Many regular people and even BJJ fighters are confused by IBJJF weight classes. There are differences between gi and no-gi competitions. While masters and adults use the same weight classes, juvenile divisions use the same number of weight classes but different weight limits.

But have no fear, we’ve laid out all of the weigh classes below!

Weight classes approved by IBJJF Federation until 2021

The IBJJF weight classes you’ll see below are approved by IBJJF Federation for 2019-2021 and might be subject to change after 2021.

Weighing In Before A Tournament

IBJJF weigh-ins typically happen shortly before your first match. While some competitions give enough time before weigh-in and competition for participants to rehydrate, IBJJF’s time limits mean that it is unlikely you will be able to recover from a weight cut based on water weight.

If you miss weight at weigh-in, you cannot participate in the tournament. There is only one opportunity with no second chances given, so do not fail! Division changes are prohibited, so if you miss weight you will not be competing that day! There are no refunds given if you miss weight.

Weighing in for Gi Tournaments

The gi competition requires you to weigh in wearing your gi, and your total weight counts. You are not
allowed to take the gi off. Be sure to consider the weight of what you will be competing in. If you are right on the edge of your weight class it may not be the best time to wear your double-weave judo gi.

Weighing in for No-Gi Tournaments

If you take part in a no-gi tournament, you will not wear your gi at the weigh-in.

IBJJF Weight Classes–Summary

If you’re planning on competing its vital that you know your target weight class!

The weight classes are the same for adults and master classes, but despite there being the same number of classes for adults and children, the classes are not identical

The IBJJF’s strict weight class policies mean that you may want to err on the heavier side rather than risk missing weight and not being able to compete!
