Printable ruler

A 10 inch ruler marked to the sixteenth of an inch and a 25 cm ruler marked to the millimeter, both on one landscape sheet, plus a sheet of smaller 6 inch and 15 cm rulers. The long side of US Letter is 11 inches, so 10 inches is the longest straight ruler it can hold.

A printed ruler is only as good as the print. Each sheet has a 1 inch square to check first, and our guide to printing at actual size explains why a printer might shrink it.
