How a boxing bout works

Shown with amateur (Olympic-style) boxing under World Boxing's rules.

1. Two boxers score with clean punches from the knuckle part of the glove to the front and sides of the head and body, above the belt.
2. A bout is three rounds. Five judges score each round: 10 to the boxer who won it, and 9, 8 or 7 to the other, depending on the margin.
3. A boxer knocked down gets a count that always goes to at least eight. One not fit to go on by ten has lost by knockout.
4. If nobody is stopped, the judges' totals decide: a unanimous decision when all five pick the same winner, a split one when they do not. A bout cannot be drawn.

How long

Three rounds of three minutes for adults, with a minute's rest between them. Under-17s box two-minute rounds.
