What Size Are Motorbike Number Plates?
The standard size for a UK motorbike number plate is 228mm x 178mm (9 x 7 inches). This is the size that fits the majority of modern motorcycles, scooters and mopeds registered in the UK.
Unlike car plates which display characters on a single line, motorcycle number plates must show the registration on two lines, with the age identifier on top and the random letters below. Single-line motorbike plates are not legal.
The exact minimum size of your plate depends on the length of your registration mark. Shorter registrations allow for narrower plates, provided the required margins around the characters are maintained. If you are unsure, our plate builder will calculate the correct dimensions automatically based on the registration you enter.
