1/4 Inch Graph Paper

Every fourth line is a full inch in disguise. For any drawing where inches matter. Circuit board layouts, hand-cut templates, sewing patterns. Work to the every-fourth-line rhythm and you have a precise inch ruler built into your sketch.

Quad ruled lacks accent lines by default. For data plots, lightly trace over every fifth or tenth line with a ruler before plotting. It gives you the visual anchor of engineering paper without printing on a different template.

Bold every fifth line by hand
