Sizing Guide

Choose your plate size

Choose the right size for your vehicle and registration. Standard UK plates suit most vehicles, while short plates and hex plates offer more compact options where the registration allows.

What size number plate do I need?

Most vehicles use standard UK number plates. These are the default road legal size and the correct choice for the majority of registrations. If you have a shorter registration, you may be able to use a shorter plate format while still remaining compliant. If you want a more distinctive finish, hex plates offer a shaped alternative when built to the correct specification.

Standard plates

Best for most vehicles and standard UK registrations.

Short plates

Ideal for shorter registrations and a tighter overall fit.

Hex plates

Shaped plates for a bolder finish, built properly for road use.

Are all number plate sizes road legal?

Size alone does not make a plate legal or illegal. What matters is whether the finished plate still follows the correct UK rules on spacing, layout, readability, materials and overall construction. You can learn more in our road legal number plates guide and number plate law explained page.
