Page Layout Tool is a free add-on for setting the page layout in Google Docs. It is able to set the page’s size and margins. I made the add-on after running being frustrated that I was not able to set the Google Doc page size to any value I wanted. So, one of the key features of Page Layout Tool is that you can choose a custom page size.
In addition to being able to choose a custom size, I have also added a more comprehensive set of pre-defined options, including 3.5" x 5", 4" x 6", 5" x 8", A3, A4, A5, B4, B5, Letter, Tabloid, Legal, Statement, Executive, and Folio.
If you have any questions or requests, feel free to contact me below.
It isn't doing anything!
Page Layout Tool can be a little slow on large documents. Trying changing the size, clicking "set", and then waiting 60 seconds without touching anything. If you start clicking around you might stop the process and it won't work.
