I am trying to open a new Document in Adobe In Design. In the fields that allows you to change the size to what I want it willl not allow me to. I want to open a new document 12 in x 12 in. It seems to be stuck on 51pO x 66po and all the margins say 3 p0. I have no idea what they even mean. I have a window open and am watching a video on how to and the guy has no trouble changing the size and margins but I can not. Don't know where to go from here.
Moved from the Creative Cloud to the InDesign forum. They will be able to help you here.
I don't even know how to do that seem like I am in In Design
What you are seeing are the defaults in picas. If you type in 12in in the width field and 12in in the height field you'll get your 12x12 document.
If you open your preferences and change the units to inches beforehand you'll see inches as the default.
