Boxing weight classes
The standard name for the divisions in professional boxing. Each class has an upper limit, so the WBO lightweight ceiling is 135 lb or 61.24 kg at the weigh-in.

Professional boxing chart
All professional boxing weight classes in kg, lb and stone
These are the WBO's published professional ceilings in both pounds and kilograms. Because each unit is published to its own precision, the two figures do not always convert perfectly into one another. The calculator applies the ceiling for the unit you enter. Names can vary slightly by organisation, especially where one body says "junior" and another says "super".

Same system, different wording
Weight classes, categories, classifications and groups usually mean the same thing.
Search results use all of these phrases. The useful part is not the wording; it is the limit, the rule set, and whether the event is professional, amateur, white collar or Olympic-style.
Boxing weight categories
The phrase most often used in amateur, Olympic-style and event paperwork. UK amateur boxing is usually organised around kilogram categories rather than the old pound-based pro labels.
Weight classifications in boxing
A more formal way to describe the same system. Governing bodies use these classifications when they sanction contests, rankings and world titles.
Boxing weight groups
A loose search phrase, but the practical answer is still the same: find the upper limit, then check the actual rule set for the contest you are entering.
Minimumweight 105 lb limit
Minimumweight is the lightest common men's professional division. The limit is 105 lb (47.63 kg), and some bodies also call it strawweight.
Cruiserweight 200 pounds
Cruiserweight tops out at 200 lb (90.72 kg). Above that line, standard professional boxing moves into heavyweight with no upper limit.
How the system works
A weight class is a ceiling, not a body type.
The cleanest way to understand boxing divisions is to ignore the name for a second and look at the limit. The number is what decides the contest.
Weight limit
The maximum a boxer can weigh at the official weigh-in for that division. A welterweight contest has a 147 lb (66.68 kg) limit, not a target weight.
Making weight
Weighing at or below the agreed limit. Missing weight can cost money, titles, rankings, or the fight itself.
Catchweight
A negotiated weight that sits outside a standard title limit, such as 65.8 kg (145 lb) or 68.0 kg (150 lb).
Rehydration
The weight a boxer regains after the weigh-in. This is why fight-night size can look very different from the official weigh-in number.
Moving up
When a boxer leaves a lower division for a heavier one, usually because making the old limit is too hard or because a bigger opportunity is available.
Junior, super and light
These words often describe the same bridge divisions. For example, super welterweight, junior middleweight and light middleweight all point to 154 lb (69.85 kg) in common professional use.
Division by division
What each boxing weight class feels like
The numbers tell you the limit. The notes below tell you what to watch when you are studying fighters in each division.
47.63 kg limit
Minimumweight
105 lb · 7 st 7 lb
The smallest common men's professional division. It is strongest historically in Mexico, Japan, Thailand and other smaller-weight boxing cultures.
Watch for
Speed, balance and volume matter more than one-shot power.
48.99 kg limit
Light flyweight
108 lb · 7 st 10 lb
Only three pounds above minimumweight, so small differences in making weight can change the division.
Watch for
Fast exchanges, clean pivots and punch selection under pressure.
50.80 kg limit
Flyweight
112 lb · 8 st 0 lb
One of the original eight traditional boxing divisions and still one of the best divisions for pure speed and craft.
Watch for
Foot speed, punch accuracy and how quickly fighters reset after combinations.
52.16 kg limit
Super flyweight
115 lb · 8 st 3 lb
A tiny jump on the scale, but often a serious jump in strength and punch resistance.
Watch for
Body punching, pressure and high-level inside exchanges.
53.52 kg limit
Bantamweight
118 lb · 8 st 6 lb
Another traditional division. Bantamweight often sits in the sweet spot between speed, spite and clean punching.
Watch for
How elite fighters create power without needing much mass.
55.34 kg limit
Super bantamweight
122 lb · 8 st 10 lb
Four pounds above bantamweight. It is often where smaller elite fighters carry power up without losing too much speed.
Watch for
Counter punching, angles and whether power still carries after moving up.
57.15 kg limit
Featherweight
126 lb · 9 st 0 lb
A traditional glamour division with a long history of brilliant movers and punchers.
Watch for
Ringcraft, rhythm changes and how fighters manage distance without giving up ground.
58.97 kg limit
Super featherweight
130 lb · 9 st 4 lb
A bridge between featherweight speed and lightweight strength.
Watch for
Whether a fighter can still move like a featherweight while punching like a lightweight.
61.24 kg limit
Lightweight
135 lb · 9 st 9 lb
One of boxing's great traditional divisions. Many all-time greats either built their reputation here or passed through it.
Watch for
Complete boxing: jab, feet, defence, body punching and ring control all show up clearly around 61.24 kg (135 lb).
63.50 kg limit
Super lightweight
140 lb · 10 st 0 lb
A small step above lightweight. It often suits fighters who are too big for 61.24 kg (135 lb) but not yet natural welterweights.
Watch for
Pace, strength in the clinch and whether the boxer can hold centre ring.
66.68 kg limit
Welterweight
147 lb · 10 st 7 lb
Historically one of boxing's deepest divisions. It combines elite speed with enough size for major punching power.
Watch for
How fighters manage distance, feints and counters against opponents who can hurt them with one clean shot.
69.85 kg limit
Super welterweight
154 lb · 11 st 0 lb
The bridge between welterweight and middleweight. Fighters here are often tall, sharp and physically strong.
Watch for
Range control and whether a boxer can punch hard without loading up.
72.57 kg limit
Middleweight
160 lb · 11 st 6 lb
A traditional division with a strong claim to being boxing's classic balance point: big enough to hit hard, small enough to stay fast.
Watch for
Jab authority, body work and how fighters handle pressure in the pocket.
76.20 kg limit
Super middleweight
168 lb · 12 st 0 lb
A modern division that has produced some of the best British boxing nights of the last 30 years.
Watch for
Physical strength, punch variety and how fighters handle long-range pressure.
79.38 kg limit
Light heavyweight
175 lb · 12 st 7 lb
The last division before the old cruiserweight jump. Mistakes are punished quickly at this size.
Watch for
Composure under fire, guard discipline and whether a fighter can keep shape after being hit.
90.72 kg limit
Cruiserweight
200 lb · 14 st 4 lb
Created to stop natural 81.6 to 88.5 kg (180 to 195 lb) fighters being forced straight into the heavyweight giants.
Watch for
Heavyweight-style power with more movement than many bigger fighters can manage.
Over 90.72 kg limit
Heavyweight
Over 200 lb · Over 14 st 4 lb
The only standard professional division with no upper limit. That is why heavyweight size differences can be huge.
Watch for
How the smaller heavyweight handles range, clinches, ring position and the physical cost of every exchange.
Amateur and Olympic boxing
Amateur boxing uses kg categories, and they do not map neatly to pro names.
The table shows England Boxing's 2026 Senior Development championship categories. They are not the same as the international professional divisions, and junior, youth, elite and particular event categories can differ. Olympic boxing uses a smaller event programme again.
For H&G members
If you are thinking about competing, do not choose a category from a website. Train consistently, let your coach see your natural training weight, and agree the safest category for the actual event rules.
| 2026 Senior Development | Men's category | Women's category |
|---|---|---|
| Category 1 | 47 to 50 kg | 45 to 48 kg |
| Category 2 | Under 52.5 kg | Under 51 kg |
| Category 3 | Under 55 kg | Under 54 kg |
| Category 4 | Under 57.5 kg | Under 57 kg |
| Category 5 | Under 60 kg | Under 60 kg |
| Category 6 | Under 62.5 kg | Under 62.5 kg |
| Category 7 | Under 65 kg | Under 65 kg |
| Category 8 | Under 70 kg | Under 67.5 kg |
| Category 9 | Under 75 kg | Under 70 kg |
| Category 10 | Under 80 kg | Under 75 kg |
| Category 11 | Under 85 kg | Under 80 kg |
| Category 12 | Under 90 kg | Over 80 kg |
| Category 13 | Over 90 kg | Not listed |
Paris 2024 men
51 kg, 57 kg, 63.5 kg, 71 kg, 80 kg, 92 kg, +92 kg
Paris 2024 women
50 kg, 54 kg, 57 kg, 60 kg, 66 kg, 75 kg
What is my boxing weight class?
Find your boxing weight class.
Enter your normal weight in kg or lb. The calculator finds your current class under the rules you choose, then lets you inspect one class down and one class up.
Height does not determine a boxing weight class. It can affect reach and how you box within the division, so you can add it for context, but the scale decides the result.
Boxing weight class calculator
Start with the rules, then the number.
Required fields are marked with an asterisk.
Use the result properly
The class below is information, not an instruction.
The up and down buttons explain the scale difference between adjacent classes. They do not tell you to gain or lose that weight. Matchmaking, age, experience, weigh-in timing and the event rules still matter.
Fitness or learning to box
Use the result to follow the sport and find relevant fighters. You do not need to make a division to train recreationally.
The class below is a comparison, not a target. Training consistently matters more than the name beside a number.
White collar or charity bout
Use normal training weight as the starting point, then judge the proposed opponent, weigh-in timing and organiser rules together.
A fair bout near natural weight is better than a lower-sounding class with a last-minute cut.
Amateur competition
The kg category is an event-admin decision, not a vanity target. Age band, rule set, experience and sparring performance all matter.
Choose the actual England Boxing or event rules, then let your coach handle the category decision.
Juniors and parents
Juniors should not change weight from an online chart or an adult professional division list.
The right category is agreed by coach, parent and event rules, with growth and safety ahead of the label.
Common UK reference weights
Quick answers for the weights people actually search.

Safety note
Do not confuse weight classes with weight-cutting advice.
This page explains the divisions. It is not a plan for cutting weight. Cutting water, skipping meals or trying to make a number without a coach is a bad idea, especially for beginners and juniors.
If you are training for fitness, your best weight class is irrelevant. If you are training to compete, the right category is the one your coach agrees is safe, realistic and suitable for the event rules. For the risk side, read the club guide to cutting weight for boxing safely.
FAQ
Boxing weight class questions
What is my boxing weight class?
Enter your normal weight in the calculator on this page, choose kg or lb, then select the rules that apply. The default uses the 17 WBO professional limits. England Boxing Senior Development categories are different, so the calculator also includes the official 2026 men's and women's sets. Height does not decide your weight class.
How many weight classes are there in professional boxing?
Men's professional boxing usually uses 17 standard divisions, from minimumweight at 105 lb (47.63 kg) to heavyweight above 200 lb (90.72 kg). Women's professional boxing often mirrors those limits, but some organisations also use atomweight or slightly different upper limits.
Are boxing weight classes in pounds or kilograms?
Professional boxing usually talks in pounds. The WBO publishes both pound and kilogram ceilings, including 135 lb or 61.24 kg at lightweight. UK amateur and Olympic-style boxing uses different kilogram categories, so always choose the rules for the event.
What weight class is 70 kg in boxing?
In the WBO professional limits, 70 kg is just over 154 lb, so it falls into middleweight rather than super welterweight. In the 2026 England Boxing Senior Development tables, 70 kg is the upper edge of the under-70 kg category for both men and women.
What weight class is 75 kg in boxing?
In the WBO professional limits, 75 kg is about 165 lb and falls into super middleweight, whose ceiling is 168 lb (76.20 kg). In the 2026 England Boxing Senior Development tables, 75 kg is the upper edge of the under-75 kg category for both men and women.
Can a boxer weigh less than the limit?
Yes. The limit is a maximum, not a target. A boxer can weigh below the division limit, although being much lighter than the opponent can create a physical disadvantage.
Should beginners cut weight for boxing?
No. Beginners should not cut water weight or crash diet for training. If you are competing, agree your category with a qualified coach and make weight gradually and safely.
Can I calculate my ideal fight weight?
You can estimate your current boxing reference range, but nobody should treat an online calculator as an ideal fight-weight prescription. The safe starting point is your normal training weight, then a coach can discuss event rules, age, experience and whether competition is appropriate.
What is the lightest boxing weight category?
In the standard men's professional list, minimumweight is the lightest common division at 105 lb (47.63 kg). Some women's professional boxing lists include atomweight below that, depending on the organisation.
Is cruiserweight 200 pounds?
Yes. In standard professional boxing, cruiserweight has a 200 lb limit, which is 90.72 kg. Heavyweight starts above that limit and has no standard upper cap.
Do all boxing governing bodies use the same weight classes?
The major professional divisions are broadly shared, but names, title rules and extra women's divisions can vary by governing body. Amateur, white collar and Olympic-style boxing use different event categories, so always check the actual rules for the contest.
Keep learning
Study the fighters, then train the basics.
Knowing the divisions helps you follow the sport. Getting better at boxing still comes down to stance, guard, footwork, distance, timing and calm repetition.

Come in for a free trial. You do not need to know your division, your style, or your ideal fighting weight. You just need to start with good coaching.
Sources and update notes
The calculator's professional option uses the 17 WBO championship limits. Its amateur options use the England Boxing 2026 Senior Development championship tables in Annex D. Age groups, elite championships and individual events can use different categories, so competitors should always check the current entry rules with a coach. Olympic event categories below are retained as the Paris 2024 programme for comparison.
