To open the Page Setup screen:
- Go to File.
- Select Page setup.
To change your page orientation in Google Docs to "Landscape":
- Select Landscape.
- Click OK.
Optional: If you are using landscape mode most of the time, you can always Set as default, so you don't have to change it every time.
You can vary portrait orientation and landscape orientation multiple times on each page of your Google Doc. To make a portion of a page landscape or portrait:
- Highlight the portion of the page you want to change.
- Right-click on the highlighted portion.
- Choose Change page to landscape.
To stop the orientation at any point on a page, highlight where you want the orientation to change back, and follow the above steps, choosing Change page to portrait.
