Height and distance

In the standard game, the dartboard is hung so that the bullseye is 5 ft 8 in (1.73m) from the floor: eye-level for a six foot person. The oche (IPA: /'?ki/) - the line behind which the throwing player must stand - is generally 7 ft 9¼ in (2.37m) from the face of the dartboard measured horizontally. This is the recognised world standard as set by the World Darts Federation and is played as such in most areas. Due to measurement error this may be incorrect in some places (such as measuring from the wall, rather than using a plumb line to measure from the board face). London 5 board or narrow 5's board set up is slightly different from the standard board. The height is set at 5 feet 6 inches to the center of the bull and the oche is at 9 feet from the face of the board.
