Choose the paper in your printer

Print at Actual size or 100%. The horizontal mark should measure exactly 100 mm, and the square should measure exactly one inch on every side.

If the measurement is wrong

Confirm that Fit to page, Shrink and Scale to fit are off. Some printer drivers apply their own scaling after the browser or PDF viewer. The file can contain exact dimensions while the physical printer changes them.
