Amateur boxing bouts are short in duration, comprising three rounds of three ...
. A boxing match is usually scheduled for a fixed weight class, and each boxer's weight must not exceed the upper limit. Although professional boxers may fight above their weight class, an amateur boxer's weight must not fall below the lower limit. A nonstandard weight limit is called a
catchweight.
Weigh-in
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 catchweight non-title fight.
The
International Boxing Federation (IBF) has a unique weigh-in policy in title fights. In addition to making the weight at the official weigh-in the day before the fight, the boxers are required to submit to a weight check on the morning of the fight. During this later weigh-in, the fighter must weigh no more than above the weight limit for the fight. If a boxer skips the morning weigh-in, or fails to make weight at that time, the fight can still proceed, but the IBF title will not be at stake. In heavyweight title fights, the second weigh-in is still mandatory, but since there is no upper weight limit in that class, a boxer can only be sanctioned for failing to submit to the weigh-in.
An amateur boxer must make the weight at the initial weigh-in; there is no opportunity to try again later. Boxers who fail to make their projected weights are eliminated from their bouts. If the boxer fails a drug test, they are eliminated from the bout as well. 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.
[AIBA, ''Technical & Competition Rules'', §5.1] 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

Culture
A boxer may fight different bouts at different weight classes. The trend for professionals is to move up to a higher class as they age, with muscle mass and bone density increasing over time. Winning titles at multiple weight classes to become a "multiple champion" is considered a major achievement. In amateur boxing, bouts are much shorter and much more frequent, and boxers fight at their "natural" weight.
One boxer is said to be better "
pound for pound" than another if he is considered superior with due regard for their difference in weight. Theoretical comparisons of the merits of boxers in different weight classes are a popular topic for boxing fans, with a similar speculative appeal to comparing sports figures from different eras; in both cases, the competitors could never face each other in reality.
History
In the early nineteenth century, there were no standard weight classes. In 1823, the ''
Dictionary of the Vulgar Tongue'' said the limit for a "light weight" was 12
stone (168 lb, 76.2 kg) while ''Sportsman's Slang'' the same year gave 11 stone (154 lb, 69.9 kg) as the limit.
Size mismatches were dangerous for the smaller boxer and unsatisfying for the spectators. National and world titles could only become recognised if standard weight classes were agreed upon. Important sets of weight classes were those specified in 1909 by the
National Sporting Club of
London

After the split in the 1960s between the WBC and the WBA, the divisions were narrowed, creating more champions simultaneously, and making it easier for fighters to move between different weight divisions. Among the professional bodies, the names of the new divisions are not standardized between different sanctioning bodies, although the cutoff weights are. These weights are specified in

Glamour divisions
Boxing has its own "Original Eight" weight divisions, also known as the "traditional", "classic", or "glamour" divisions. These divisions are the most prominent and widely recognized weight divisions in boxing.
Manny Pacquiao has won world championships in the greatest number of the glamour divisions, winning championships in the flyweight, featherweight, lightweight, and welterweight divisions.
Tweener divisions
The newcomer weight divisions or "tweener divisions", mostly recognized with either a "super", "light" or "junior" in front of their names, took many years to be fully recognized as legitimate weight divisions in boxing. Manny Pacquiao has won world championships in four of these divisions; super bantamweight, super featherweight, light welterweight and light middleweight.
Catchweights
A nonstandard weight limit is called a ''catchweight''. A catchweight may be agreed to for an individual bout—sometimes even for a championship bout—but championships are awarded only at the standard weight classes. For example, when
Manny Pacquiao fought
Antonio Margarito at a catch-weight of 150 pounds, the
World Boxing Council sanctioned this as a title fight for jr. middleweight, whose limit is 154 pounds.

Amateur boxing
When the
(amateur) International Boxing Association (AIBA) was founded in 1946 to govern amateur boxing, it
metricated the weight class limits by

them to the nearest
kilogram. Subsequent alterations as outlined in the
boxing at the Summer Olympics article; these have introduced further discrepancies between amateur and professional class limits and names. The lower weight classes are to be adjusted in September 2010, to establish an absolute minimum weight for adult boxers.
Amateur weight classes also specify the ''minimum'' weight (which the same as the maximum weight of the next highest class).
For safety reasons, fighters cannot fight at a higher weight. This also meant that even the heaviest weight class has a limit, albeit a lower bound. The lower limit for "heavyweight" was established in 1948 at 81 kg. When a new limit of 91+ kg was established in 1984, the name "heavyweight" was kept by the 81+ kg class, and the 91+ kg class was named "super heavyweight", a name not currently used in professional boxing.
Classes are as follows:

The event format is geared so that the finals of all represented weight classes are held over the last two days of the competition, entrants that fail to win on the penultimate day being the Bronze medal recipients with the finals deciding Gold and Silver on the final day, all of the bouts are scheduled in ascending order of weight with the super heavyweight final last of all.
Each weight class conducts preliminary and qualification bouts, for all represented classes where the number of entrants requires multiple match-ups before the finals, with the match-ups of the lightest weight class requiring such fighting first and continuing with each subsequent higher weight class as required, further, second, third and fourth round match-ups may be required to complete the schedule using the same weight class progression to ultimately reach the final
