A dartboard is a circular target used in the game of darts, typically made of sisal fibers or cork. It is divided into numbered sections, each representing different point values, and features a bullseye at the center. Players throw small, pointed missiles called darts at the board, aiming to score points based on where the darts land. Dartboards come in various types, including bristle boards for professional play and electronic boards that automatically score games. The standard size for a regulation dartboard is 18 inches in diameter, and it is usually hung 5 feet 8 inches from the floor to the center of the bullseye.
