What Are Hex & Diamond Number Plates?
Hex and diamond number plates are uniquely shaped plates cut into hexagonal or diamond forms — a striking departure from the standard rectangular plate. Their bold geometric shapes make them an eye-catching feature for any car, garage wall, or display stand.
These plates are popular in the custom car, motorsport, and show car communities. They can be made with any registration, name, or custom text, and are available in a range of colours, finishes, and character styles — from standard yellow and white to full colour designs.
Our hex and diamond plates are manufactured in the UK to the same high standard as all our plates — cut precisely, finished professionally, and delivered fast.

Are Hex Plates Road Legal?
Hex and diamond plates are not road legal — they do not conform to the standard rectangular dimensions required by UK law (BS AU 145e). They are intended purely for display purposes.
That said, they are completely legal to own and display in your garage, on a show car, at an event, or as a wall display. Many customers order them alongside their standard road-legal plates as a matching display piece.
Tip: Perfect for garages, mancaves, show stands, and car events. Display your registration in style without putting non-compliant plates on the road.

Frequently Asked Questions
Everything you need to know about hex and diamond number plates.
What is the difference between a hex plate and a diamond plate?
A hex plate is cut into a regular hexagonal shape (six equal sides), while a diamond plate is cut into a four-pointed diamond or rhombus shape. Both are popular choices for show displays and custom vehicles. The shape is purely aesthetic — the registration text is printed in the centre of each shape in the standard Charles Wright font.
Can I use a hex or diamond plate on my car on the road?
No. Hex and diamond plates are not road legal as they do not conform to the rectangular dimensions required under UK legislation (Road Vehicles (Display of Registration Marks) Regulations 2001 and BS AU 145e). They are intended for display purposes only — garages, shows, and events. You must continue to display compliant standard plates on your vehicle when on public roads.
Can I put any text I like on a hex or diamond plate?
Yes — since hex and diamond plates are show plates (not road-legal plates), you can put any text, name, or custom message on them. They are popular as personalised gifts, car show displays, garage decorations, and man-cave décor. You don't need to use a real vehicle registration number.
Do you offer 3D or 4D characters on hex plates?
Yes. You can choose from our standard flat print, 3D domed gel characters, or 4D laser-cut acrylic characters on hex and diamond plate shapes. The 3D and 4D options add an impressive raised effect that looks stunning for display purposes.
How long does delivery take?
Standard delivery typically takes 2–4 working days. We also offer express and next day delivery options if you need your plates quickly. All delivery options and their current prices are shown at checkout.
What sizes are hex and diamond plates available in?
Our builder offers a range of size options suitable for different display purposes. The available sizes are shown in the plate builder above — simply configure your plate and the available sizes will be presented for selection.
Can I get a hex plate as a gift?
Absolutely — hex and diamond plates make excellent personalised gifts for car enthusiasts. You can use their name, favourite car registration, or any meaningful text. They're a unique, premium gift that's completely custom-made to order.
