4D Number Plates (5mm Depth)
Understanding 4D 5mm Number Plates
This guide provides detailed information about 4D number plates with a 5mm character depth, a popular option for vehicle owners looking to enhance their vehicle's appearance while adhering to legal standards.
What Defines a 4D 5mm Number Plate?
4D number plates are distinguished by their raised characters. The "5mm" specifically refers to the thickness of the laser-cut acrylic characters which are bonded to the plate surface. This construction creates a prominent, three-dimensional effect.
Key Features and Construction:
- Character Depth and Material: Characters are precisely laser-cut from 5mm thick acrylic, offering a distinct, raised profile. This process ensures sharp, well-defined edges for each letter and number.
- Manufacturing Process: Advanced laser-cutting technology is employed to produce the characters, ensuring accuracy and consistency. These are then applied to a British Standard 145e compliant reflective backing plate.
- Sizing and Customisation:
- Standard UK Size: The default dimensions are 520mm x 111mm, suitable for most vehicles.
- Shortened Plates: Plates can be custom-cut to a shorter length, depending on the registration number. A 16mm margin is typically maintained around the registration for a balanced look.
- Hexagonal Plates: An alternative shape, often chosen for specific vehicle aesthetics, can also be sized according to the registration.
- Legal Compliance (UK):
- DVLA Conformation: 4D style plates, including those with 5mm raised characters, are considered legal for road use in the UK, falling under the regulations for 3D (raised character) plates.
- Font and Spacing: All plates are produced using the mandatory Charles Wright font and adhere to correct spacing requirements.
- Manufacturer Details: Plates include the manufacturer's name (Utopia Plates) and postcode, as legally required.
- British Standard: Plates are certified to BS AU 145e, the current UK standard for number plates, indicating they meet requirements for durability, reflectiveness, and visibility.

Please note that by law we include our company name, postcode and BSAU number on the plate. The font style for all our plates is Charles Wright which is the legal UK road font, compliant with the law. The DVLA confirm that three-dimensional characters are legal and compliant with road laws, this includes ‘4D’ number plates, as 4D is only an industry standard name, and they are still classed as three-dimensional.
When buying number plates online, the only way to operate fully legally is for the Registered Number Plate Supplier to see the original physical documents in person. If you aren't local to us in County Durham, you will need to send us the documents in the post. The process is simple and the steps to take are explained in depth after you have placed your order. Once we have received your documents, we will produce your number plates and return the documents securely along with the number plates, using a tracked postal service.
The standard UK size for number plates are 520mm by 111mm. Please note this will vary if you opt for a shortened plate option. Shortened plates are cut down to a unique size depending on the length of your registration. Unlike our competitors, we cut these to whichever size you require rather than using pre-made short plates. We produce them to have a 16mm margin on all edges of the number plate, which leaves a nice even clean finish to your plate. If you require a specific size, please state this in the special requests box after clicking purchase. Legally, your number plates cannot have a margin any less than 11mm.
Utopia Plates does not sell show plates, as they could be used on the road, even though the manufacturer may sell them on the basis that they will not be. To avoid this, we will not sell show plates (this includes tinted plates, blank plates or those with non-standard spacing). We will only produce fully road legal plates, with standard spacing (as it appears on your V5C).
