How to change ONE page in Google Docs to landscape
There’s no doubt that portrait orientation is the way to view the vast majority of documents on the web. It’s how we’ve always read books and visited websites. You’re reading this post in portrait orientation, right?
In the edge cases where you need to make a document wider than it is tall, you can use Google Docs. Whether you are making a presentation slide, poster, or something similar, setting up your document this way is just a few clicks away.
To begin formatting your document in landscape orientation, click the File menu option, then click Page Setup… from the expanded menu.
