Welterweight Weight Limit
Welterweight's limit is 147 lb (66.7 kg). A fighter must be at or under that mark at the weigh-in, held the day before the fight, then rehydrates before the bell. The cut and the recovery both shape performance, which makes the weigh-in a useful read for bettors. This guide sets out the exact rules and the angles that follow.
The limit and the divisions around it
To make welterweight a boxer weighs 147 lb (66.7 kg) or less. Directly below is lightweight at 135 lb (61.2 kg); between the two sits the super-lightweight (light-welterweight) boundary at 140 lb, outside our division set. Above welterweight are super-welterweight at 154 lb and then middleweight. Fighters often move up through these classes as their frames fill out, so a boxer's natural weight, not just the contracted limit, is worth knowing before you bet.
Cuts, rehydration and catchweights
Because the weigh-in is the day before, fighters drain down to 147 lb then rehydrate overnight, sometimes climbing well above the limit by fight time. A bad cut, or a missed weight handled as a catchweight (an agreed figure off the standard limit), can leave a fighter drained and flat. That drained-fighter angle matters: a stale boxer can underperform regardless of the price. Factor it into method and over/under rounds bets, and watch the weigh-in before you stake.
Frequently asked questions
What is the exact welterweight weight limit?
147 lb, which is 66.7 kg. A fighter must weigh at or under that at the official weigh-in the day before the fight.
What is a catchweight?
An agreed weight between two camps that sits off a division's standard limit, used when fighters from different weight classes meet or when one cannot make the normal limit. It can leave a fighter drained, which is worth weighing before you bet.
