Click on the green + in the upper right corner to start a new project. Here is where we will create our new template for our typesets.
I will rename it “Letter Typeset” with our page size being 5.5x8.5inches.
You will want Multi-page turned on, facing pages arranged horizontally and starting on the right.
For my margins I have mostly been using 0.7in for Inner, 0.8 for everything else. I find this is what I like most for paperbacks. I would say you want a minimum of at least 0.5 inches for hardbacks.
Don’t forget to hit “Create Preset” before you click “create document”
Your new preset will show up on the home page now.
This is what will open when you start a new project now.
