Graph paper size comparison
5 mm and 1/4 inch look almost identical in a thumbnail and are 21 % apart on paper. Put the sizes you are torn between side by side, see the actual squares, and check how many fit on a sheet before you download.
Compare up to four sizes
Every preview is the real sheet geometry at the same zoom — so the size difference you see is the size difference you get.

Still torn? Print one sheet of each at Actual Size and hold them together. The bars at the bottom confirm both are true to size, then you can compare for real.
