<P> A regulation board is ​ 17 ⁄ inches ( 451 mm ) in diameter and is divided into 20 radial sections . Each section is separated with metal wire or a thin band of sheet metal . The best dartboards have the thinnest wire , so that the darts have less chance of hitting a wire and bouncing out . The numbers indicating the various scoring sections of the board are also normally made of wire , especially on tournament - quality boards . The wire ring on which the numbers are welded can be turned to facilitate even wear of the board . Boards of lesser quality often have the numbers printed directly on the board . </P>
