What Size Is a Car License Plate?
What size is a car license plate? The most common size is 12 inches by six inches, and in some states, these measurements vary slightly. In Maryland, the license plate size is four-and-a-half inches, or 110 by 180 millimeters. Puerto Rico also issues European-size plates, although they cost extra. In other states, however, there are no official standards. Therefore, if you're unsure of the proper size, we recommend that you ask your local bureau of motor vehicles for guidance.
