what is the size of a license plate?
In 1956, all North American passenger vehicle licence plates, except for French-controlled St. Pierre and Miquelon, were standardized at a size of 6 in Ã 12 in (152.40 mm Ã 304.80 mm), although a smaller size is used for certain vehicle classes, such as motorcycles, and for the state of Delaware's historic alternate black and white plates, which are 5.25 in Ã 9.5 in (133.35 mm Ã 241.30 mm).
