1mm graph paper has to print at true size

A printer that shrinks the page by a few percent spoils a millimeter ruling. Print at 100%, then lay a ruler on the sheet: ten heavy centimeter squares should measure 10 centimeters. The A4 sheet holds 180 by 270 squares, 18 by 27 cm.

Which sheet to pick

One sheet keeps the heavy centimeter lines and drops the 5 mm lines. The plain grid has every line the same weight. The numbered sheet counts millimeters from the corner: 0, 10, 20. The 2 mm sheets have a heavy line every 1 or 2 centimeters.

Before you photocopy a sheet, open More options and set Line color to Black, for a copier.
