Professional boxing has seventeen weight divisions, matching fighters by size for safety and fairness. From lightest to heaviest they are: minimumweight (105 lb), light flyweight (108), flyweight (112), super flyweight (115), bantamweight (118), super bantamweight (122), featherweight (126), super featherweight (130), lightweight (135), super lightweight (140), welterweight (147), super welterweight (154),
Fights that go the distance are decided by three ringside judges using the 10-point must system. In each round, the judge awards 10 points to the fighter he believes won it and 9 or fewer to the other; a close round is 10-9, a round with a knockdown is usually 10-8, and a dominant round can be 10-8 or lower.

Because boxing has no single governing body. Four rival organizations, the WBA (1921), WBC (1963), IBF (1983) and WBO (1988), each sanction their own world championships, rankings and title fights, and each charges fees for the privilege.
