Standard Replacement Number Plates
Standard Number Plates
Our Standard Number Plates are manufactured using premium reflective materials to meet UK road-legal requirements. A durable, high-quality finish makes them the perfect choice for everyday driving and replacement plates, and at £25 a pair, they're also the plate most UK cars are actually supposed to be wearing from the factory.
There's no raised acrylic, no gel dome, no diamond-cut facet catching the light on a Standard Number Plate. What you get instead is a flat, correctly spaced, retroreflective plate built to British Standard BS AU 145e: the same standard every plate in our range is built from, whether that's this one or Black Diamond at the top of the range. If you've landed on this page because a plate got cracked in a car park, went missing off the back of a van, or came with a used car looking tired and yellowed, a Standard Number Plate is almost certainly the one you actually need.
What are Standard Number Plates?
A Standard Number Plate is built from a retroreflective acrylic base, printed with black characters at 79mm tall and 50mm wide (the number 1 and the letter I are narrower, that's normal and correct), with a 14mm stroke width and 11mm gaps between characters. Those figures aren't ours to choose. They're set out in the Road Vehicles (Display of Registration Marks) Regulations and repeated in the DVLA's own INF104 leaflet, and every number plate we cut, from this one up to Black Diamond, starts from the same measurements.
At standard UK size, that's a plate measuring 520mm by 111mm front and rear, the oblong shape almost every car on the road wears. Front plates carry black characters on a white retroreflective background; rear plates carry the same black characters on yellow. That colour split isn't decorative. It's part of what makes a plate legible to a human eye at speed and to an ANPR camera at any time of day, and it's identical across every finish we sell, Standard included.
Standard Number Plate specifications, and what they actually mean for you
| Requirement | Figure | What it means in practice |
|---|---|---|
| Character height | 79mm | Every character on the plate, whatever the finish, is built to this height first. |
| Character width | 50mm (except the number 1 and letter I) | Narrow letters are intentionally slimmer; that's correct, not a fault. |
| Stroke width | 14mm | The thickness of the printed black line itself. |
| Space between characters | 11mm | Checked closely on personalised registrations where owners sometimes try to squeeze spacing to change how the reg reads. |
| Space between the age identifier and random letters | 33mm | For example, the gap between "24" and "ABC" on a 24-plate registration. |
| Plate size | 520mm x 111mm (front and rear) | The standard UK oblong size almost every car is fitted with from new. |
| Front plate colour | Black characters on white, retroreflective | |
| Rear plate colour | Black characters on yellow, retroreflective | |
| Character colour | Single, solid black | No two-tone or gradient effects on the character face; this is the rule that actually restricts styling, not the presence of a raised or gel finish. |
| Supplier marking | Manufacturer name and postcode, 3-10mm tall | Positioned below the characters on every plate we dispatch. |
| Standard | BS AU 145e | Mandatory for anything supplied or fitted since 1 September 2021. |
What that table actually buys you: a plate that an MOT tester, a police officer and an ANPR camera all read the same way, because none of those three things care about depth or gloss, they care about contrast, spacing and colour. A Standard Number Plate has the fewest variables between "cut" and "reads correctly" of anything we sell, which is a large part of why it's the default fitted to most cars in the UK.
How much do Standard Number Plates cost?
A pair of Standard Number Plates is £25, or £12.50 for a single plate, confirmed at checkout and shown as the first option in our plate builder. That makes Standard the cheapest style in our range, £13 less than 3D Gel, £13 less than 4D (3mm), and £39 less than 5D Gel, our flagship finish.
Set against the cost of getting it wrong, that £25 looks like better value still. A non-compliant plate can fail an MOT outright, and the police can issue a fine of up to £1,000 for one that doesn't meet the display regulations. That's not scaremongering, it's simply what the rules allow for, and it's why buying from a supplier who actually builds to BS AU 145e matters more than the small price difference to a market stall or an uncertified online seller.
Badge and border customisation, available at the same builder step where you choose your plate style, don't add to that £25 price. You're paying for the plate, not for the option to add a flag or a coloured border to it.
