Number Plate Maker UK: Road Legal 3D & 4D Plates, Starting From £15
Legal & Show Plates is an online number plate maker based in Bradford, building road legal and show number plates to order. Every road legal plate is made to BS AU 145e, the British Standard that governs character size, spacing, font and reflectivity, so what you design in the builder is a plate that is legal to fit and drive on. Standard plates start from £15, with 3D gel, 4D, 5D gel and Black Diamond finishes above that. Order before 2pm and most plates are dispatched the same day, with free delivery on orders over £30.
If you already know what you want, the number plate maker is the fastest way to get there. If you are still deciding between styles, the guide below covers what each one actually looks and feels like, who it suits, and where the legal line sits between a road plate and a show plate.
Why buyers choose Legal & Show Plates
A few things that are true about how we work, rather than a list of adjectives:
- Made to BS AU 145e. Road legal plates are manufactured to the current British Standard for character height, width, stroke and spacing, the same spec DVSA and the police check against. Read what that actually covers on our compliance page.
- Same day dispatch. Orders placed before 2pm on a working day are usually dispatched that day. You can read the full cut-off times and courier details on our delivery and returns page.
- Free delivery over £30. No minimum order size, just a straightforward threshold.
- Built and finished in Bradford. Plates are made at our workshop rather than drop shipped. More on how we work on our about us page.
- Reviewed by real customers. See what people have actually said on our reviews page, and a few examples further down this page.
Number plate prices
Prices below are per single plate. Most cars need a pair, front and rear, and the builder totals this automatically once you choose your quantity and style.
| Style | Starting From |
|---|---|
| Standard | £15 |
| 3D Gel | £20 |
| 4D, 3mm | £20 |
| 4D, 5mm | £26 |
| 4D Gel | £28 |
| 5D Gel | £33 |
| Black Diamond | £30 |
Choose your plate style
Seven finishes, all made to the same 520mm x 111mm plate size. The difference is in how the characters are formed and how they catch the light.
Standard plates
Flat, printed characters on a reflective base. The plate most cars are fitted with from the factory, and the most budget friendly option here. A sound, fully compliant choice if you want a clean factory look rather than a raised finish. Full detail on the standard number plates page.
3D gel plates
Characters are built up with a resin gel that sits proud of the plate, giving a rounded, glossy edge that catches headlights and camera flashes. A popular middle ground between a subtle factory look and a fuller show finish. More on the 3D gel plates page, including which cars suit it and what to check before you order.
4D plates
Laser cut acrylic characters bonded to the plate, available in 3mm or 5mm depth. The thicker 5mm option throws a stronger shadow and reads as more premium in photos, particularly on darker cars. Compare the two on the 4D plates page, or go straight to 4D 3mm or 4D 5mm.
4D gel and 5D gel plates
4D gel combines the laser cut depth of 4D with a domed gel finish over the top. 5D gel goes further again, the deepest, glossiest finish we make. Both suit buyers who want their plate to be the first thing people notice. Details on 4D gel and 5D gel.
Black Diamond plates
Our most distinctive finish, a dark, faceted background with the character contrast still meeting the legal standard. Suits performance and luxury cars where the driver wants something that does not look like every other plate on the road. Full detail on the Black Diamond page.
Not sure which of these fits your car? 3D vs 4D, which one should you actually buy and the best number plates for black, white and silver cars both go into more depth than we can fit here.
How the number plate maker works
You choose a style, type in your registration, and the builder shows you a live preview as you go, so you can check spacing and layout before you pay rather than after. It will stop you from creating a plate that breaks the legal spacing or font rules if you are ordering a road legal plate, and it will flag when a layout is only available as a show plate.
- Pick a plate type. Front, rear, or both, and whether you need a road legal or show layout.
- Choose your finish. Standard, 3D gel, 4D, 4D gel, 5D gel or Black Diamond.
- Enter your registration. The preview updates instantly, so you can see spacing and sizing before you commit.
- Add any extras. Badges, borders or a colour badge where the style allows it, without breaking the legal contrast rules on a road plate.
- Check, then order. Review the preview one more time against your actual registration document before paying, this is the single step that prevents most reprints.

Is our number plate builder right for you?
This works well for you if you drive a UK registered vehicle and want plates made to your exact registration and chosen finish, whether that is a straightforward Standard replacement or a Black Diamond finish for a car you want to stand out. It also works well if you want display only show plates for events, a garage build, or a vehicle that never goes on the road.
It is not the right fit if your vehicle is not registered in the UK, since our road legal plates are built to the UK's BS AU 145e specification rather than another country's standard. It is also not the right choice if you are looking for a way around the legal spacing or font rules on a car you drive, the builder will not let you create a road legal plate outside those limits, and nothing we make is designed to help a plate avoid ANPR or camera systems.

Road legal or show, know the difference before you order
This is the single most important decision on the page, and it is worth getting right before you design anything. A road legal plate has to meet BS AU 145e on character size, spacing, font and reflectivity, and it has to carry your correct, current registration exactly as issued. A show plate can use styling, spacing or lettering that a road legal plate cannot, but it is for display only, at events, in a garage, or on a vehicle that never goes on a public road. Fitting a show plate to a car you drive is an offence, full stop, regardless of how good it looks.
If you are ordering for a car you actually drive, start on the road legal number plates page. If you want something for display, our show plates page explains exactly what is and is not allowed. For the technical detail behind the standard itself, see our compliance page and the articles on what BS AU 145e actually specifies and spacing rules explained.
Which plate suits your car
Colour and finish. Raised finishes like 4D and gel show up more clearly against dark paintwork, the shadow the raised character casts is what does the work. On white or silver cars, a flatter finish like Standard or 3D gel often reads more cleanly, since there is less paintwork behind the plate to compete with. Our article on the best number plates for black, white and silver cars goes through this car by car.
Performance and luxury cars. These are where 5D gel and Black Diamond get chosen most, buyers want the plate to match the rest of the car rather than look like an afterthought.
Daily drivers. Standard or 3D gel tends to suit cars used every day, where a subtler finish that still looks sharp matters more than maximum depth.
Electric vehicles and colour coded plates. If your vehicle qualifies for a green flash or you want a colour matched finish, see our colour badged number plates page for what is available and what still has to stay within the legal spec.
Private and personalised registrations. If you are putting a private or cherished registration onto physical plates for the first time, start with our private number plates page, which covers the documents you will need and how the process differs from ordering with a standard registration. There is more background in private number plates explained.
Before you order: common mistakes worth avoiding
- Ordering before measuring. Bumper recesses and plate surrounds vary between models and even between trim levels of the same car. If you are unsure, check the fit before you order rather than after.
- Typing the registration in wrong. Characters that look similar (an O and a 0, an I and a 1) are the most common cause of a plate coming back wrong. The builder preview exists so you can catch this before you pay.
- Assuming any spacing is fine. Rearranged spacing to spell a word or phrase is one of the most common ways a plate fails the legal standard. Our spacing rules guide covers exactly what is and is not allowed.
- Not knowing what can cause an MOT problem. A plate that is the wrong font, poorly spaced, or hard to read at distance can be flagged. See what causes an MOT failure on number plates.
For a longer list, our article on the top mistakes people make when ordering number plates is worth five minutes before you start designing.
Fitting, care and delivery
Every plate comes with fitting guidance, and our fitting guide covers screws versus pads, and what to do if your bumper will not take a self tapping screw. Once fitted, raised finishes like 4D and gel need a slightly gentler approach to cleaning than a flat plate, covered in our plate cleaning and maintenance guide. For dispatch times, courier details and our returns policy, see delivery and returns. If a plate is ever damaged or comes loose, our article on what to do if your number plate falls off or gets damaged covers your options, including our replacement number plates page if you need a new one made.
From the workshop
Staff experience, from the team that makes and checks your plates before they go out.
The most common thing we catch before dispatch is a registration typed with the wrong character, where an O and a 0, or an I and a 1, look near identical on screen but read differently once printed. That is why the builder preview matters, and why it is worth checking your plate against your actual V5C or registration document one more time before you pay, not just the number in your head.
On fitting, the most common issue customers report back is sticky pads not holding on a cold or damp day, or on a textured bumper. Screws give a more reliable fix on most cars where the mounting holes allow it, pads work better on smooth, flat panels in normal weather. Our fitting guide covers both.
On finish choice, raised finishes like 4D and gel do add a small amount of thickness to the plate. On most cars this is not noticeable, but if your bumper recess is unusually shallow it is worth checking before ordering a deeper finish like 5D gel.
Replacement and private plates
If you already have a set of plates and need a new one made, whether it is damaged, faded, or you have just bought a private registration, our replacement number plates page covers what you need. For putting a private or cherished registration onto plates for the first time, see private number plates and personal number plates.
