If you’re not satisfied with the Standard or Widescreen options, you can customize the size of the slides even further by selecting the Page Setup option.

In Page Setup, you have the option to select a custom length and width for your slide as well as alter the orientation. If you’d prefer to use one of the preset sizing options, you can see which ones are available by clicking the drop-down menu where it says Widescreen.
