Dart boards are usually made of sisal fibers and each section is lined with thin metal wire. The numbers indicating the various scoring sections of the board are normally made of wire, especially on tournament-quality boards, but may be printed directly on the board instead.

Height and distance

In the standard game, the dart board is hung so that the bullseye is 5 ft 8 in (1.73 m) from the floor, eye-level for a six foot man. The oche (pronounced ‘ock-ey’), or throwing line behind which the player must stand, is 7 ft 9.25 in (2.37 m) from the face of the board, though a few British pubs set it at 8 ft (2.44 m) or 8 ft 6 in (2.59 m). For casual play, it is not uncommon to find the oche somewhat further or closer than the tournament standard, either due to rounding of the specified distance (to 7.5 or 8 feet), or just due to measurement error (such as measuring from the wall, rather than using a plumb line to measure from the board face).

History

Various designs of dartboard have been used, and regional variations remain in parts of Staffordshire, Lancashire and Yorkshire. In particular, the Yorkshire board differs from the standard board in that it has no treble ring and has a single, inner bull. The dartboard itself may have its origins in the cross section of a tree, although some historical records suggest that the first standard dartboards were the bottoms of wine casks, hence the game’s original name of “butts”. There is speculation that the game originated among soldiers throwing short arrows at the bottom of the cast or at the bottom of trunks of trees. As the wood dried, cracks would develop, creating “sections”. Soon, regional standards emerged and many woodworkers supplemented bar tabs by fabricating dart boards for the local pubs.

The numbering plan known by many today has a 20 on top; however, a great many other configurations have been used throughout the years and in different geographical locations. By most accounts, the numbering layout was devised by Brian Gamlin in 1896 to penalize inaccuracy. Although this applies to most of the board, the left-hand side (near the 14 section) is preferred by beginners, for its concentration of larger numbers. Mathematically, removing the rotational symmetry by placing the “20″ at the top, there are 19!, or 121,645,100,408,832,000 possible dartboards. There are many different layouts that would penalize a player more than the current setup; however, the current setup actually does the job rather efficiently [1].
