in portrait mode, or on a monitor that's rotated in portrait mode.

PowerPoint slide size change

To change a PowerPoint presentation to Portrait orientation, change the  Slides  option to  Portrait  as shown above.

You may not use these options often but remember that they exist. PowerPoint truly accommodates. 

3. Remember to Test

The success of a presentation comes down to the preparation behind it. Giving a presentation to an audience is daunting. But doing a " dry run " (practice presentation) reduces surprises.

This is especially key when you've changed PowerPoint slide size.  The PowerPoint slide size may make unexpected adjustments. They're easy to correct, but you can't fix them until you find them! You never want to first see issues in the real production.

Doing a dry run of your presentation will ensure two things: 

  • That you've got all the cables and connections you need to display your presentation. 
  • It's a great time to compare the dimensions of your file to the screen you'll use. That way, you can re-work your slides dimensions as needed. You can also rearrange content in case you find something out of place. 

presentation powerpoint slide size

Don't forget to include testing your PowerPoint file on the display you'll use for your pitch. It's another variable you can control for while preparing. This helps reduce the uncertainty of your presentation.

What if you didn't have to worry about the dimensions of your PowerPoint slide? You know how to change slide size in PPT, but you can avoid the adjustment altogether. Instead of guessing at the PowerPoint slide size , you can use a pre-built template from Envato Elements.

Not only does it feature templates with the perfect PowerPoint slide sizes, but it also does so with excellent designs. Many of the templates contain more than one PowerPoint slide size so that you always have what you need.

What's even better is that Envato Elements helps you keep costs low. That's thanks to an unlimited download model. With one subscription, you unlock  everything.  Not only does that include perfectly sized PowerPoint slides, but stock photos, graphics, and more.

Many Envato Elements PowerPoint slide size templates have many aspect ratios built in. So, you can work with great slide designs at the common sizes you're likely to need for your presentation. They make it even easier to use PPT change size slide options.

Other presentation designs are made at Full HD (16:9) aspect ratio, which is a popular display size. Or they come with extra dimensions supported. Discover more in our curated selection of the best below, and then continue with this tutorial:

No matter your skill level in PowerPoint, it always helps to have a few extra tips. Let's check out five more top tips for PowerPoint slide sizes, including PowerPoint dimensions.

1. Edit the PowerPoint Dimensions First

Earlier in this tutorial, you worked with PowerPoint slide dimensions. But the most important part of doing so is the order of your steps. 

Make sure your first step is  Design > Slide Size.  When you set the size of your PPT as soon as you open the presentation, you won't clip or stretch your slides.

Changing PowerPoint slide size

This is the best way to avoid re-work while working with PowerPoint slide sizes. Set your PowerPoint dimensions first!

2. Use the PowerPoint Rulers

Many presenters (myself included) use PowerPoint to create printed, products too. And the size of your PowerPoint slide  really  matters when you're trying to fit them to a printed page.

That's why it helps to check your PPT slide size with rulers (in inches.) To view them, go to the  View > Ruler  menu option.

How to change slide size in PPT

Of course, you can scale the PowerPoint slide size while you're printing to match the paper. Check out our guide to printing, no matter the size of your PowerPoint slides.

presentation powerpoint slide size

3. Edit the Slide Master

Slide masters control several slide designs at the same time. Instead of setting layouts and PPT dimensions on each slide, consider editing the slide. Set the PPT slide size and dimension on the master on the  View > Slide Master  menu.

Learn more about editing slide masters and presentation slide sizes in the tutorial below:

presentation powerpoint slide size

4. Simulate a Preview

Earlier in this tutorial, I recommended checking your presentation as a rehearsal. Ideally, you check your PowerPoint slide size on the exact display you'll use for the real thing.

Unfortunately, you won't always have the option to rehearse in the presentation room. But you can check it on your computer screen. You can preview your PowerPoint presentation and see how it uses the screen real estate.

Go to the Slide Show > From Beginning menu option to preview your presentation. Then, review if you can see any bars or lines on your screen. 

Check size for PPT slide

Most computer screens are 16:9 or 16:10. If you know your final screen has the same dimensions, this is a good check for PowerPoint dimensions.

5. Use Slide Layouts

You shouldn't have to set the PowerPoint slide size on each slide. You can set the dimensions of your PowerPoint presentation, but the presentation slide size matters too. Set the PowerPoint slide size with layouts that position elements perfectly.

In a template like The X Note , every slide layout carefully considers the size of the PPT. Use a layout for the size of PowerPoint slides on the  Home > Layout menu.

Layout slide size in PPT

Use the Layout  drop-down to select the dimensions of your PowerPoint slide.

Here's an even better way to nail your PowerPoint dimensions . Start with a template. Most PowerPoint templates from Envato Elements have several versions of PowerPoint dimensions.

These are five of the best PowerPoint templates on Elements. Check them out to create a presentation with perfect PowerPoint dimensions:

1. Style Multipurpose PowerPoint Template

Style multipurpose PowerPoint Slide

This template is packaged with two colors and one PowerPoint slide size, but I find it easily adjustable in my testing. It features the 16:9 aspect ratio that's the classic PowerPoint slide size. Use the 100 unique designs, each with perfect PPT slide sizes.

Agio PowerPoint Template

Agio is a clean and minimal PowerPoint template. You'll find that the 16:9 PPT slide sizes are perfect for most screens. Not only are the presentation slide sizes set nicely, but the designs are also simply stunning. Fill out these slide blueprints for a professional presentation.

3. Ever PowerPoint Template

Ever PowerPoint template

When you open this presentation, you'll find two PowerPoint dimension options: 4:3 and 16:9. It's these two PPT size options that give this template extra value. There are beautiful slide designs for both PowerPoint slide sizes. Use the hand-designed infographics for business-friendly illustrations.

4. Sprint PowerPoint Template

Sprint PowerPoint Presentation

Life might be a marathon instead of a sprint but designing a presentation shouldn't be. The aptly named Sprint presentation is a 4:3 design with a bright orange color scheme. Choose this if your PPT slide size should be in the more traditional 4:3 size.

MasMax PowerPoint Slide Template

Rounding out our options, MaxMax is a 16:9 PowerPoint dimension template. With 234 unique slide designs, there are options for practically every design you could need. The size of your PPT is already set and you can use the free icons for a bit of extra flair.

PowerPoint allows you to format and present the content of your slides in different ways. If you want to print out or display your PowerPoint slides in a bigger or smaller-than-average size, you can change the slide sizes to match.

PowerPoint has two common slide sizes. The first, 4:3, is a good option if you're using older hardware to present your slides. If you're planning on presenting your PowerPoint presentation using a modern projector or display, then the 16:9 slide size should be your preferred choice.

By default, PowerPoint will default to the 16:9 side slide. To print your slides (full size, one per page), you'll likely need to use a custom slide size, rather than one of these options.

Switching to another size is thankfully an easy process---open your PowerPoint presentation to begin and then click the "Design" tab on the ribbon bar.

Press the Design tab on the ribbon bar in PowerPoint

In the "Customize" section of the "Design" tab, select the "Slide Size" button. This will display the two common slide sizes in a drop-down menu.

Click either the "Standard (4:3)" or "Widescreen (16:9)" option to switch all of your PowerPoint slides to that size.

Selecting a slide size in PowerPoint

Unfortunately, it isn't possible to use multiple slide sizes in a PowerPoint presentation. Just as if you were making PowerPoint slides vertical , any changes you make to your PowerPoint slide sizes will apply to all slides.

Related: How to Make Slides Vertical in PowerPoint

It's possible to use a custom PowerPoint slide size if the default 4:3 or 16:9 options are unsuitable. You might choose to use a custom slide size if you're printing full-size PowerPoint slides using a custom page layout, for instance.

To do this, select Design > Slide Size > Custom Slide Size to display the "Slide Size" options menu.

To set a custom PowerPoint slide size, press Design > Slide Size > Custom Slide Size.

Various preset slide sizes, such as A3 or A4 paper sizes, are shown under the "Slides Sized For" drop-down menu.

Select one of these preset options, or set your slide dimensions manually using the "Width" and "Height" option boxes. From there, click the "OK" button to save.

If you're scaling down to a smaller size, PowerPoint will ask you how it should handle any slide content.

Choose "Maximize" if you want the slide contents to remain at a similar scale, but with the risk that some of the content may be cut. Alternatively, click "Ensure Fit" to scale the slide contents down in size to match the new slide size without losing any content.

Choose the "Maximize" or "Ensure Fit" option.

Once saved, the custom slide size you selected will be immediately applied to all of your slides, with slide content being resized or cut to match.

How to Change Your PowerPoint Slide Size (16:9 vs. 4:3)

  • PowerPoint Tutorials
  • March 10, 2019

In this tutorial, you’ll learn how to change your slide size in PowerPoint.

That way you can create slides for any situation including on-screen presentations, printed documents, posters, postcards, handouts, etc.

First off, the two most used PowerPoint slide sizes are:

  • 16:9 ratio  for onscreen presentations and new overhead projectors. This is the default setting for the latest versions of PowerPoint.
  • 4:3 ratio  for printing slides on standard 8.5 x 11 pieces of paper as handouts.

When starting with a blank PowerPoint presentation, changing your slide size is super easy and straightforward. If not, there are a few issues you’ll need to deal with, each covered below.

That’s why it’s worth figuring out what slide size you need BEFORE you build your presentation. If you later convert your presentation to a different size, it can be painful!

It’s just like the old carpenter saying, “measure twice and cut once.” In PowerPoint, you’ll want to “ask twice (to double confirm the required size) and build once.”

Changing your PowerPoint slide size does not make your PowerPoint presentation larger or smaller. To reduce your PowerPoint file size, you need to learn how to compress a PowerPoint presentation .

Table of Contents

How to change your powerpoint slide size.

By default, new PowerPoint presentations start in the 16:9 slide size format.

This is the NEW standard for most modern overhead projects and monitors and is recommended for most presentations. That said, you can easily change your slide size to something else.

To change your PowerPoint slide size, click the Design tab, open the Slide Size dropdown and choose the size for your slide

To change your slide size in PowerPoint, simply:

  • Navigate to the  Design tab
  • Open the  Slide Size  drop down menu
  • Select  4:3 ,  16:9  or  Custom Slide Size  (see options below)

When starting with a blank presentation, you are now good to go. You will not have to worry about any of the conversion issues discussed below.

Notice too, how much wider the 16:9 slide size is versus the 4:3 slide size in the picture below. The new size gives you more room for the content on your slides.

Comparison between the four by three and sixteen by nine slide sizes in PowerPoint

When you are converting an existing presentation to a new slide size, you will additionally be given the following prompt:

“You are scaling to a new slide size. Would you like to maximize the size of your content, or scale it down to ensure it will fit on the new slide?

presentation powerpoint slide size

Maximize  leaves all your content as is on your slide, even if it no longer fits on the new slide size that you selected.

Ensure Fit  scales down your content in proportion to the new slide size you have selected. You will only see this option when moving from a larger slide size to a smaller one.

Custom PowerPoint slide sizes

Choosing  Custom  for your slide size gives you additional options to work with. Inside the dialog box you can choose your size on the left and your orientation on the right.

presentation powerpoint slide size

On top of that, you can also input your own custom slide size. However, I recommend using one of the preset PowerPoint dimension options.

  • On-screen show (4:3)
  • Letter Paper (8.5×11 in)
  • A3 Paper (297×420 mm)
  • B4 (ISO) Paper (250×353 mm)
  • B5 (ISO) Paper (176×250 mm)
  • 35mm Slides
  • On-screen Show (16:9)
  • On-screen show (16:10)

For your orientation options on the right-hand side of the dialog box, you can choose between  Landscape  and  Portrait .

In most situations, you will want one of the default settings. Best practice is  Landscape  for your presentation slides and  Portrait  for your printed notes, handouts and outlines.

Issues when converting 4:3 to the 16:9 slide size in PowerPoint

When converting an existing 4:3 presentation with content into the 16:9 format, you are not given any conversion options. Instead, PowerPoint simply does the conversion for you, which can create several problems.

There are two issues you will face in the new 16:9 slide size.

When converting from four by three into the sixteen by nine slide size, your images will be stretched and distorted

The first issue is that all the images on your slide master (including company logos) will be stretched to fit the new, larger slide size.

To fix the stretched images, you will need to fix those images (or reinsert them) on your slide master, as if you were creating a PowerPoint template from scratch.

presentation powerpoint slide size

The second issue you will face in the larger 16:9 slide size is that you will have a lot of extra white space on your slides.

While you can leave the space blank, doing so will make your content look weird. Ideally you don’t want a lot of white empty space like that on your slides. Especially since all your font sizes will be so small.

That’s why if you have the time, I recommend resizing your content to fill in the white space. You can do this by either increasing the font size of your content, or adding additional visuals that support your message.

Issues when converting 16:9 to the 4:3 slide size in PowerPoint​

When converting an existing 16:9 presentation to the 4:3 slide size, you are given the option to either  Maximize  or  Ensure Fit  (both covered below).

1. The Maximize option

This option means that the content on your slides will not be resized to fit the 4:3 slide size. The same is true if you move to any smaller slide size.

when converting from the sixteen by nine to the four by three slide size, none of your content will be properly resized to fit the smaller slide size

Maximize Issue #1:  All the images on your slide master (including your company logo) will be distorted.

You might also have issues with other content placeholders, slide backgrounds or anything else that was built on your slide master.  For these issues, you’ll first need to navigate to your Slide Master. Once you are there, you either adjust (or rebuild) your PowerPoint template so that everything fits properly.

Maximize Issue #2:  Your content will not be scaled down to the smaller slide size. Instead, you’ll have overhanging content as pictured above.

For these kinds of spacing issues, you will need to work through your slides to adjust your content.

One recommendation as you move from the larger 16:9 slide size to 4:3, is to break up your slides. Take the contents from one larger slide and break it into two (or even three) separate slides.

Breaking up your content is preferable to just cramming more content on the smaller slide space. Doing so will make your content easier to read when presented on an overhead projector.

2. The Ensure Fit option

This option means that PowerPoint will scale down your content to fit the smaller slide size based on the size you selected.

when converting from the sixteen by nine to the four by three slide size, your images will be distored and you will have extra white space around the content of your slides

Ensure Fit Issue #1:  Distorted images, slide backgrounds and anything else that PowerPoint had to automatically resize on your slide master.

To fix these issues, you’ll need to navigate to your slide master and adjust (or rebuild) your template to make everything fit.

Ensure Fit Issue #2:  Your content will be scaled down to fit your new slide size, leaving you with a lot of white space. In addition, all your font sizes will be smaller, making them hard to read.

For small content like this, you’ll need to work through your slides and resize your content accordingly. Keep in mind the people at the back of the room too when choosing a new font style and size.

Saving your custom slide size as a PowerPoint theme

If want to use your own custom slide size for all your future PowerPoint presentations, you can save and set it as a PowerPoint theme.

This is a two-step process as discussed below.

1. Save your custom slide size as a theme

To save your custom slide size as a PowerPoint theme, from the Design tab, select save current theme, name the theme and click save

To save your custom slide size (and settings) as your own custom PowerPoint theme, simply:

  • Open the M ore options
  • Click  Save Current Theme
  • Name your Theme (and don’t change the file location it saves to)
  • Click  Save

2. Set your custom theme as the default

To set your custom theme as the default theme, from the design tab, find your custom theme, right-click the theme and select set as default theme

To set a custom PowerPoint theme as the default for all your future presentations, simply:

  • Open the  More options
  • Right-click  your custom theme
  • Select  Set as Default Presentation
  • Close out of PowerPoint (and do not save any presentations if it prompts you)

Once you’ve set your own custom theme as the Default Presentation, it will open every time you start PowerPoint. This saves you from always having to switch your slide sizes.

So that’s how you can change your PowerPoint slide size, either before or after you create your presentation.

And although you are given a lot of flexibility in the slide sizes you can choose from, I recommend using the default slide sizes as used by most people.

It’s also important to remember that switching slide sizes after you have built your presentation can be a total pain. So, to the extent possible, figure out your PowerPoint slide size first before you build out your presentation.

How to change the PowerPoint Slide Size: All you need to know

It’s always a good idea to know how to change Slide Size in PowerPoint, as you might have to adapt your presentation to different devices. Did you know that the default size of a PowerPoint slide depends on the version of the program you’re using? That’s another reason why the same content can look different on various devices, so it doesn’t hurt to be prepared for surprises and learn to scale your presentation properly in Microsoft PowerPoint. This tutorial illustrates how to change the PowerPoint Slide Size to match the screen of any device, using Windows 10, your iPhone, or Mac:

Skip to chapter

First things first: about powerpoint slide dimensions, how to change the powerpoint slide size in windows 10, how to change slide size in powerpoint on your mac, how to change slide size in powerpoint on your iphone, which powerpoint slide size did you end up using.

NOTE: This guide applies to Microsoft PowerPoint 2016 and 2019. If you’re not sure about your PowerPoint version, read What version of PowerPoint do I have? . You can download PowerPoint straight from Microsoft , but you must own the Microsoft Office suite or have an Office 365 subscription to use it. This tutorial covers only Windows 10, iOS, and macOS, because the option to change the PowerPoint Slide Size is not available on Android.

You’ve done your research, practiced your speech, and spent time adding visual aids for your audience. However, it can all be ruined if you created a presentation in Microsoft PowerPoint 2019, whose default slide size is Widescreen (16:9) , and you now have to use an old projector with the Standard (4:3) size. Your slides look different from what you originally intended and need to be adjusted to fit the screen you’re currently using.

To avoid any mismatches that might result in your pages being cut off on the edges or framed by black bars in Microsoft PowerPoint, change Slide Size as soon as you know where and how you’ll deliver your presentation. Unfortunately, not everyone knows which PowerPoint Slide Size is best in each situation. If you’re in doubt, you can always rely on the two most common PowerPoint slide dimensions:

  • Standard (4:3) – the default PPT Slide Size in PowerPoint 2010 and previous versions. Works best on older screens with low resolutions, old projectors, online presentation sharing platforms like SlideShare , and iPads.
  • Widescreen (16:9) – the default in Microsoft PowerPoint 2013 and newer. Works best on new screens with a wide aspect ratio (HDTVs, Smart TVs, LCDs, 4K monitors), new or HD projectors, Microsoft Surface devices, and online platforms like YouTube or Vimeo. Most laptops use a 16:9 aspect ratio, with the exception of MacBook’s 16:10 aspect ratio.

These are the only two settings available on iPhones. However, Microsoft PowerPoint offers you more Slide Size options in Windows 10 and macOS, such as Letter Paper or A4 Paper , which are better suited for printing your presentation. On top of that, if you want to optimize everything as much as possible, you can input a custom PPT Slide Size in inches, centimeters, or pixels, as you’re about to see in this guide.

IMPORTANT: It’s best to change Slide Size in PowerPoint before designing your presentation, to create a perfect canvas for your ideas. If you change the size of a PowerPoint slide after adding content to it, the elements and images you included might appear distorted and need further adjustments, so the sooner you find out the aspect ratio or resolution of the device you’re using for your presentation, the better.

Open the Microsoft PowerPoint presentation you want to work with or start a new project. To change the PowerPoint slide dimensions, first access the Design tab on the app’s ribbon. Then, you can find the Slide Size button in the Customize section on the right.

Depending on your screen and the size of the PowerPoint window, the option might be hidden. If you can’t see the button, press Customize to reveal it, and then click or tap on Slide Size .

Press the PowerPoint Slide Size button

Press the PowerPoint Slide Size button

This opens a dropdown menu with three available options:

  • Standard (4:3) - click or tap on this option to get slides of 10 x 7.5 inches or 25.4 x 19.05 cm.
  • Widescreen (16:9) - press to get slides of 13.33 x 7.5 inches or 33.867 x 19.05 cm.
  • Custom Slide Size - access this option if you are looking for something different than the two commonly used settings we discussed.

Choosing the last option opens the Slide Size pop-up window, where you can select a custom size to work with or change other slide aspects, like their orientation.

Once you are done choosing the slide size, click OK in the Slide Size window. In Microsoft PowerPoint 2016 and newer, you get a pop-up window and can choose how to change the slide size. This only happens when scaling down to a smaller Slide Size - e.g., from Widescreen to Standard . There are two available options:

Decide what happens with the content when you change Slide Size in PowerPoint

  • Maximize - click or tap on either of the two Maximize buttons to leave the contents of your slides as they are, without resizing them. If there is a lot of information on a slide, some elements might not fit anymore and bleed out.
  • Ensure Fit - reduces the size of your texts or images to fit the smaller slide size. While your content is not cut out, it does scale down in proportion to the new selected size.

The new slide size is immediately applied to your PowerPoint presentation.

TIP: If you are going to hold your presentation on a Windows device, read our tutorial listing 7 ways to find out your screen resolution to find the right size for your slides.

The options to change PowerPoint Slide Size on your Mac are similar to the ones in Windows. Access the Design tab and click on the Slide Size option on the right.

  • Standard (4:3) – click on this option if you want slides of 10 x 7.5 inches or 25.4 x 19.05 cm.
  • Widescreen (16:9) – clicking on this setting gets you slides of 13.33 x 7.5 inches or 33.867 x 19.05 cm.
  • Page Setup – lets you define a custom size (preset or custom) if the previous common sizes are not what you want for your presentation. Clicking on it opens the Page Setup pop-up seen below.

The size options in the Page Setup pop-up are identical to the ones found in Windows. Scroll up to the previous chapter to learn more about the preset values in the “Slide(s) sized for” dropdown menu or the custom ones you can insert in the Width and Height fields using inches ( in ), centimeters ( cm ), or pixels ( px ).

When you are done, click OK, and you get a different pop-up, asking you how to handle your content. If you choose to Scale , PowerPoint tries to fit everything into the new scale size, reducing your content size if needed. Clicking the Don’t Scale button keeps elements at their original sizes, even if they no longer fit correctly.

The new Slide Size is immediately applied to the presentation, with slide content being resized or cut if needed, according to your preferences.

On your iPhone’s slightly more basic version of PowerPoint, change slide size by accessing the Design options, which house the setting on iOS as well. The steps you need to follow are, however, not as straightforward on these devices. First, tap on the More button in the lower-right corner. Its icon looks like three horizontal dots.

TIP: If you need to know the aspect ratio of an iOS device, read our tutorial listing 3 ways to find the screen resolution of your iPhone or iPad .

If you must regularly create and send PowerPoint presentations at work, it may not be possible to choose the perfect size, as you can’t control the devices your audience is using. The best you can do is use our guidelines to ensure the content is optimized for most viewers. If you show a PPT or PPTX project to a larger audience, make sure to review your slides, test your file in advance on the exact device you plan to use, and leave time for any adjustments.

We tend to stick with the common PowerPoint slide sizes, which are good enough for most devices we come across. What about you? Which PowerPoint Slide Size did you select? Did you find it necessary to create a custom one, or did you end up using the preset ones? Tell us your story in the comments.

PowerPoint Slide Size: What is the Best Size for a Presentation

PowerPoint Slide Size

Whether you’re a business professional, educator, or public speaker, understanding what are the optimal slide dimensions can enhance the impact of your presentation. This guide will walk you through everything you need to know about the size of your PowerPoint presentation, from the basics to advanced tips.

What is the PowerPoint Slide Size?

PowerPoint slide size refers to the dimensions of the slides within your PowerPoint presentation. These dimensions determine how your content is displayed in a monitor or projector, and can significantly affect the overall look and feel of your presentation.

The most common slide sizes in PowerPoint are 16:9 (widescreen) and 4:3 (standard).

Choosing the right slide size is essential as it impacts how your content is perceived and ensures compatibility with various display devices. Once you define the optimal slide size for your next presentation, you can change the slide dimensions in PowerPoint following the steps described in our article.

Two popular slide sizes for presentations 16:9 and 4:3

It is important to understand the differences between Aspect Ratio and Pixel Dimensions.

The specific pixel dimensions for a standard 16:9 slide are 1920 pixels in width by 1080 pixels in height.

Understanding Aspect Ratio vs. Pixel Dimensions

Aspect ratio vs. pixel dimensions: what’s the difference.

When defining the optimal slide size for your presentation, it’s important to understand the difference between aspect ratio and pixel dimensions, as these terms often cause confusion but are critical for creating well-designed presentations.

Aspect Ratio

The aspect ratio refers to the proportional relationship between the width and height of your slide. It’s expressed as two numbers separated by a colon, such as 4:3 or 16:9. The aspect ratio defines the shape of your slide and how it will appear on different screens.

Pixel Dimensions:

Pixel dimensions, on the other hand, specify the total number of pixels in the width and height of your slide. This measurement determines the resolution and quality of your images and text in your PowerPoint slide size. For example:

  • 1920 x 1080 pixels: This is a common dimension for a 16:9 aspect ratio, known as Full HD. It provides high clarity and detail, making it suitable for large screens and high-resolution displays.
  • 1024 x 768 pixels: This dimension matches a 4:3 aspect ratio and is often used for smaller screens or lower resolution displays. It’s less detailed than 1920 x 1080 but can be effective for standard printouts or older projectors.

Why both slide size definitions matter? Understanding both aspect ratio and pixel dimensions is important because they impact how your PowerPoint slide size is viewed across different devices and formats. Here’s why:

  • Consistency Across Devices: Ensuring your aspect ratio is compatible with the display device prevents issues like black bars on the sides (letterboxing) or content being cut off (cropping).
  • Clarity and Detail: Choosing appropriate pixel dimensions ensures that your images and text appear sharp and clear, avoiding pixelation or blurriness.
  • Professional Appearance: Matching the right aspect ratio and pixel dimensions helps maintain a polished and professional look, whether you’re presenting on a large screen, sharing a PDF handout (as we will see later), or displaying your slides online.

The Impact of Slide Size on Different Industries

Different industries have unique needs when it comes to presentation slide sizes. For instance:

  • Business: Corporate presentations often require widescreen formats (16:9 slide size) to showcase detailed charts and data on modern projectors and screens. However, in some environments there are still projectors using the traditional 4:3 aspect ratio format for slide sizes.
  • Education: Lectures and workshops benefit from both 16:9 and 4:3 formats, depending on the teaching aids and screen setups used.
  • Design: Creative professionals need to create visually appealing slides that may require custom dimensions to stand out and effectively communicate their ideas.

Best Practices for Choosing a Proper Slide Size for your Presentation

When selecting an optimal PowerPoint slide size, consider the following:

  • Audience and Venue: Tailor your slide size to the screen size and setup of your presentation venue. Widescreen (16:9) is typically best for large screens, while standard (4:3) works well for print distributions.
  • Presentation Type: Webinars and online presentations held via Zoom or Teams , for example, often benefit from widescreen formats, while in-person meetings might require flexibility.
  • Aesthetics vs. Functionality: Balance visual appeal with readability and content integrity.

When creating PDF handouts from your PowerPoint presentation, it’s also important to choose a convenient slide size that ensures readability and clarity in print.

The 4:3 aspect ratio is generally preferred for printed handouts as it aligns well with standard paper sizes such as A4 or Letter. This format ensures that your content fits neatly onto the page without excessive margins or cropping.

Additionally, using 4:3 for print ensures that text and graphics are appropriately scaled, maintaining the legibility and professional appearance of your handouts. This consideration is essential for creating effective printed materials that complement your live presentations.

Overcoming Challenges with Slide Size

Adapting content for different slide sizes.

Resizing images and adjusting layouts can be challenging. Here are some tips:

  • Resizing Images: Ensure that images maintain their aspect ratio to avoid distortion.
  • Text Adjustments: Modify font sizes and text boxes to fit the new slide dimensions without compromising readability.
  • Consistency: Keep a consistent layout throughout your presentation to maintain a professional look.

Dealing with Mixed Slide Sizes in a Presentation

Sometimes, you may need to integrate slides with different dimensions. Here’s how:

  • Transition Techniques: Use smooth transitions to blend slides of varying sizes seamlessly.
  • Tools and Add-Ins: You can use PowerPoint add-ins that help manage and standardize slide sizes across your presentation.

Advanced Tips for Custom Slide Sizes

When it is time to innovate, the PowerPoint slide size can also play an important role. If you are considering to create a presentation for digital signage, or non traditional devices, choosing a custom PowerPoint slide size can help to achieve this. Here are some ideas and ways you can innovate by choosing a different slide size:

  • Unique Dimensions: Create custom slide sizes for branding or special events.
  • Custom Branding: Use non-standard slide sizes to align with your brand identity and marketing materials.
  • Innovative Uses: Experiment with different dimensions to create unique visual experiences.

For example, to create high-quality digital signage content, you’d need to set the PowerPoint slides to a 1920×1080 resolution in vertical (portrait) or horizontal (landscape) mode, which are the typical digital sign screen sizes.

Understanding what is the optimal slide size and how to configure it is essential for creating effective and engaging presentations. By optimizing your slides, and overcoming common challenges, you can ensure your visual aids are impactful and professional. Keep experimenting with different sizes and formats to find what works best for your needs. Remember, the key to a successful presentation lies in the details—choosing the right slide size is one of them.

How to Change Slide Size or Dimensions in PowerPoint

Change slide size or dimenstions in PowerPoint represented by widescreen or standard aspect ratio displayed on screen

Change PowerPoint Slide Size (Widescreen, Standard or Custom)

by Avantix Learning Team | Updated September 7, 2023

Applies to: Microsoft ® PowerPoint ® 2016, 2019, 2021 and 365 (Windows)

You can change the slide size or aspect ratio of a PowerPoint presentation in all versions. The default slide size or dimensions in 2013, 2016, 2019, 2021 or 365 is widescreen (16:9 aspect ratio). You can also enter a custom slide size if you prefer (including entering slide size in pixels). The best time to set slide size is when you first set up your PowerPoint presentation before you add any content. If you change the size later in the process, you may have to deal with distorted pictures and you may also need to adjust the position and size of various objects on slides in Normal View and in the slide master(s) and layouts in Slide Master View.

The most common slide sizes or aspect ratios are typically used as follows:

  • Widescreen or 16:9 aspect ratio is frequently used for onscreen presentations using a projector, monitor or a widescreen TV. Older projectors used the standard aspect ratio but most new projectors are designed for widescreen.
  • Standard or 4:3 aspect ratio is often used if slides are intended to be printed on letter size paper.

Slide size changes affect the entire presentation. You cannot change slide size for single slides.

You should never change slide size just before running a presentation as you may not be satisfied with the results. If you already have a presentation with images and other content, it's also a good idea to change slide size on a copy of the presentation so you can keep the original deck and slide size.

Note: Some Ribbon tabs may appear with slightly different names if you are working with PowerPoint 365 and have a smaller screen or different display settings. Buttons on the Ribbon may appear as icons only and are also affected by screen size and display settings.

Regardless of the version of PowerPoint you use, you should go through your slides after you change slide size to be sure you are satisfied with the results. Be sure to check the slide master(s) and layouts in Slide Master View as well.

Change slide size to widescreen or standard

To change slide size to widescreen or standard size:

  • In Normal View, click the Design tab in the Ribbon.
  • Click Slide Size in the Customize group. A drop-down menu appears.
  • Select Widescreen, Standard or another option from the drop-down menu. A dialog box appears with options to maximize content or scale to fit (this dialog appears only if you are moving from a larger to a smaller slide size).
  • Select the desired option.

Slide Size appears on the Design tab in the Ribbon:

Slide Size menu in PowerPoint

The following dialog box appears in PowerPoint to maximize content or scale to fit only when you change slide size to a smaller size (such as widescreen to standard):

PowerPoint dialog box to maximize or ensure fit when changing slide size to a smaller size.

If you select Maximize, the slide content will not be resized when you change to the smaller slide size.

If you select Ensure Fit, PowerPoint will scale your content to fit the smaller slide size.

Change slide size to a custom size

You can use custom slide sizes. Simply choose options from the Slides sized for drop-down menu in the dialog box (such as A4 paper size) or enter custom dimensions.

To change slide size to a custom size:

  • Choose Custom Slide Size from the drop-down menu. A dialog box appears.
  • Select an option from the Slides sized for drop-down menu or enter the desired slide size in the Height and Width boxes.
  • A dialog box appears with options to maximize content or scale to fit (this dialog appears only if you are moving from a larger to a smaller slide size).

Note that the measurement system in PowerPoint dialog boxes is based on your system settings. If you would like to change the measurement system, check out our article on How to Change the Measurement System in PowerPoint.

The following dialog box appears when you select Slide Size and then Custom Slide Size:

PowerPoint Slide Size dialog box to change slide size in 2013, 2016, 2019 and 365.

You can create posters in PowerPoint by entering a custom slide size such as 36 inches wide by 56 inches high or 91.44 cm wide by 142.24 cm high. The maximum slide size in PowerPoint is 56 inches or 142.24 cm. As a best practice, set the slide size before adding content to the poster.

Many PowerPoint users are not aware that you can enter slide size in pixels (simply enter the measurement with px beside the number). This is useful in a number of situations such as using PowerPoint to create social media posts. If you enter slide size in pixels (such as 200px), when you tab to another box or close the dialog box, PowerPoint changes the pixels to the equivalent in the current measurement system.

Deal with issues when changing slide size

When changing slide size in existing presentations with content, 4 common issues occur:

  • Pictures may be distorted as PowerPoint tries to adjust images to fit slide size. Images on slides in Normal View will be affected as well as images on the slide master(s) and layouts. If pictures are distorted, you will need to either manually resize each image or delete them and insert them again.
  • Objects such as placeholders and shapes that have been created in PowerPoint are not in the position you'd like. You may need to move objects or reset one or more slides (on the Home tab in the Ribbon, click Reset in the Slides group).
  • Extra space is created if you change to a larger slide size. You may need to move or resize objects and adjust the slide master(s) or layouts in Slide Master View.
  • If you have changed to a smaller slide size, you may need to increase font size for placeholders and text boxes.

Dimension differences between different slide sizes

In PowerPoint 2013 and later versions, widescreen (16:9) format measurements are different and are set to 13.33 inches wide by 7.5 inches high or 33.867 cm wide by 19.05 cm high. This matches the height of the 4:3 format.

Avoid issues when changing slide size

To avoid issues in PowerPoint related to slide size, you should:

  • Try to set slide size as a first step after you create a presentation and before you have entered any content. In 2013 and later versions, the default is widescreen (16:9 aspect ratio).
  • If you have changed slide size in a presentation with content, review your slides to be sure you are satisfied with the results. You should also check the slide master(s) and layouts in Slide Master View.
  • Never change slide size just before running a presentation as you may not be pleased with the results and you won't have time to fix your slide deck.
  • If you have created a presentation with content, make a copy of the presentation first and change slide size on the copy.

Keep in mind that widescreen is normally used for on screen presentations and standard is often used for printed presentations.

How to Change the Slide Size in PowerPoint for Better Presentations

Makes them much easier to read

Author avatar

Powerpoint presentations are supposed to be engaging. But that’s another story if the audience can’t see what’s in front of them. So, in this article, we’ll discuss how to change the default slide size in Powerpoint.

This will come in handy so you can maximize your slides to the size of the projector or monitor you’ll be using and deliver a better presentation.

How to Change the Slide Size in PowerPoint for Better Presentations image 1

Choose One Slide Size First

PowerPoint allows you to change the slide size anytime you like, but it’s a good idea to pick the right size before you start creating your presentation.

If you decide to change the size later, PowerPoint will do its best to give you options on how to shift items around, but it will more than likely result in having to totally redesign your slides.

This is especially true if you move from a widescreen format slide to a smaller 4:3 standard sized slide.

How to Change the Slide Size in PowerPoint for Better Presentations image 2

If you choose to scale it down, PowerPoint will try to fit everything as best it can into the smaller slide. If you choose Don’t Scale , the items that are outside the standard size will simply be out of the window. You’ll then have to decide whether to delete those items or move them back into the slide.

Change Slide Size in PowerPoint

Once you know what size will be ideal for your output device, you can adjust the slide size in PowerPoint.

First, go ahead and open PowerPoint and select a slide.

How to Change the Slide Size in PowerPoint for Better Presentations image 3

This guide works will work for most modern versions of PowerPoint that have the ribbon interface, including the version in Office 365.

Next, go to the Design tab. It’s where you can find the options that let you tweak your presentation’s design.

There, head over to the far right end — to where you can find the Customize section. Next, choose Slide Size .

Clicking on this option will reveal a menu. It lets you pick the size of the slide that you want. Your choices are Standard , Widescreen , and Custom Slide Size .

Let’s walk through each of the choices. This way, you will have a better understanding of your options. This will also help you adjust your slide’s size as needed – a size that works best for your projector or TV.

If you go with the Standard size, you’ll be going with a 4:3 aspect ratio. This is a safe choice because it works for familiar devices such as older screens with low resolutions.

A Standard slide size is a suggested choice for old school presenters. This means those who will be working with old projectors and SlideShare or other old online presentation platforms .

How to Change the Slide Size in PowerPoint for Better Presentations image 7

If you choose Widescreen , you’ll be going with an aspect ratio of 16:9. This is the ideal choice for you if you’re dealing with newer devices and online presentation platforms.

Got a Microsoft Surface device or HD projector? Going with a Widescreen option is the better way to go. The same is true if you’ll be presenting on a HDTV or 4K TV/monitor.

If Standard and Widescreen slide sizes are not for you, you can also go with the Custom Slide Size…

If you select this option, a pop-up window will appear.

Here, you can select from plenty of choices regarding the slide size you want. If you’re about to deliver your Powerpoint presentation on an unfamiliar projector, it’s good to go with this option.

It’s flexible. It can also accommodate your preferred slide dimensions.

Plus this way, you can select the Orientation for your slides and notes. This lets you have control over the Width and Height of your slides, too.

How to Change Slide Size in PowerPoint? [A Helpful Guide!]

Microsoft PowerPoint is a powerful software. You can not only create a standard presentation design, but you can also create documents of various sizes using PowerPoint! However, that requires you to have a good understanding of various slide sizes available in PowerPoint. You may be wondering, how to change the slide size in PowerPoint?

To change the slide size in PowerPoint, click on the “Design” tab. Then, click on “Slide Size”. From the dropdown, choose “Standard” or “Widescreen”. You can also click on “Custom Slide Size” to change the size of the slides in PowerPoint to A3, A4 or a completely custom size.

In this article, I will walk you through the nuances of changing a slide size in PowerPoint. We will go into the steps in detail with pictures so that you get the best understanding of the subject!

So, let’s get started!

A Quick Note Before We Begin – for this article, I will be using one of the presentation templates from Envato Elements . With Envato Elements, you get access to thousands of presentation designs with unlimited downloads so you never run out of options again. Plus, you get free previews so you know exactly what you’re getting before buying! It is also very affordable.

1. How to Change Slide Size in PowerPoint? 

Changing the size of your slides in Microsoft PowerPoint is actually a lot easier than you think! All you have to do is go to the ‘Design’ tab from the ribbon, click on the ‘Slide Size’ button at the top right corner of your screen and select the slide size you want.

Below, I’ll be discussing how to change the size of slides in different versions of Microsoft PowerPoint as well as in different device including Mac, iPad and Android:

1a. Change Slide Size in PowerPoint 2016 and 2019

Follow the steps below to change the slide size in Microsoft PowerPoint 2016, PowerPoint 2019 and Office 365:

Step 1: Click on the ‘Design’ tab

At first, click on the ‘Design’ tab, which is the fourth option on your ribbon to get access to the design section of your PowerPoint presentation.

Step 2: Click on ‘Slide Size’ option

Go to the top right of the ‘Design’ tab in the ‘Customize’ section and ‘Left click’ on the ‘Slide Size’ button and a drop-down menu will open.

Step 3: Select the desired slide size from the ‘Slides sized for’ option.

Now, another dialogue box will show up in the middle of your screen. Click on ‘Ensure Fit’ to adjust your slide contents. (we will talk about the difference between the “Maximise” and “Ensure Fit” options later in the article)

If you choose to click on the ‘Custom Slide Size’ option, you may see a different dialogue box first. We will get to that in a moment and I will share with you how to customize the slide sizes in addition to the default options provided by PowerPoint.

1b. How to Change Slide Size in PowerPoint 2010? 

The process of changing slide size in Microsoft PowerPoint 2010 is described below:

Step 1: Click on the ‘Design’ tab and go to ‘Page Setup’ option

Click on your preferred slide size and then press the ‘Ok’ button. PowerPoint will prompt you to choose between “Scale” or “Don’t Scale”. This is similar to the Maximise or Ensure Fit options Windows users see.

Go with the “ Scale ” option as this will adjust the sizes of all shapes and text for each slide. You can also choose to go with “Don’t Scale” option and adjust everything manually as per your requirement.

Your slide size will change accordingly.

Step 3: Change your slide size from Widescreen to Standard and adjust slide content

If you click on the ‘Maximize’ option, your content will not be sized down to fit your slide and images may get distorted. On the other hand, clicking on the ‘Ensure Fit’ option will resize the contents of the down to your preferred size.

6. How to Increase Slide Size in PowerPoint When Printing? 

When printing, sometimes PowerPoint just doesn’t print to the edge of the page. Meaning, there is a white bleed (border or margin) when you try to print it or when you try to convert it into a PDF.

You can fix this problem by either increase or adjusting the slide size before printing.

Here’s a video that explains the process in detail –

Although the video is for Mac, you can easily adjust the settings for the slide size for Windows just the same way.

It is important to remember to make sure that you don’t increase the slide size of your entire presentation but only adjust the printing size of the slides.

7. Can You Change Orientation of Just One Slide in PowerPoint?

There is currently no direct way to change the orientation of just one slide in PowerPoint. However, you can circumvent this issue by either creating a hyperlink to an external file or adding a portrait PDF file directly in PowerPoint.

We wrote a detailed article on the exact steps and processes that you need to follow in order to do this. Make sure you read that article on How to Change Orientation of Just One Slide in PowerPoint !

Cheat Death by PowerPoint!

What size should my slides be, 16:9 or 4:3?

July 3, 2017 by Laura Foley 2 Comments

Deciding on a slide format used to be easy when there was only one choice. Nowadays, you can choose between 4:3 format or 16:9. What do these numbers mean and which size should you choose for your presentations?

What the numbers mean

The above notation is called the “aspect ratio,” or the ratio of the width to the height of the slide. In the 4:3 aspect ratio, the dimensions are 1024 x 768 pixels (10.67″ x 8″); the height is 3/4 of the width. Back in the Ye Olde Days of PowerPoint, it was your only choice. Why? Because that’s the aspect ratio of actual slides, pictured above, television screens, and early computer monitors.

When high-definition screens came on the scene in the early 2000s, they were built in a 16:10 aspect ratio. But as more and more high-definition screens were manufactured, it became clear that screens with a 16:9 aspect ratio were cheaper to manufacture. So the 16:9 aspect ratio (1920 x 1080 pixels or 13.3″ x 7.5″) became the new standard.

What size should you choose?

From boardrooms to computer monitors to smartphone screens, 16:9 is the default screen aspect ratio so that’s the slide size I always go with. The 16:9 format gives you a lot of slide real estate to play around with! The legacy 4:3 aspect ratio, while still used, creates smaller slides and doesn’t look that great on newer screens.

How do you change an old 4:3 deck to the new 16:9 format?

Oh, this is super-fun to do and you’re a lucky duck if it becomes your job.

To resize your slides go to the Design tab on the ribbon and select Slide Size/Widescreen on the right side of the screen.

slide size

After you select the new size, this window will appear:

Slide scaling window

Now you’re faced with either everything on the slides being stretched out or squished to fill the space. Oh boy! Either way, after you make your selection you’ll need to go through the presentation slide by slide to ensure that everything looks good. This can be fairly straightforward if the creator of the presentation stayed within the template or a real pain in the rear if he/she didn’t. But do go through the deck to ensure that everything looks right.

If you’re a production artist that charges by the hour, reformatting an organization’s slides from 4:3 to 16:9 could be a nice little gig for you!

Other slide sizes for special events

Now, the 16:9 format is great for everyday use but what if you’re designing a presentation for an event? Last year, I was designing slides for a corporate conference where the setup included multiple, massive screens. For that event, the slides measured 52″ x 17″ and had a “leave this space blank” area on the bottom. Each event is different, so if you’re working on slides like these you need to become friends with the AV folks and find out what size slides they recommend for optimal viewing on that particular setup. The last thing you want to see on a gigantic stage are distorted graphics!

Bottom line

Unless you’re told otherwise, use the 16:9 format. You get a lot more space on each slide for your visuals and it’s really the way things are going.

A better way to change your slide sizes in PowerPoint without breaking it.

  • October 6, 2021
  • Tips and Ticks

An easy way to change slide sizes in PowerPoint presentations to 4:3 (Standard) or 16:9 (Widescreen) formats without breaking your theme and template or stretching your logos and images.

Resize PowerPoint Aspect Ratio Options

As with most things related to technology, there is more than one way to skin the cat – or in our case to resize PowerPoint presentations. We are going to discuss both the standard way ( as well as why we don’t recommend it ) and the right way, using our FREE PowerPoint resizing tool.

If you ever changed a presentation to Standard or Widescreen sizes in PowerPoint and thought you would likely agree that the outcome was unpredictable and undesirable.

TLDR: If you want to skip the details and go straight to the instructions on how to use our FREE PowerPoint presentation resizing tool to change slide sizes without breaking your slide content then Click Here .

Why the standard solution does not work:

In short, the standard way to resize your PowerPoint changes and breaks your fonts . Using the PowerPoint resize tool also stretches images , graphics, and logos on your slide and Slide Master Layouts.

The best way to explain what is wrong with this method – is to show you. With your presentation open go to the Design Ribbon and click on the Slide Size drop-down menu and select either the Standard(4:3) or Widescreen(16:9) aspect ratios.

You can pick either ‘Maximize’ – which will cause your content to flow over the edges of the screen or ‘Ensure Fit’ which will create empty gaps on either side of your presentation.

Whichever of the two options you select the result is not going to be what you want. Your slide content probably looks broken, logos might be stretched, the theme’s font has changed to Calibri, your corporate colors might have disappeared and your Master Layout’s placeholders are resized disproportionally.

Visual representation of why the standard solution of PowerPoint resize does not work

METHOD 1: The standard way, how to change PowerPoint Slide Sizes in Windows 10 or Mac:

Part 1: before you change your powerpoint slide size.

Step 1:   Make sure your presentation is in its original working format.

Step 2:  Save your Theme color scheme.

1) Click on the View Ribbon, 2) then the Slide Master button

PowerPoint Slide Master View

3) Click on the Colors drop-down menu and then on the 4) Customize Colors… button at the bottom of the list.

PowerPoint Slide Master - Custom Colors

At the bottom of the Colors dialog box give your color scheme a name in the Name field – and call it whatever you want but remember the name because we are going to use that after we resize our template. Click on Save.

PowerPoint Slide Master - Save Theme Color

Step 3: Save your Theme fonts

1) While still on the Slide Master Ribbon click on the Fonts drop-down menu and then on the Customize Fonts… button at the bottom of the list.

PowerPoint Slide Master - Save Theme Fonts

2) In the Name field give your Theme Fonts a name that you will use and click on the Save button. 3) Close the Slide Master Ribbon by clicking on the “Close Master View” button.

PowerPoint Close Master View

Part 2: After you change your slide size

Step 4: Resize your PowerPoint presentation

After you close the Slide Master Ribbon the Design Ribbon should be visible again. Click on the Slide Size drop-down menu and select either the Standard(4:3) or Widescreen(16:9) aspect ratios and select the ‘Ensure Fit’ option ( it is easier to move items around than to also have to resize them especially when converting to a larger slide size ).

Step 5: Reselect your Theme color and Theme font

With the Design Ribbon still active click the Variants drop-down menu, then color and select the Color Theme you saved earlier, and then do the same for your fonts.

Step 6a: Fix stretched images – Method 1

Here is a quick hack to fix stretched graphics and images.

1) Right-Click on the stretched image and select “Size and Position” to open the Size and Position Task Pane. You will notice the Scale Height and the Scale Width are different, for example; Scale Height might be 99% and Scale Width might be 74%.

2) All you need to do to fix your image is press the up or down arrow on either the Width or Height and voila, your image is no longer stretched. If that doesn’t work then make sure Lock Aspect Ratio is checked.

Step 6b: Fix stretched images – Method 2

Another way to resize your images is to reset your images. To do this you simply select your image and then from the Picture Format Ribbon select the Reset Picture drop-down menu and select Reset Picture & Size button.

Step 7: Move placeholders, content,  and images into their new position.

The last thing to do is move items such as placeholders and images around on your presentation to make them fit better.

METHOD 2: The better way, to change your slide dimensions:

Step 1:  Go to our FREE resize tool Go to our FREE PowerPoint resize tool and Upload your PowerPoint file: www.knockoutprezo.com/resize-powerpoint

Step 2: Select a file location and select your PowerPoint document

Step3: Select whether you want to resize to Standard or Widescreen sizes. Once you make your selection the file will upload, convert the PPTX and then then the download will start automatically.

  • PowerPoint won’t stretch your images and graphics
  • No more missing colors
  • Your theme fonts stay as it was ( Header and Body fonts )
  • Your layouts stay in their original location which is a lot more predictable and easier to work with.

Unfortunately, the resizing tool did not work for my use case. It simply overlayed a different slide deck formatting, but didn’t change any configurations, which made the deck useless. I like the thought for this tool though, as reformatting slides is a huge pain and time drain.

Do you mind me asking about your feedback about our resize tool. I didn’t quite understand your feedback.

Essentially what the tool does is that it resizes the deck without breaking, stretching etc the presentation assets, HOWEVER the user still needs to adjust the elements of the presentation. Did you go from 16×9 to standard or the other way around? There isn’t a way for the software to tell if you want an element aligning to the left, middle or right of the slide for example.

How to change slide size in PowerPoint

  • March 25, 2021

Courtney

Trying to change slide size in PowerPoint presentations? PowerPoint lets you choose between a couple of standard slide sizes, plus a custom size option. In this hints and tips blog post we provide a guide to:

  • The different slide sizes in PowerPoint 16:9, 4:3 and custom sizes
  • How to change a PowerPoint slide size
  • How to change the orientation of PowerPoint slides from landscape to portrait
  • A workaround to change selected slides to portrait for printing

Where to change slide size in PowerPoint?

From the PowerPoint Design tab on the ribbon, select the Slide Size feature button. You can find the slide size feature button on the far right end of the ribbon - refer to the screenshot below.

Screenshot powerpoint ribbon design tab select slide size menu to change slide size

The three slide size options of standard, widescreen and custom will display, as shown in the screenshot below.

screenshot of MS PowerPoint slide size options on design tab

What are the PowerPoint slide size options?

PowerPoint offers three different slide sizes. What's the difference 4:3 vs 16:9 PowerPoint slide sizes? The Standard 4:3 and Widescreen 16:9 both have the same slide width , but have different slide heights:

  • PowerPoint Standard (4:3) Slide Size: This is the original PowerPoint slide size. The standard screen size is easy to print and works well on older style pull down projector screens (when the screen shape is closer to a square than the newer widescreen layout). Powerpoint 4:3 dimensions are 10 in x 7.5 in (which is 33.867 cm x 19.05 cm). Standard PowerPoint slide size pixels = 1024 px x 768px
  • PowerPoint Widescreen (16:9) Slide Size: The PowerPoint 16:9 widescreen option was a later addition but is now the default value in PowerPoint for new presentations. Widescreen is more commonly used now because the size is well suited for presenting on digital screens (typically shaped like elongated rectangles similar to a current TV screen). Powerpoint 16:9 dimensions are 10 in x 5.625 in (33.867 cm x 14.288 cm). Widescreen size 16:9 size ppt dimensions pixels = 1920 px x 1080 px
  • On-screen show (4:3)
  • Letter Paper (8.5x11in)
  • Ledger Paper (11x17in)
  • A3 Paper (297x420mm)
  • A4 Paper (210x297mm)
  • B4 (ISO) Paper (250x353mm)
  • B5 (ISO) Paper (176x250mm)
  • 35mm slides
  • On-screen Show (16:9)
  • On-screen show (16:10)

screenshot of slide size popup menu in powerpoint

You can either select from one of the many options in the drop down list, or you can directly key in your preferred Width and Height for your PowerPoint presentation. As soon as you key in width and/ or height values, the drop down menu will update to show the Custom option.

Note that when you are entering a custom slide size, you have the option to specify your PowerPoint size in pixels (e.g. specify pixels for width and height). You can do this by typing in your preferred height and width in pixels using px at the end. The minimum width or height in pixels for PowerPoint slides is 120 px and the maximum width or height is 720 px. When you specify pixel size of PowerPoint slides, PowerPoint will convert the pixels automatically to your default unit of measurement (e.g. either cm or in).

You can then select the Orientation of PowerPoint slides. You have the option of Portrait or Landscape orientation - by default PowerPoint displays in Landscape format. You can select the orientation separately for the slides and the Notes, Handouts & Outline.

What PowerPoint slide size should I use?

Before the popularity of larger monitors, the 4:3 slide size in PowerPoint was the more commonly used option. 4:3 slide size is smaller and better suited to older PC monitors and older pull down projection screens.

However large monitors have now become commonplace both for use in offices and for presentation in meeting rooms. As a result - 16:9 PowerPoint slide size would now be considered the default. The 16:9 slide size is wider than the 4:3, which gives you a bit more space to work with when creating slides, especially consulting style layouts with charts or images beside text.

If you are presenting to a large audience, and/or if you are submitting slides that are being consolidated into a larger presentation, it's worth checking with the coordinator or location AV team for any guidance (for example some theatres may have screen setups which benefit from custom presentation sizes).

Can I resize selected slides in a PowerPoint presentation?

No - the PowerPoint resize option is applied to all slides in your presentation. You cannot change size of selected slides in your PowerPoint presentation.

Does PowerPoint auto resize content if slide size changes?

If you select to change the slide size for an existing presentation, PowerPoint will display a slide scaling popup menu. The menu will give you the following options for scaling your slides:

  • Maximise : The maximize size scaling option in PowerPoint will make the content larger, but it may spill over the edges of your slide.
  • Ensure Fit: The ensure fit scaling option in PowerPoint ensures that all content remains visible on the slide, however the content may shrink to ensure that it fits.

Screenshot PowerPoint change slide size resize content popup

It's a good idea to review your content after completing the change of PowerPoint slide sizes - even if you select the ensure fit option you may need to adjust the content on some slides.

Can I change orientation of PowerPoint slides from Portrait to Landscape?

Trying to work out how to change PowerPoint to portrait layout? You can change the orientation of your PowerPoint slides from Landscape to Portrait for the entire presentation, (you cannot change only selected slides in a presentation). To change orientation of PowerPoint slides:

As per the steps above, from the PowerPoint Design tab on the ribbon, select the Slide Size feature button (on the far right end of the ribbon).

Screenshot of powerpoint ribbon design tab selecting slide size menu

The three slide size options will display, as shown in the screenshot below. Irrespective of what size layout you want this time, you need to select the Custom Slide Size option from the PowerPoint ribbon.

From the Slide Size popup menu on the PowerPoint ribbon, you have the option to select Portrait or Landscape mode. You can select the orientation display without modifying your slide size if you already have the correct slide size selected.

You can change the orientation for both your PowerPoint slides and handouts. Note that changing the orientation e.g. from Landscape to Portrait does not automatically adjust your PowerPoint template (your logos will likely appear distorted and the title page of your presentation will look squished). You need to adjust your PowerPoint template separately. If you are changing orientation only for a single PowerPoint presentation, you can do this via your presentation's Slide Master. Or if you plan on creating multiple presentations in the new orientation, its worth spending the extra time to create a new .potx template file, suited to the new orientation.

Can you have different orientation slides in a PowerPoint? presentation?

Trying to add a vertical slide in PowerPoint, but keep the rest of the presentation horizontal? Unfortunately it's not possible to have a combination of Portrait and landscape slide orientations in a single PowerPoint presentation. But there is a workaround if you are printing rather than online presenting your PowerPoint presentation.

If you are preparing a PowerPoint presentation that will be printed, a workaround to include different orientation pages in PowerPoint is to create a slide master layout with the orientation on its side. This is a way to rotate PowerPoint slides to Portrait without changing all slides. Refer to the screenshot below for an example.

presentation powerpoint slide size

Why would anyone want to change the slide size in PowerPoint? You open a file, it’s the perfect 16:9 (no 4:3 fans here!), and you get stuck in, right? Well, it depends what you’re using PowerPoint for…

Presentations are a powerful tool for communicating with your audience. But if you’re making presentations, the chances are you’re also looking for other ways to get your message out there. Perhaps you want to share news on your social media feeds, present a poster at a conference, have downloadable brochures on your website, or create business cards to hand out to unsuspecting members of the public.

You might be thinking, that sounds great, but I don’t have the tools to do all that! Would you believe me if I told you can do all this and more in good-old-PowerPoint?

PowerPoint is easy-to-use, quick to edit, and is super versatile. The feature that makes creating all these different materials possible is the ability to change the size of PowerPoint slides to your desired dimensions. ‘But how?’ I hear you cry. Well, cry no more! In this blog post I’ll teach you how to change slide size in PowerPoint.

If you’re a Google Slides user who’s wandered into the wrong blog post – this one on changing slide size in Google Slides might be what you’re looking for.

Quick guide:

  • In the Design tab choose Slide Size . The highlighted box shows the current dimensions of your slides.
  • In the Slide Size drop down, select Custom Slide Size .
  • Select the slide size you want to use.

Step-by-step:

To know what to change, you need to know where you’re starting. When you open a brand new PowerPoint file, the standard slide dimension is widescreen (16:9). This is ideal for presentations because it matches the size and proportions of most modern screens.

screenshot of PowerPoint showing the Slide Size drop down menu

To check your slide dimensions head to the Design tab then choose Slide Size . The highlighted box shows you the current dimensions of your slides.

To change your slide size, under the Slide Size drop down, select Custom Slide Size .

Same as above but with the Custom slide size option highlighted

A pop-up box appears, and you can customise the slide size to suit your needs.

What’s helpful is that PowerPoint already has options built in for standard formats, such as Letter paper and A4, so you don’t have to spend time searching the web for the dimensions you need.

Slide size pop up

Not every combination of width and height is available in this drop down (including the dimensions for popular social media sites). So if you need a truly custom slide size, you can directly input your measurements. Select Custom from the drop-down list and type in the Width and Height you need.

Slide size pop up with 'Slides sized for:' drop down open

PowerPoint will ask you if you want to ensure fit or maximize fit. Typically you would choose to maximise when increasing the size of your slides, and ensure fit when decreasing slide size.

pop up described in text

Maximise will increase the size of any existing content on the slide, but as a result, all the content might not fit on the slide. Ensure fit scales down the size of existing content making it appear smaller but ensuring all the content fits on the slide. This is why it’s best to set the slide size right at the beginning and then you don’t need to worry about this.

After you’ve made your selection, select OK , and hey presto, you’ve done it.

For this example, we’ve chosen the size of a regular square Instagram post.

screenshot of a square PowerPoint slide with slide size pop up

Converting aspect ratio to dimensions

Just a side note on working out what slide size you need for creating social media posts. When you look up dimensions for an Instagram post, the most popular Google results tell us it’s 1080px by 1080px, but as you can see in the screenshots above, it looks like PowerPoint wants us to input our dimensions as cm. This can be a little confusing, especially for us non-designers out there who don’t know our pixels (px) from our points (pts). There are lots of websites online that can help you convert your measurements, like here – www.unitconverters.net . However, it’s a little know fact that you can enter dimensions in cm, inches or pixels and PowerPoint will convert it for you! Just type the numbers, then a space and then the unit abbreviations (cm, in, px). For a comprehensive guide on all social media image sizes check out this article by Brandwatch .

A regular Instagram post is a square, so that’s easy as the ratio is 1:1, meaning the width is the same as the height. With rectangles, the ratio of width to height will differ. A LinkedIn post for example, can either be portrait 1080 x 1350 or landscape view at 1280 x 720. So for the portrait the ratio is 4:5 and landscape is approximately 16:9. Don’t let this intimidate you. If you divide both sides (width and height) by the same amount you guarantee the ratio will stay the same.

If you’re entering slide size details as centimetres make sure you consider the overall slide size in cm as this will affect the size of an image export, which in turn can affect the quality of your exported image. Put simply an Instagram post made on a 2cm by 2cm slide will be poorer quality than one made on a 10cm by 10cm one. We have a helpful blog post that goes into much more detail on Picture size and resolution in PowerPoint .

Now that you’re a pro on how to change PowerPoint slide size, let’s go through some examples of the awesome things you can do with this new knowledge. But before we do that just a note – there are dedicated software to create a bunch of the things we’ve mentioned in this article. If you have access to it, that’s amazing! Use it! But for many of us, PowerPoint is one of our only design tools and purchasing a handful of other programs isn’t on the cards, so we need to get the most out of PowerPoint that we can.

Academic posters

For researchers and students alike, creating academic posters can be one of the more gruelling tasks on your to-do list. For most people that’s because they struggle to make posters look beautiful and engaging meaning people miss out on reading your incredible work! With your new knowledge of how to change slide size in PowerPoint, you can start making A4 and A3 posters in PowerPoint.

Some things to remember…

A poster should never be an impenetrable wall of text but a visual summary of your work. It should be concise with plenty of white space, accessible, with a clear and logical layout. A great poster is a conversation starter that drives the audience to learn more.

On the left of the image is a dense, text filled poster. On the right is the same poster with a face lift, less text, better visuals and more cohesive design.

We have a whole blog post on to how to create beautiful and effective academic posters in PowerPoint , so make sure you give that a read for more tips and tricks and a couple of cheeky freebies!

Social media posts

Once you know how to change slide size in PowerPoint you can create graphics for all your social media channels. Whether it’s for Instagram, LinkedIn, Facebook or Twitter… sorry X, we’ve got you covered.

PowerPoint Slide Size

PowerPoint allows you to change the aspect ratio of your presentation. The widescreen slide size is best when presenting on modern displays with a 16:9 aspect ratio. If you’ll be presenting on an older display with a 4:3 aspect ratio, you’ll want to use the standard slide size instead.

Change the Slide Size

  • Click the Design tab.
  • Expand the Customize group.

To change the slide orientation, click the Slide Size button and select Custom Slide Size . Change the slide settings and click OK .

  • Widescreen : 16:9 ratio is much wider than it is tall and works well for wide, high definition screens.
  • Standard : 4:3 ratio is only slightly wider than it is tall and works best for traditional screens.

Slide Size

  • Maximize : Crops your content and fills all the available space on the slide.
  • Ensure Fit : Scales content down and leaves additional space at the top and bottom of the slide.

What PowerPoint Slide Size to Use?

Since the adoption of the widescreen format for our audio-video equipment, what is the PowerPoint slide size to use?

When PowerPoint 2013 was introduced, the default aspect ratio for slides was changed from 4:3 to 16:9. The aspect ratio is defined as the ratio of width to height. This is in line with most modern equipment such as projectors and televisions that have adopted the 16:9 widescreen format.

So, what PowerPoint slide size to use? Should we shift accordingly to the widescreen format? What are the differences between the two formats and the critical issues we need to know?

The following article will provide a brief explanation of the differences in using the 4:3 and 16:9 format. We will also provide a guide on which PowerPoint slide size to use in our presentation.

The 4:3 slide dimension was the standard in the past era of analogue TV screens. But they have since been replaced by the widescreen adopted by most projection equipment. These include television, computer screen, LCD monitors, etc. As both formats are still being used, we must be aware of the compatibility issues and know how to rectify them.

The slide dimension of 4:3 and 16:9 refer to the aspect ratio of the slide rather than its actual size. A 4:3 slide is 33% wider than it height while a 16:9 slide is 78% wider than its height.

What is the Preferred PowerPoint Slide Size to Use?

Many people are unsure what is the preferred PowerPoint slide size to use. Unfortunately, the answer could either be a straightforward or difficult one, depending on the information we have. Obviously, we should design our presentation according to the following:

  • Use 4:3 in an environment where previous presentations and the current equipment used are in the 4:3 format.
  • Use 16:9 in an environment where the presentations and equipment have been upgraded to the 16:9 format.

This seems like a no-brainer, isn’t it? But, what if the organizer cannot provide you with the specification of the projector and screen size? Such a situation is not uncommon, especially if you are doing presentations at client sites or at their hired venues.

Although many facilities have switched to the latest 16:9 widescreen standard, we are in a period of transition. The previous 4:3 aspect ratio is still commonly in use in many facilities. So, do not be surprised to find yourself in an organization that still uses equipment in both the 4:3 and 16:9 format. If unlucky, you may end up in a presentation room where the projector’s format differs from the one you designed your PowerPoint slides on. Given such an uncertainty, what should we do?

In general, the 4:3-aspect ratio works for most projectors. BUT when projected on a widescreen, the slide will not fill up the entire screen. Black bars will appear on both sides of the slide. Although this is not ideal, the slide will still retain its full height and the text will not be shrunk.

When a 16:9 slide is shown on a projector in 4:3 aspect ratio, black bars will appear on the top and bottom of the slide. What this means is that it will not fill the entire height of the screen. This has the effect of compressing the text and make it smaller than planned.

In general, 4:3 slides work for most projectors despite it not filling up the entire screen. Although we can easily convert our 4:3 slides to 16:9, they will become stretched and distorted. But this is preferable to having a 16:9 slide on a 4:3 projector where the text will be compressed. This renders them less readable. Although this problem can be rectified, it is time consuming.

As far as possible, find out the equipment specification in your presentation venue. This will save you a lot of headache later on. If your are unable to, and until such a time when equipment using the previous standard have been phased out, it may be a good idea to stick to the 4:3 format. Of course, if you have the time, design your presentation in both the 4:3 and 16:9 format to be absolutely safe. Never underestimate the importance of an effective PowerPoint design as it can impact how information or knowledge will be delivered.

How can I determine the size of individual slides in a PowerPoint slide deck?

I have a powerpoint file containing images and it has gotten too big for emailing and I need to decide which slides to cut out. But how can I tell which slides are consuming all the space? There could be just a few slides containing over-large images, but how do I know which slides they are? Is there any way to know the filesize of individual slides?

There is a built-in way to measure slides! Publish all slides and use Windows Explorer.

Publishing all slides to an empty folder creates as many presentations as slides you have. Each new presentation stands for one slide and its Windows Explorer file size shows you which slide has the biggest pictures/audio/video.

enter image description here

In my sample I had 3 slides with different kinds of media. And the first slide with 12 MB was indeed the biggest one.

  • 3 One caveat: Suppose you have a large image on slide 1 and you've copied it to several other slides. PowerPoint only stores the image once per presentation, but if you publish to multiple presentations, each presentation that includes this image would get a copy of it. It'd look quite large, but deleting it from the original presentation wouldn't have nearly such a large effect on overall size. –  Steve Rindsberg Commented Apr 6, 2014 at 15:33
  • 4 Another caveat - the names of the slides are "slide IDs" which are not the same as the slide numbers. If you've copied or reordered slides it could get confusing. –  Rob I Commented Jul 16, 2015 at 15:51
  • 4 Another caveat - the Publish option requires a Professional version of PowerPoint. –  Mark Cramer Commented Dec 2, 2015 at 19:52
  • @SteveRindsberg: Your comment that PowerPoint stores only a single copy of a reused image is indeed correct. However, would that reused image need to be copied over if each slide is made into its own presentation using the technique shown here? Presentation_002.pptx would need its own copy of the image, since it is now a standalone, one-slide presentation on its own without any way to reference copied images from other slides, would it not? –  JeffFerguson Commented Mar 23, 2016 at 20:48
  • When you save/export a slide/slides, PPT takes care of the accounting for reused images. That is, if the slide references a reused image, the standalone version of the slide will get a copy of the image. That's why I mentioned that the size might be misleading. –  Steve Rindsberg Commented Mar 24, 2016 at 3:44

This might depend on the specific version of PowerPoint, but in the version I'm using it is possible to save the presentation as 'Strict Open XML Presentation' file type, which is essentially a zip file with all the elements represented as files within the archive (in some cases this would actually be the default, so no need to 'save as'). So, one can rename the file from .pptx to .zip, open it, and see the sizes of the different element (as well as compression ratio). A good candidate place would be to look under ppt/media. Besides just large images (which can be then easily found and compressed or modified/removed within PowerPoint), in some cases it may contain images from unused master slides, and you may not even know they exist (especially if you are reusing presentations based on someone else's templates). In this case the way to handle it would be to open View -> Slide Master, and browse the master slides to find the one comprising the pictures (and potentially just delete it, if it is not used by any of the slides).

  • 1 Just a note to duplicate the file before you rename it and go digging so you have a solid backup. Also on the Mac you can open a .pptx with something like The Unarchiver (free) directly and it will expand it into the package contents without requiring renaming first. –  Matt Sanders Commented Jul 18, 2018 at 21:56

The easiest way in the latest Powerpoint 365 or any other version is: Save a copy of your presentation with ending PPTX. Rename the ending to .ZIP Unzip the file, and you will see all individual content. Your pictures will be in the folder under the directory ppt/media. Usually, I found PNG files to be largest, so avoid them. sort your files by size, and convert the largest to jpg. Then remove your original pictures in the PPT file and use the jpg files to replace them.

To make your slide deck smaller, quickly, try PowerPoint > File > Compress Pictures. This process just reduced a Mac PowerPoint file (version 16.11) that's photography-heavy from 40MB to 14MB with no degradation in presentation quality.

  • 2 Welcome to Super User! This doesn't answer the question which OP asked, which is about determining the sizes of images, not necessarily compressing them. –  bertieb Commented Apr 4, 2018 at 15:15
  • This is related enough that I think it is reasonable to retain as an answer. The main reason that most people want to know image size is to optimize or remove those images. For some users this capability will be adequate to meet their needs without them needing to identify the individual culprits. –  Matt Sanders Commented Jul 18, 2018 at 22:00

I wrote a small UNIX script that will unzip a pptx file and then shows you the list of larger images (over 100K) sorted by size. It will also have an "open" command (on the Mac) and it will tell you what slides each of the large images are in.

I'm using Powerpoint 365 and I really, really miss the publish slides feature. The zip instructions in this thread didn't work for me but gave me and idea that worked which was using the 'Package Presentation for CD' feature. Open your PPT, go to Export, Package Presentation for CD, Package for CD, change name if you need to, PPT name should be selected in box, hit Copy to Folder, choose where to save files and remember location, hit OK, hit Yes for linked items. Go to your new set of folders, unzip/extract the zip file, and there should be one with all of your images which you can view by details and sort by file size. My path: PresentationCD\PPT_Name\ppt\media

Reduce the file size of your PowerPoint presentations

If the file size of your presentation is too large, try the following tips to make it more manageable.

Compress pictures in your presentation

Select a picture in your document. The Picture Format tab appears.

On the Picture Format tab, in the Adjust group, select Compress Pictures .

Under Compression options , do any of the following:

Make sure that Apply only to this picture is not selected so that the changes you make here will apply to all pictures in the document.

Select Delete cropped areas of pictures . This option removes the cropped picture data but note that if you delete the cropped picture data, you won't be able to restore it.

Under Resolution , select Use default resolution .

Compress Pictures

Under Compression options , do either of the following:

Select Delete cropped areas of pictures . This option removes the cropped picture data but note that if you delete the cropped picture data, you won't be able to restore it.

Compress Pictures options

Delete image editing data and lower default resolution

By default, when you edit an image, the data from the original is retained (to ensure the image can be restored). Discarding it means that you can't restore the changes you make, but it will reduce your file size. Lowering the default resolution for images also reduces your overall file size.

Go to File > Options > Advanced .

Under Image Size and Quality , do the following:

Select Discard editing data . This option removes stored data that's used to restore the image to its original state after it's been edited. Note that if you discard editing data, you won't be able to restore the image after you edit it.

Make sure that Do not compress images in file is not selected.

Set the image size and quality

Reduce the character set of embedded fonts

To make your presentation more sharable with others who don't have the same fonts in their system, it's typical to embed the fonts you use. However, embedded fonts will increase your file size. To minimize the file increase, embed only those characters used in the presentation.

Go to File > Options > Save .

Embed fonts in the file

Note:  If you've used custom fonts and want others to edit the presentation, select Embed all characters .

Reduce the file size of your Word documents

How to Make a “Good” Presentation “Great”

  • Guy Kawasaki

presentation powerpoint slide size

Remember: Less is more.

A strong presentation is so much more than information pasted onto a series of slides with fancy backgrounds. Whether you’re pitching an idea, reporting market research, or sharing something else, a great presentation can give you a competitive advantage, and be a powerful tool when aiming to persuade, educate, or inspire others. Here are some unique elements that make a presentation stand out.

  • Fonts: Sans Serif fonts such as Helvetica or Arial are preferred for their clean lines, which make them easy to digest at various sizes and distances. Limit the number of font styles to two: one for headings and another for body text, to avoid visual confusion or distractions.
  • Colors: Colors can evoke emotions and highlight critical points, but their overuse can lead to a cluttered and confusing presentation. A limited palette of two to three main colors, complemented by a simple background, can help you draw attention to key elements without overwhelming the audience.
  • Pictures: Pictures can communicate complex ideas quickly and memorably but choosing the right images is key. Images or pictures should be big (perhaps 20-25% of the page), bold, and have a clear purpose that complements the slide’s text.
  • Layout: Don’t overcrowd your slides with too much information. When in doubt, adhere to the principle of simplicity, and aim for a clean and uncluttered layout with plenty of white space around text and images. Think phrases and bullets, not sentences.

As an intern or early career professional, chances are that you’ll be tasked with making or giving a presentation in the near future. Whether you’re pitching an idea, reporting market research, or sharing something else, a great presentation can give you a competitive advantage, and be a powerful tool when aiming to persuade, educate, or inspire others.

How many slides does your presentation need?

When you’re creating a presentation, it’s important to consider the amount of information you’re sharing with your audience. You don’t want to overwhelm them, but you also want to be comprehensive and ensure that you’re covering all your bases. Whether you’re giving a 10, 15, or 30-minute presentation, see how many slides your presentation needs to get your point across.

Rules and guidance for PowerPoint presentations

PowerPoint is a powerful visual aid for introducing data, statistics, and new concepts to any audience. In PowerPoint, you can create as many slides as you want—which might sound tempting at first. But length doesn’t always guarantee a successful presentation . Most presentations last around 10-15 minutes, and anything longer than that (such as a 30-minute presentation) may have additional visual aids or speakers to enhance your message.

A handy rule to keep in mind is to spend about 1-2 minutes on each slide. This will give you ample time to convey your message, let data sink in, and allow you to memorize your presentation . When you limit each slide to this length of time, you also need to be selective about how much information you put on each slide and avoid overloading your audience.

For 10-minute presentations

Ten minutes is usually considered the shortest amount of time you need for a successful presentation. For a shorter 10-minute presentation, you’ll need to be selective with your content. Limit your slide count to approximately 7 to 10 slides.

For 15-minute presentations

When preparing for a 15-minute presentation, concise and focused content is key. Aim for around 10 to 15 slides to maintain a good pace, which will fit with the 1-2 minute per slide rule.

For 30-minute presentations

A longer presentation gives you more room to delve deeper into your topic. But to maintain audience engagement, you’ll need to add interactivity , audience participation, and elements like animations . Aim for around 20 to 30 slides, allowing for a balanced distribution of content without overwhelming your audience.

Powerpoint empowers you to develop well-designed content across all your devices

Using the 10-20-30 rule

The 10-20-30 rule is an effective way to structure your presentation. It calls for no more than 10 slides and no longer than 20 minutes (as well as a 30-point font).

Tips for crafting an effective presentation

No matter how long a presentation is, there are guidelines for crafting one to enhance understanding and retention. Keep these tips in mind when creating your PowerPoint masterpiece:

  • Avoid overload: Ensure that each slide communicates a single idea clearly, avoiding cluttered layouts or excessive text.
  • Pay attention to structure: Think of slides as bullet points with introductions, endings, and deep dives within each subject.
  • Add visual appeal: Incorporate images, charts, and graphics to convey information without using too many words to make your audience read.
  • Engage with your audience: Encourage interaction through questions, polls, or storytelling techniques to keep your audience actively involved.
  • Put in the practice: Familiarize yourself with your slides and practice your delivery to refine your timing and confidence.

Ultimately, the ideal number of slides for your presentation depends on the allocated time frame and how detailed your content is. By striking a balance between informative content and engaging delivery, you can create a compelling presentation that can teach your audience something new.
