A better way to change your slide sizes in PowerPoint.

An easy way to change slide size 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 change slide dimensions for your PowerPoint presentation. We are going to discuss both the standard way (as well as why we don’t recommend it) and the right way, using our PowerPoint resizing tool.

TLDR: If you want to skip the details and go straight to the instructions on how to use our PowerPoint presentation resizing tool to change slide sizes then Click Here.

Why the standard solution does not work:

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 dropdown 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 presentation 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.

METHOD 1: The standard way, to change your slide dimensions (not recommended):

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.

2) then the Slide Master button

3) Click on the Colors dropdown list and then on the
4) Customize Colors… button at the bottom of the list.

At the bottom of the Colors 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.

Step 4: Resize your PowerPoint presentation

After you closed the Slide Master Ribbon the Design Ribbon should be visible again. Click on the Slide Size dropdown 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).

Step 5: Reselect your Theme color and Theme font

With the Design Ribbon still active click the Variants dropdown arrow, 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 Dropdown 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.

  • 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.
