When you open Google Slides, by default, all slides are in the landscape or horizontal orientation. The landscape orientation is the most common setting for presentation screens and projectors. However, in some cases, you may want to change the orientation to portrait mode.
You may want to take advantage of the extra vertical space when the slide is in the portrait mode. Or, your printer or projector supports only that mode. Please note that Google Slides does not allow you to select a specific mode for a single slide—all slides must be in either landscape or portrait mode.
Changing the orientation of Google Slides to portrait mode is fairly simple.
You can also change back to the landscape mode equally easily.
Let us walk you through the steps involved.
