The Creative Grids Quilt Ruler measures 2-1/2 inches wide by 24-1/2 inches wide. This ruler was designed to fit the width of a standard size cutting mat with no overhang, making it perfect for cutting directly off a fabric bolt. The Quilter's Ruler features black and white guidelines printed in 1 inch increments with 1/8th and 1/4th inch guide markings in between. Creative Grids rulers slide easily over fabric but stay firmly in place when pressure is applied. Made in the USA!
