BJJ Weight Classes Explained — IBJJF Divisions and Weigh-In Tips
Weight with the gi, how official weigh-ins work, and what to do if you're overweight — everything you need to know about weight classes.
Weight classes are the basic mechanism that keeps BJJ competition fair. But between gi weight and re-weigh rules, there is plenty that can catch you off guard if you don't know it. This article covers the IBJJF weight class structure and practical tips for weigh-ins.

|---|---|
| Rooster | 57.5 kg |
| Light Feather | 64.0 kg |
| Feather | 70.0 kg |
| Light | 76.0 kg |
| Middle | 82.3 kg |
| Medium Heavy | 88.3 kg |

Your Gi Counts Toward Your Weight
At IBJJF gi tournaments you weigh in wearing your gi, so you need to pick your class with enough margin for the weight of your own gi. Choosing a lighter gi makes weight management easier.
What to Do If You Miss Weight
- At IBJJF tournaments you get only one weigh-in: if you are over the limit you are disqualified on the spot, and weight class changes are not accepted on the day of the event.
- Whether re-weighs or class changes are allowed differs from event to event. Always check the event rules in advance, and ask the organizer if anything is unclear.

Rapid weight loss through saunas or dehydration carries physical, physiological and psychological risks and has long been discouraged. Start well before the tournament and bring your weight down slowly, with a plan. Source: Khodaee et al., Rapid Weight Loss in Sports with Weight Classes (2015)
