I apologize this isn't 'art & craft' of fantasy writing, but I was wondering what page format you guys use in your word processors? I was fidgeting with a few word processors, WPS, Office, Openoffice...and found the page formatting section and I was using one called A4 as opposed to Letter. I thought it was like the size of a paperback but I'm not sure. I want to write in a format that is close to a traditional fantasy paperback as a time reference.
