Number plate spacing is set by the British Standard BS AU 145e and the display regulations, and altering it so the registration reads differently is illegal. Characters must sit in the standard layout with the correct gaps between letters and numbers and between groups, using the legal font. Spacing number plates illegal in this way, whether to form a word or to make characters look like others, can fail an MOT and lead to a fine.

Updated October 2026 · Independent information, not legal advice
Many owners of personalised plates want to make a registration read like a name or word, and that is where the rules bite. This explains what spacing is required, what is not allowed, how it applies to short, older and personalised registrations, and how to get a plate that is both legible and compliant.
What Are The Number Plate Spacing Rules?
The standard sets how far apart characters, groups and margins must be, based on the plate's characters and layout. A current style plate has two letters, two digits, a gap, then three letters, and the gap sits in one fixed position. The characters must be evenly spaced inside each group and must not run together or spread apart.
Where do the rules come from?
From the British Standard BS AU 145e, which the display regulations require for road plates, and from the DVLA's rules on displaying registration marks. Check GOV.UK for the current detail.
What do the rules cover?
- The shape, height, width and stroke of each character.
- The gap between characters in a group.
- The larger gap between groups.
- The margins at the edges of the plate.
Is Spacing Number Plates Illegal?
Spacing number plates illegal questions have a clear answer: yes, if the spacing changes how the registration reads or departs from the standard layout. Moving a gap, squeezing characters together or adding space to split a group can make a plate non-compliant.
| Practice | Legal on the road? | Why |
|---|---|---|
| Standard spacing from a registered supplier | Yes | Follows BS AU 145e |
| Squeezing characters so they merge | No | Changes legibility |
| Moving or hiding the group gap | No | Alters how the registration reads |
| Spreading characters to form a word | No | Departs from standard layout |
| Short plate with correct spacing | Yes, if compliant | See short number plates |
Why Does Spacing Matter?
Who is affected when a plate is misread?
The wrong person can receive a penalty notice, and a vehicle can be mistaken for another. Even a small misreading creates real problems.
Spacing matters because the registration must be readable by people and by automatic cameras. If the layout changes what a person or a camera reads, the plate loses its purpose as an identifier. A vehicle may also be wrongly matched to another registration in the DVLA system.
- Police and parking enforcement read plates by eye.
- Cameras use the layout to read the characters.
- Insurers and the Motor Insurance Database rely on the registration.
- Testers check plates as part of the MOT.
What Is The Legal Gap In A Current Style Plate?
On a current style plate such as AB25 CDE, there is a single standard gap between the age identifier and the three random letters. It must be the standard width, not smaller, not larger and not missing. The age identifier and the memory tag stay together.
Can I remove the gap?
No. The gap is part of the standard layout, and a plate without it is not compliant.
Can I Make A Registration Look Like A Word?
No. Making a registration read like a name or word by changing the spacing or the shapes of characters is not allowed, even if the registration itself is legitimate. The characters must not be altered, styled or spaced so that they look like different characters. This is the most common reason personalised plates fail.
Why do people try it?
Because a personalised number plate is bought for the way it reads. The lawful way to get a registration that reads well is to choose the registration, not to reshape it.
What About Letters That Look Like Numbers?
Which pairs cause most trouble?
Letters and digits that resemble each other, such as O and 0 or I and 1. A supplier uses the standard shapes so the difference is clear.
Characters such as O and 0, or I and 1, can look alike, and some registrations are chosen because they read as words. The legal font defines their shapes, and altering a letter to look more like a number is not allowed. See the car registration plate font for what the typeface requires.
What Does The Legal Font Require?
Why do font and spacing go together?
Each character is designed with its own width and side gaps, so changing the typeface changes the spacing even if the plate looks tidy.
The characters must be in the standard typeface, a version of Charles Wright 2001, at the correct size and stroke. The font and spacing work together, so a different font changes the spacing even if the gaps appear similar.
- Use the standard typeface only.
- Keep characters at the correct size.
- Maintain the specified stroke width.
- Keep spacing as in the standard.
How Do Short And Older Registrations Get Spaced?
Short and dateless registrations use the same rules, but the layout is different because the characters are fewer. A supplier fits them to the plate in a compliant way. For older formats such as prefix or suffix plates, the gaps between groups follow the format. See dateless number plates.
What about one-line versus two-line plates?
Some plates, such as those on motorcycles, may be shown on two lines. The rules for layout and spacing apply to those too, so check GOV.UK for the vehicle type.
Do 3D And 4D Plates Follow The Spacing Rules?
Does a gel finish change the layout?
No. It adds a surface finish, not a different arrangement.
Yes. Raised or gel plates are legal only if they meet the same standard, including the font, spacing, colours and reflectivity. Extra depth or decoration cannot change the layout. See 3D reg plates.
Do Spacing Rules Apply To Motorbikes?
Yes, with a size suited to the plate. Motorbike plates may be smaller and the characters are scaled, but the layout rules still apply. See motorbike number plates and UK number plate size.
What Are The Rules For Personalised And Private Plates?
A private plate is bought for the characters, but the layout is the same as any other. The DVLA assigns the registration and does not set how it is spaced beyond the standard. A cherished number plate such as a short or dateless registration also follows the standard layout, though fewer characters mean fewer gaps to get wrong.
- The registration comes from the DVLA; the layout comes from the standard.
- A supplier fits the characters to the plate in the compliant arrangement.
- Customers cannot ask for non-standard spacing from a lawful supplier.
- Plates for show are a separate category and must stay off the road.
How Do I Know If My Plate Has The Wrong Spacing?
Compare it with a plate from a registered supplier. A compliant plate shows even spacing, a clear group gap, crisp characters and the supplier's markings. If the plate looks crowded or oddly spread, ask a supplier to look at it.
- Characters touching or overlapping.
- Uneven gaps within a group.
- A group gap that is too small, too large or missing.
- Characters in a stylised font.
- No supplier name and standard number.
What Happens If The Spacing Is Wrong?
Is it only the keeper who can be penalised?
The keeper or driver is normally responsible, and a supplier who makes a non-compliant plate may also face action.
A plate with incorrect spacing can cause an MOT advisory or failure, attract police attention and lead to a fixed penalty or prosecution. The consequences depend on how far the plate departs from the standard. Check GOV.UK for the current position. See what fails an MOT.
Can I fix it myself?
Do not alter the plate with tape, paint or stickers; these are not allowed. Get a compliant replacement from a registered supplier.
How Do I Get A Correctly Spaced Plate?
Use a registered number plate supplier. They must see proof of identity and of entitlement to the registration, and they make the plate to the standard. See number plate machine for how plates are produced and can you make your own number plate for why home-made plates do not work.
What do I need to take?
Photo identity, and a document showing entitlement such as a V5C, V750 or V778 retention document.
What Are The Common Myths About Spacing?
Where does the confusion start?
From novelty plate adverts and car-show photos, where plates are made for display rather than the road.
- Myth: spacing is a style choice. It is a legal requirement.
- Myth: a small tweak does no harm. Even small changes can be non-compliant.
- Myth: a plate that spells a word is fine. Only if it keeps the standard layout.
- Myth: it is only the supplier's problem. The keeper is responsible for the plates on the vehicle.

Frequently Asked Questions
Are number plate spacing changes illegal?
Yes, if they depart from the standard layout or change how the registration reads. Plates must follow BS AU 145e, with the standard gaps within and between groups. Moving the gap, squeezing characters or spreading them to form a word can fail an MOT and lead to a fine.
What is the correct number plate spacing?
The correct spacing is set by BS AU 145e and the display regulations: even gaps between characters in a group and a standard larger gap between groups, with set margins. A registered supplier makes the plate to these measurements. Check GOV.UK for the current detail.
Can I space my plate to spell a word?
No. The characters must not be altered, styled or spaced to look like something else. Choose a registration that reads well and keep the standard layout. A supplier cannot lawfully make a plate that departs from the standard.
Is a missing gap on a current style plate allowed?
No. A current style plate has a standard gap between the age identifier and the three random letters. Removing or resizing it makes the plate non-compliant and can cause an MOT failure.
Do 3D plates have different spacing rules?
No. Raised or gel plates are legal only if they meet the same standard as flat plates, including font, spacing, colours and reflectivity. Decoration must not change the layout or the legibility of the characters.
Can I fix wrong spacing with tape or paint?
No. Tape, stickers, paint or pre-cut characters to alter a plate are not allowed. If the spacing is wrong, replace the plate with one from a registered supplier that meets the standard.
Who checks number plate spacing?
The police, enforcement staff using cameras and MOT testers can all notice a plate that is not compliant. Suppliers are also expected to make plates to the standard. The keeper is responsible for the plates on the vehicle.
Does the spacing rule apply to motorbike plates?
Yes. Motorbike plates may be smaller and the characters are scaled to suit, but the layout and spacing rules still apply. A registered supplier can make a compliant plate for your bike.
