Number plates fonts and spacing

Number plate specifications

When the current registration format was introduced in 2001, regulations governing the construction and display of car number plates were revised. These revised regulations apply to the number plates on any and all vehicles registered on or after 1st September 2001. They also apply to all replacement plates made and mounted on vehicles on or after the same date.

Number plates must now use one specific, mandatory typeface: 'Charles Wright 2001'. Hard-to-read variants, such as multiple stroke and italic fonts, are now prohibited. The one decorative variation still permitted is a 3D effect version of the mandatory typeface. The size and spacing of number plate characters is specified in the regulations.

Identifiers, flags and borders

Optionally, number plates may display one of the following national emblems:

  • British Union flag with 'GB' or 'UK'
  • English flag (St George Cross) with 'ENG'
  • Scottish flag (St Andrew Cross) with 'SCO'
  • Welsh flag (Red dragon on green/white field) with 'WALES' or 'CYMRU'
  • Euro flag (circle of stars) with "GB".

If the Euro/GB configuration is displayed, then the bearer vehicle need not display a separate "GB" emblem when driving within the EU.

Acrylic specification

The colours and reflectivity of number plates are also specified in the regulations, and there is a British Standard (BS AU 145e) which describes the physical characteristics of number plates, including: visibility, strength and reflectivity. Front plates must have black characters on a white background, while rear plates must have black characters on a yellow background.

The British Standard also requires that a number plate must be marked with the following information: the British Standard Number, the name, trade mark, or other means of identification of the manufacturer or component supplier, the name and postcode of the supplying outlet. A non-reflective border is optional. There may be no other markings or material contained on the number plate.
