Squares per sheet with the default ½ inch margins and the footer line. Every count above is what the generator draws, not an estimate: only whole squares are printed, and the leftover space is split evenly between both margins.
Printing tips
Print at Actual size. "Fit to page" is the most common reason printed graph paper comes out a few percent small; the guide shows how much and how to check. For homework that will be scanned or photocopied, choose Bold lines or the Gray/Black colour; for paper you will write over heavily, Light blue lines stay out of the way.
