What Is a Boxing Weight Class and How Do You Find Yours?
Boxing is divided into weight classes so that fighters compete against opponents of similar size. A boxer must weigh at or below the division limit at the official weigh-in; a fighter who is even slightly over the limit is not in that division for that bout.
This tool takes your weigh-in weight in kilograms or pounds and finds the division it falls into for professional men's boxing or the Olympic men's and women's programmes, then shows how far you are from the limit and how much you would need to drop to move down a division.

Why Weight Class Matters So Much in Boxing
Size, reach and punching power all scale with body weight, so the weight limit is the main safety and fairness rule in the sport. Fighters often build their entire training camp around making weight, and a few hundred grams over the limit can cost a title shot or a purse.
Many boxers also fight below their natural walking-around weight and rehydrate after the weigh-in. Knowing the exact division boundaries makes it easier to plan a cut, choose between two neighbouring divisions, or spot when an opponent is moving up or down a class.
?Frequently Asked Questions
The commonly used professional men's divisions run from minimumweight (105 lb) through light flyweight (108), flyweight (112), super flyweight (115), bantamweight (118), super bantamweight (122), featherweight (126), super featherweight (130), lightweight (135), super lightweight (140), welterweight (147), super welterweight (154), middleweight (160), super middleweight (168), light heavyweight (175), cruiserweight (200) and heavyweight (over 200 lb).
Depending on the commission and sanctioning body, a fighter who misses weight may be given a short time to lose the remainder, fined part of the purse, stripped of a title eligibility, or have the bout changed to a catchweight if the opponent agrees. The exact consequences are set in the contract and the sanctioning rules.
No. Olympic classes are defined in kilograms and are fewer in number: for men 51, 57, 63.5, 71, 80, 92 and over 92 kg, and for women 50, 54, 57, 60, 66 and 75 kg. They do not line up exactly with the professional divisions, and class lists have changed between Olympic cycles, so always check the current federation list for your competition.
Not yet. It covers professional men's divisions plus the Olympic men's and women's classes. Women's professional boxing uses a similar ladder, but the limits and the sanctioning bodies vary, so check your organisation's official list.
When the weight is over the top limit of a set that has no open top class (for example the Olympic women's 75 kg class), the tool tells you that there is no heavier class in that set. In the professional men's set and the Olympic men's set the heaviest class is open, so heavier boxers fall into it.
No. Many boxers weigh in dehydrated and then regain several kilograms before the fight. This tool uses whatever weight you enter, so use the number you expect to be on the scale at the official weigh-in, and check the event's own weigh-in timing and any rehydration-limit rules.
