This 1" x 12" rectangle ruler features black, easy-to-read markings printed in 1" grids. Additional markings are made in 1/8" and 1/4" increments along the ruler, and dashed lines are printed 1/4" away from both edges to aid in trimming seam allowances. The 1/2" line is also clearly defined through the center of the ruler, making measuring and cutting a breeze - no matter the project.
