Lightweight Weight Limit
The lightweight limit is 135 lb (61.2 kg), and making it cleanly is part of the contest. This guide covers the exact ceiling, the divisions either side, the day-before weigh-in, and how cuts, rehydration and catchweights can affect a fight. For how those factors feed the markets, see the lightweight odds guide.
The exact limit and the divisions around it
A lightweight must weigh no more than 135 lb (61.2 kg) at the official weigh-in. Directly below is super-featherweight, also called junior-lightweight, at 130 lb, and above sits super-lightweight at 140 lb. A bout agreed at a figure between two divisions is a catchweight, where both camps accept a non-standard ceiling for that fight only.
Weigh-in, cuts and rehydration
The weigh-in is usually held the day before the fight, so a boxer who drains hard to make 135 lb has roughly a day to rehydrate. A fighter who struggled badly on the scale can look flat or weight-drained on the night, which is worth weighing before backing them. That fitness and conditioning read feeds into method of victory and over/under rounds markets.
Frequently asked questions
What is the lightweight weight limit?
The lightweight limit is 135 lb, which is 61.2 kg. A fighter must be at or under that figure at the official weigh-in, usually held the day before the fight.
What is a catchweight at lightweight?
A catchweight is a contracted weight that sits outside the standard divisions, for example between super-featherweight at 130 lb and lightweight at 135 lb. Both camps agree to it for that single fight rather than it being an official division.
