Kid's No Gi Weight Classes, No More

Unfortunately, the IBJJF no longer sanctions No Gi competitions for athletes younger than 16. Therefor, there are no available weight classes for No Gi Kid’s competitions.

Weigh In Rules

In no gi matches, athletes must weigh in before their match. This ensures that athletes are competing within the correct weight category. The weigh in should be conducted before the match, usually at least 30 minutes before, and the athlete must be wearing a legally permissible no-gi uniform.

Attire Clarification

It is important to note that during no-gi matches, athletes must wear a rashguard, spats, and / or shorts. No other uniforms or clothing are allowed and can be grounds for disqualification. You can find more information on no gi uniform requirements here via the IBJJF official website.


In conclusion, no gi weight classes are an important part of the IBJJF’s rules and regulations. Weigh-ins must be conducted at least 30 minutes before a match and athletes must wear a rashguard, spats, and either a gi or shorts. If you wish to compete in an IBJJF tournament, making weight is an important part of the competition. Drastic weight cutting is not a requirement, but if you are on the edge (1-5 lbs), a quick cut before the tournament can make a big difference in your opponents. Come prepared, follow the rules and have a great tournament.
