Quick answer: IBJJF weight classes are maximum weight limits used to place competitors into divisions. The correct limit depends on age, sex, belt, and whether the event is gi or no-gi. At IBJJF tournaments, the number shown on the event page is the highest permitted weight, and gi divisions include the uniform at weigh-in. No-gi limits differ because athletes weigh in wearing no-gi competition gear. There is no allowance for arriving slightly over: missing weight can lead to disqualification under the event rules. Because division tables and event details can change, use the live tournament page—not an old screenshot—as the final registration source. This guide organizes the common adult and master limits, explains gi versus no-gi differences, and shows how to choose a division without treating a risky last-minute weight cut as the default.
Last updated: June 28, 2026. This guide summarizes common adult and master IBJJF-style BJJ weight classes, gi vs no-gi differences, weigh-in rules, pounds conversions, and safe division selection. It is a planning guide, not a replacement for the official IBJJF rule book or the weight chart on your tournament page.
IBJJF weight classes chart
The table below shows commonly used adult and master IBJJF-style limits. Use it to plan your bracket, then confirm the official event weight chart before you register. IBJJF’s first championship guide explains that event charts list the maximum allowed weight for that division and that weighing over the registered division limit can lead to disqualification.
| Division | Adult/Master male gi | Adult/Master male no-gi | Adult/Master female gi | Adult/Master female no-gi |
|---|---|---|---|---|
| Rooster | 57.5 kg | 55.5 kg | 48.5 kg | 46.5 kg |
| Light feather | 64 kg | 61.5 kg | 53.5 kg | 51.5 kg |
| Feather | 70 kg | 67.5 kg | 58.5 kg | 56.5 kg |
| Light | 76 kg | 73.5 kg | 64 kg | 61.5 kg |
| Middle | 82.3 kg | 79.5 kg | 69 kg | 66.5 kg |
| Medium heavy | 88.3 kg | 85.5 kg | 74 kg | 71.5 kg |
| Heavy | 94.3 kg | 91.5 kg | 79.3 kg | 76.5 kg |
| Super heavy | 100.5 kg | 97.5 kg | No upper limit | No upper limit |
| Ultra heavy | No upper limit | No upper limit | Usually not used | Usually not used |
How IBJJF weight classes work
IBJJF brackets are organized by weight, age, belt, sex, and uniform format. The weight limit is a maximum, not a target. If your registered division lists 76 kg, you need to be at or under 76 kg at the official weigh-in under that event’s rules.
The official event page matters because each tournament publishes its own registration details, relevant dates, age division table, and weight chart. Local tournaments may copy IBJJF-style categories, simplify brackets, combine divisions, or use different limits, so avoid treating any generic chart as the final source.
Gi vs no-gi weight classes
Gi weight limits are higher because athletes commonly weigh in wearing the gi and belt. No-gi limits are lower because the competition uniform is lighter. For example, the adult male light division is commonly listed as 76 kg in the gi and 73.5 kg in no-gi.
If you are close to the limit, weigh yourself in the exact uniform you expect to wear at the event. For gi tournaments, that means the competition gi and belt. For uniform details, see GrapplerHQ’s IBJJF gi rules guide and BJJ gi size chart.
IBJJF no-gi weight classes
IBJJF no-gi weight classes are usually a few kilograms lower than gi divisions because competitors are not weighing in with a gi. The no-gi columns in the chart above are the main planning reference for adult and master competitors, but the event page remains the final source.
No-gi also has its own uniform requirements. If you are competing without the gi, review GrapplerHQ’s IBJJF no-gi rules guide before choosing a division or packing for the event.
How IBJJF weigh-ins work
IBJJF tells first-time competitors to select a division from the event page’s weight chart in its first championship guide. It also states that the listed weights are the highest allowed weights for the division with uniform on, and that athletes who weigh in heavier than the registered limit will be disqualified.
IBJJF also notes that athletes should be ready one hour before their scheduled division start and that they are called to weigh in when the division is starting. That makes aggressive last-minute cuts risky because there may be little time to recover before your first match.
Age divisions and birth year
Weight class is only one part of registration. IBJJF age divisions are selected from the Belt & Age Divisions table on the event page. IBJJF defines age division by birth year rather than the athlete’s exact birthday. For the full age table, see GrapplerHQ’s IBJJF age divisions guide.
Masters athletes may be able to register in younger divisions, such as Master 2 registering in Master 1 or Adult, while kids and juveniles are generally tied to the specific division for their birth year. Always check the event page before assuming your available age divisions.
BJJ weight classes in pounds
Many U.S. competitors think in pounds, while IBJJF-style limits are usually listed in kilograms. The table below gives rounded conversions for planning. Use the official kilogram limit for registration and weigh-in decisions.
| Kg limit | Approximate pounds |
|---|---|
| 46.5 kg | 102.5 lb |
| 48.5 kg | 106.9 lb |
| 55.5 kg | 122.4 lb |
| 57.5 kg | 126.8 lb |
| 61.5 kg | 135.6 lb |
| 64 kg | 141.1 lb |
| 67.5 kg | 148.8 lb |
| 70 kg | 154.3 lb |
| 73.5 kg | 162.0 lb |
| 76 kg | 167.6 lb |
| 79.5 kg | 175.3 lb |
| 82.3 kg | 181.4 lb |
| 85.5 kg | 188.5 lb |
| 88.3 kg | 194.7 lb |
| 91.5 kg | 201.7 lb |
| 94.3 kg | 207.9 lb |
| 97.5 kg | 215.0 lb |
| 100.5 kg | 221.6 lb |
How to choose your BJJ weight class
The best BJJ weight class is usually the one you can make safely while still training well. For first-time competitors, performance, hydration, and clear decision-making are more important than forcing the lightest possible bracket.
- Start with the event page: choose from the current official chart, not a screenshot or old forum post.
- Weigh in with the right uniform: gi and no-gi limits are not interchangeable.
- Leave a buffer: scales, travel, meals, hydration, and gi weight can all move your number.
- Avoid extreme cuts: most BJJ tournaments do not give athletes a long recovery window after weigh-in.
- Ask your coach: your coach can judge whether a division fits your skill, training schedule, and competition goals.
What is absolute or open class?
Absolute, often called open class, is a bracket where athletes from different weight classes can compete against each other. Entry rules vary by event. Some tournaments restrict absolute by belt, age, placement, or registration status.
Open class can be valuable experience, but it can also create large size differences. Beginners and smaller athletes should ask a coach before entering, especially if they are still learning tournament pacing and defensive positioning.
Weight cutting for BJJ
Most BJJ athletes should avoid aggressive weight cuts, especially at white and blue belt. BJJ matches require repeated high-output efforts, grip endurance, and clear tactical choices. A hard cut can hurt all three.
If you are considering a cut, treat it as a coaching and health decision rather than a simple math problem. GrapplerHQ’s water loading and weight cutting for BJJ guide explains the topic, but safety and qualified guidance should control the decision.
Rules, scoring, and competition planning
Your weight class sits inside a bigger competition rule set. Before registering, review the legal techniques, match length, scoring, penalties, uniform requirements, and division rules for your event. GrapplerHQ’s BJJ rules and scoring guide and BJJ points system guide cover the core rules competitors should know.
Bottom line
IBJJF weight classes are useful planning anchors, but the event page is the final authority. Use the chart above to understand the common adult and master gi/no-gi divisions, then verify your age, belt, sex, uniform, and exact weight limit before registering.
FAQ
What are IBJJF weight classes?
IBJJF weight classes are maximum weight limits used to group athletes by size within age, belt, sex, and uniform divisions. The exact division chart for your tournament should come from the official event page.
Are IBJJF gi and no-gi weight classes different?
Yes. Gi limits are commonly higher because athletes weigh in wearing the gi and belt. No-gi limits are lower because the uniform is lighter.
Do you weigh in with the gi in IBJJF?
IBJJF says the event weight chart lists the highest allowed weight with uniform on. For gi events, competitors should expect the gi and belt to matter at weigh-in, then confirm the specific procedure on the event page.
What happens if you miss weight at IBJJF?
IBJJF states that athletes who weigh in heavier than the limit for their registered division will be disqualified. Do not assume you can change divisions at the scale.
Should beginners cut weight for BJJ tournaments?
Most beginners should avoid aggressive cuts. Competing near your normal training weight is usually safer and often leads to better performance.
