I mean the margins as in how much space around the edges of the page. Right now it looks like there is about 36 points on all four side of the page surrounding the content. When you create a new PDF from a blank page your can control the margins either before you create the page in Preferences or after the page has been created. Often times I like to have a slightly larger margin on the left side pages so I can three hole punch them to place in a binder with out punching into the content. Does that make sense?
