How to Change Slide Dimensions in Google Slides

The Google Drive suite of applications includes Google Docs, Google Sheets, and Google Slides. The Google Slides program has a variety of options that allow you to customize the way that you want your presentation to look. But if you need to change the slide size in Google Slides, then you may be wondering where to find the page setup menu that will allow you to do so.

If you are creating a presentation in Google Slides, then it’s possible that the current slide dimensions aren’t suited to your needs. Not all presentations require the same design, and you may even need to use custom slide dimensions or an aspect ratio that isn’t available by default. Fortunately this is something that you can change so that your presentation slides appear the way that you need them to.

Our tutorial below will show you where to find the menu that lets you specify the dimensions or aspect ratio of your slides, and even show you how to use the Custom option that lets you get even more specific about the dimensions that you would like to use.

Regardless of which unit of measurement you select, the aspect ratio on the screen will stay similar. However, the slide size in Google Slides and the aspect ratio can have a big impact on how the presentation will fit onto the paper size that you select from the Print menu.

More Information on How to Change the Slide Size in Google Slides

  • The Page Setup menu found under the File menu only includes options for adjusting the slide size. If you need to change other slide settings in Google Slides, then you will need to do so from either the Format tab or on the Print settings and preview menu.
  • The default aspect ratio options in Google Slides are: Standard 4:3, Widescreen 16:9, Widescreen 16:10, and Custom.
  • You can change the slide size or aspect ratio as many times as you want, but each change to this setting can affect existing elements in Google Slides. Be sure to proofread your slideshow after you change aspect ratios or slide sizes.
  • The default slide size in Google Slides is Widescreen 16:9. Using the 16:9 aspect ratio means that your presentation will typically look good on newer computer monitors, as well as many different paper sizes.
  • Much like Google Docs, Google Slides can integrate with its corresponding Microsoft presentation application, Microsoft Powerpoint. Simply choose the Download option from the File menu, then choose the Microsoft Powerpoint (.pptx) download option. If you change the slide size in Google Slides after downloading a Powerpoint presentation file, however, that change won’t apply to the Powerpoint version. You would need to re-download it.
