FACT: Originally there were only eight weight classes / weight divisions in boxing: Heavyweight (No Limit); Light Heavyweight (12 st 11 lbs Limit); Middleweight (11 st 6 lbs Limit); Welterweight (10 st 7 lbs Limit); Lightweight (9 st 9 lbs Limit); Featherweight (9 st Limit); Bantamweight (8 st 6 lbs Limit); Flyweight (8 st Limit).
FACT: Catch Weight contests are becoming more popular in the modern era. This is where a boxer from a lower division agrees to fight a boxer in the division above, but the weight limit of the higher division is lowered. This forces the heavier boxer to weigh-in lighter than normal and thus bridge the gap between the two divisions. Historically, Catch Weight contests did not qualify as title fights. However, in recent times there has been a growing trend among the governing bodies to sanction such bouts as genuine title fights.
