A quilting ruler is square or rectangular in shape and has first, second, third and fourth edges with a first set of equally spaced rulings running parallel to the first and third edges of the ruler and at right angles to a second set of equally spaced rulings running parallel to the second and fourth edges of the ruler. The first line of the first set of rulings is spaced from the first edge of the ruler by a different interval from the interval by which the last line of that set of rulings is spaced from the third edge of the ruler, and the distance of each line of the first set of rulings from the first edge and of each line of the second set of rulings from the second edge is marked so as to be visible when the first and second edges of the ruler are in use and the distance of each line of the first set of rulings from the third edge and of each line of the second set of rulings from the fourth edge is marked so as to be visible when the third and fourth edges of the ruler are in use.
