Super Middleweight Weight Limit
The super middleweight limit is exactly 168 lb / 76.2 kg. This guide covers how the weigh-in works, what cutting and rehydration do to a fighter, how catchweights fit in and why a drained body is something to watch before you bet. For live cards, see the sportsbook.
The limit and the weigh-in
To make super middleweight a fighter must weigh at or under 168 lb / 76.2 kg at the official weigh-in, normally held the day before the fight. The division directly below is middleweight at 160 lb / 72.6 kg, and the division above is light-heavyweight at 175 lb. Because the weigh-in is a day early, fighters have roughly 24 hours to rehydrate before the first bell, which is where many of the betting wrinkles come from.
Cuts, rehydration and catchweights
Fighters who cut hard to reach 168 lb then rehydrate can enter the ring well above the limit, which favours the bigger man on the night. A fighter who drains badly to make weight may look hollow and tire early, a genuine angle for the over on rounds or for the opponent. Catchweights, where both sides agree a figure between divisions, change the picture again and are worth checking before you price a fight. Drained-fighter spots often show up best in over/under rounds markets.
Frequently asked questions
What is the exact super middleweight limit?
168 lb, which is 76.2 kg. A fighter must be at or under that weight at the official weigh-in.
Why does a drained fighter matter for betting?
A fighter who cuts too much weight can enter the ring weakened and tire early. That can favour the opponent or push a fight longer, which is worth weighing on the rounds markets.
