About this paper
Brick graph paper
Each row (course) is a strip of rectangles, and every other row is shifted by half a brick so the vertical joints never line up. The spacing sets the brick height and the width ÷ height ratio sets its length.
A ratio of 2 gives the look of many pavers and subway tiles. Use 3 for modular brick proportions including mortar joints, or about 1.2 for brick stitch beadwork with cylinder beads.
