Bantamweight Weight Limit
The bantamweight limit is 118 lb (53.5 kg). This guide gives the exact figure, the divisions either side and how the weigh-in process can turn into a betting angle. Live prices on any fight sit in the sportsbook.
The exact limit and the divisions around it
Bantamweight is capped at 118 lb, or 53.5 kg. The division directly below is super-flyweight — also called junior-bantamweight — at 115 lb (52.2 kg); the division above is super-bantamweight at 122 lb. A fighter coming up from super-flyweight or down from super-bantamweight carries a different physical profile, and that gap can matter when a fight is priced.
Weigh-in, cuts and the drained-fighter angle
The limit is confirmed at a weigh-in the day before the fight, so fighters cut hard to make 118 lb and then rehydrate overnight. A bout agreed above the limit is a catchweight, which changes the terms. Watch the drained fighter: someone who struggled to make weight or missed it can look hollowed-out on the night, and that feeds method-of-victory and over/under rounds thinking. Weight news is one reason a title fight price can move late.
