Official Dart Board Specs

Ranging from a casual game for children to a sport with international competitions, darts requires little time to learn but a good deal of time to master. Among the skills needed for darts are concentration and an understanding of how projectiles move. The bottoms of wine barrels once served as dartboards in pubs, but official dartboards today must conform to precise specifications, such as those established by the World Darts Federation (WDF). All tournaments organized under the auspices of the WDF must conform to the specifications published in their playing and tournament rules.


African sisal fibers bunched and bundled make a durable and self-healing dartboard. The bristle board fibers close up after you remove the darts, leaving no holes behind. You need steel-tipped darts for use with a bristle board.


A standard dartboard is 17.75 inches in diameter. The circle on the dartboard is equally divided into 20 pie-shaped segments. It contains an inner ring, or bull’s-eye, that is a half-inch in diameter, and an outer ring surrounding the bull’s-eye with a 1.25-inch diameter. Narrow triple ring and double ring bands vary in width from about .32 to .38 inches, depending on the material they are made from. The outside edge of the triple ring is 4.2 inches from the center of the bull’s-eye and the outside edge of the double ring is 6.7 inches away.


Segments on the dartboard are alternately dark and light colored, and each segment possesses a different value, indicating the points earned for a dart that lands on it. Segment value numbers are imprinted on the dartboard in the no-score area. They are always ordered as follows, starting at the 12 o’clock position: 20, 1, 18, 4, 13, 6, 10, 15, 2, 17, 3, 19, 7, 16, 8, 11, 14, 9, 12, 5. The segment valued at 20 is a dark color.


Hang the dartboard so that the 20 is at the top center of the board and the center of the bull’s-eye is 5 feet 8 inches from the floor. Measure 7 feet 9.25 inches out from the wall where the dartboard is hanging and mark a line on the floor behind which players may throw the darts.
