The 10 1/2 inch square features easy-to-read black and white markings printed in 1 inch grids marked in 1/8 inch and 1/4 inch increments.

Use the easy-to-read, numerical black numbers (printed on white dots) and the 1/4 inch grip sides to cut whole inches. A 45 degree angle is printed in black. White horizontal and vertical lines are printed on the square so the centre of the ruler is easily distinguishable.
