Dart board 

Dart boards are usually made of sisal fibres or boar bristles and are marked 1−20 in a clockwise pattern. A regulation board is 451mm in diameter and is divided into 22 sections. Each section is lined with thin metal wire. The numbers indicating the various scoring sections of the board are normally made of wire. The inner ring is called the ‘bull’.

The overall dimensions are as follows:

  • double and treble ring inside measurement ─ 8mm
  • bull inside diameter ─ 12.7mm
  • outer bull inside diameter ─ 31mm
  • centre bull to inside edge of treble wire ─ 105mm
  • centre bull to outside edge double wire ─ 168mm

Playing area

The dart board is fixed on a wall or mobile stand, allowing for a minimum of 3m between boards measured bull to bull. The dart board is hung so that the perpendicular height from the centre of the bull to the floor is 1.73m, eye-level for a six foot man. The dartboard is fixed such that the ‘20’ segment is coloured black and at the top of the dartboard.

The ochre

The ochre is the line behind which the throwing player stands. It is 25mm high and 915mm long and placed in a position where the minimum throwing distance measured from the rear of the raised ochre is 2.37m along the floor to a plumb line at the face of the dartboard. The diagonal distance from the bull centre to the rear of the raised ochre at floor level is 2.93m.
The encroachment line is a tape line located 1.5m behind the ochre. This is where a player must stand as his/her opponent is playing a shot.

Lighting

All floor dart boards are lit by a suitably positioned light fitting to provide at least 100 watts of light intensity. Alternatively, 20 watts of fluorescent lighting mounted directly above and in front of the dart board at a distance not exceeding 1m from the bullseye is adequate. All lights must be fitted with screens that divert all light away from the player’s eyes when standing at the ochre
