Boxing Weight Classes - The Weigh-in

The Weigh-in

A professional boxer typically weighs more between fights than at the time of a fight. Part of the process of training for a bout is "getting down to fighting weight". The weigh-in takes place the day before the fight. Boxers typically stand on the scales barefoot and without gloves. The weigh-in is often a photo opportunity and boxers or their entourage may trash talk each other. This element is such a valued part of the build-up that heavyweight boxers go through the ritual of being weighed even though there is no limit to be measured against, even where there appears to be genuine animosity between boxers.

A boxer who is over the weight limit may strip naked to make the weight if the excess is minimal; otherwise, in a professional bout, one can try again later, typically after losing weight in the interim through dehydration by vigorous exercise in a steam room. If the excess weight is too great, the effort expended trying to "make weight" will make the boxer unfit for the fight itself. In such cases, the fight may be cancelled, with the over weight boxer sanctioned; or the fight may proceed as a catch weight non-title fight.

An amateur boxer must make the weight at the initial weigh-in; there is no opportunity to try again later. There is a "general weigh-in" before the start of the tournament and a "daily weigh-in" on the morning of each of a fighter's bouts. At the general weigh-in, the fighter must be between the weight class's upper and lower limits; at the daily weigh-in only the upper limit is enforced. A fighter outside the limit at the initial weigh-in may be allowed to fight in a different class if there is space in the tournament. At major events such as boxing at the Olympics, there is a limit of one boxer per country per weight class.
