It measures 6.1 metres on each side. In each corner is a post which holds ropes which delineate the edges of the ring. There are four ropes, the lowest 40 centimetres above the floor and the highest about 1.3 metres above the floor. The floor of the ring consists of canvas stretched over a soft underlay. The idea is to score points by punching the opponent within the target area, or to punish him badly enough that he cannot continue.
Boxers wear gloves provided by the Olympic organisers.
Points are scored when a boxer strikes his opponent on the side or front of his torso or head with a clenched fist. The punch must carry force and use the knuckle of the glove, which is marked by a broad white stripe. Punches which strike the arms and those which carry no force do not score points. Five judges decide when a point is scored, using an electronic system. For a point to be recorded, at least three of the judges have to approve of the punch.
