ADCC World Championship men compete at -66, -77, -88, -99 and +99 kg, and women at -55, -65 and +65 kg, with an absolute division on top. The ADCC Opens use nine men’s and eight women’s classes, printed in kg and lb. Every table below is checked against our data, with the matching IBJJF no-gi class next to each limit.
ADCC World Championship and Trials weight classes
ADCC lists these divisions on its 2026 Trials event pages, which qualify athletes for the World Championship. ADCC prints kilograms only.
| ADCC class | In pounds (converted) | IBJJF no-gi class at that weight |
|---|---|---|
| -66 kg | 145.5 lb | Feather (67.5 kg) |
| -77 kg | 169.8 lb | Middle (79.5 kg) |
| -88 kg | 194 lb | Heavy (91.5 kg) |
| -99 kg | 218.3 lb | Ultra Heavy (no maximum) |
| +99 kg | Over 218.3 lb | — |
Women at the World Championship
Three classes for women, listed on the same 2026 Trials pages.
The World Championship also runs an absolute division, as ADCC’s 2026 announcement states. The ADCC pages we could read do not publish weigh-in times or a weight allowance for the World Championship, so this page does not give one.
| ADCC class | In pounds (converted) | IBJJF no-gi class at that weight |
|---|---|---|
| -55 kg | 121.3 lb | Feather (56.5 kg) |
| -65 kg | 143.3 lb | Middle (66.5 kg) |
| +65 kg | Over 143.3 lb | — |

ADCC Open weigh-ins
From the ADCC Official support page and the weight-class chart. They apply to the ADCC Opens, not the World Championship.
Kids and teens have their own weight tables in the same PDF, split by age group (6 and under, 7–8, 9–10, 11–12, 13–14 and 15–17). Read them in the official chart, linked below.
- Weigh-ins are mandatory for every competitor and are held the day before the event
- Limited same-day options: kids and juveniles weigh in at 6:00 AM, and weigh-ins close at 6:15 AM. Adults must weigh in no later than 2 hours before their division starts
- A 0.5 kg (1.1 lb) allowance is permitted for all weigh-ins
- Adults and masters show a valid ID or passport. Kids and teens show a valid ID, passport or birth certificate
- Absolute divisions are adult only, 18 and over
How ADCC classes line up with IBJJF no-gi
IBJJF no-gi classes have limits like 73.5 and 79.5 kg, and IBJJF weighs no-gi athletes in their uniform (see IBJJF weight classes). ADCC uses round kilogram limits. No ADCC limit on this page matches an IBJJF no-gi limit, so making weight for one does not tell you where you land in the other. The comparison column also assumes you weigh exactly the ADCC limit: the 0.5 kg ADCC Opens allowance and the IBJJF uniform can each push you one class up.
The biggest gap is at the top. ADCC -99 kg and ADCC Open -100 kg both put you over IBJJF no-gi Super Heavy (97.5 kg), so at those weights you are an IBJJF Ultra Heavy. For the rule differences, read ADCC rules explained and IBJJF vs ADCC rules.
Key Takeaways
- ADCC Worlds: men -66, -77, -88, -99, +99 kg. Women -55, -65, +65 kg. Plus an absolute division.
- ADCC Opens: nine men’s classes (-55 to +100 kg) and eight women’s (-50 to +80 kg), printed in kg and lb.
- ADCC Opens allow 0.5 kg (1.1 lb) at every weigh-in.
- No ADCC limit matches an IBJJF no-gi limit, so check both charts before you cut weight.
