To change slide dimensions in Google Slides, open your presentation, click File > Page setup, and open the size menu. Choose Standard 4:3, Widescreen 16:9, or Widescreen 16:10, or pick Custom and enter your own width and height in inches, centimeters, points, or pixels. Click Apply. The new size applies to every slide in the presentation.

Fix content after resizing
Google Slides scales your content to fit the new size, which can stretch or shrink text and images.
- Resize before adding content whenever possible.
- Update the theme: Go to Slide > Edit theme and adjust the layout placeholders so new slides fit.
- Reposition items: Select an item and use Arrange > Center on page.
- Keep image proportions: Hold Shift while dragging a corner.
Frequently asked questions
Can different slides have different sizes?
No. Page setup applies to the whole presentation. Use a separate presentation for slides that need a different size.
Can I change the slide size on my phone?
No. The Google Slides app doesn’t have Page setup. Change it on a computer.
What size is best for printing?
Match the slide size to your paper, like 11 x 8.5 inches for US Letter landscape, so nothing gets cut off or shrunk.
Does changing the size affect PowerPoint exports?
Yes. When you download as PowerPoint, the file keeps your slide size.
