Google has made it easier to create and work with documents that require multiple page orientations in Google Docs.
Starting as soon as December 10, 2020, you will be able to change the page orientation on a per-section basis in a Google doc. This will allow you to make room for wider content such as tables and images that can benefit from extra horizontal space. You’ll also be able to edit, import, and export Microsoft Word documents that contain both portrait and landscape oriented pages.
