How to Change Slide Size in Google Slides on PC

Changing the size of slides in Google Slides on PC is relatively simple. The process includes the following steps:

  1. Go to the Google Slides webpage and open an existing presentation or create a new presentation.
  2. In the menu bar, go to “File”.
  3. Click “Page Setup” to display page options.
    • You will see the Page Setup dialog box with the page size drop-down menu. The default size of Google Slides pages is 16:9.
  4. Click on the drop-down menu and choose the preferred page size. You can also go to the "Custom" option and enter the page dimensions manually. Whichever option you choose, press "Apply" once you have selected the size you want.

One thing you should note about this method is that when choosing the "Custom" size, you need to know the exact size you want. Choose the unit type – such as centimeters, inches, points or pixels – and enter the precise values.



The options in the "Layout" menu have certain limitations. For example, if you want to change your slide size to A3 or A4, these are not offered in the drop-down list. For these page sizes, you will need to choose "Custom" and enter the following values:
