When it comes to Brazilian Jiu Jitsu (BJJ) competitions, understanding the BJJ weight class system is crucial for both beginners and experienced fighters. The International Brazilian Jiu Jitsu Federation (IBJJF) has established a comprehensive set of weight classes for both gi and no-gi competitions. However, the complexity of the BJJ weight class system and the numerous age divisions often lead to confusion among athletes. In this complete guide, we will explore the IBJJF weight classes, age divisions, and the rules surrounding weigh-ins and competition. Whether you’re a seasoned competitor or a curious enthusiast, this article will serve as your roadmap to mastering the art of classification in BJJ.

IBJJF Male Adults and Masters Weight Classes

Males Adults and Masters Gi Weight Classes

The IBJJF has defined nine weight classes for male adults and masters in the gi division. These weight classes are designed to ensure fair competition based on the fighters’ body weights. It’s important to note that gi and no-gi competitions have separate weight classes. Let’s take a closer look at every BJJ weight class for competing in the gi:

  1. Rooster (under 57.5 kg / under 127 lbs)
  2. Light feather (above 57.5 kg and under 64 kg / 127 – 141.6 lbs)
  3. Feather (above 64 kg and under 70 kg / 141.6 – 154.6 lbs)
  4. Light (above 70 kg and under 76 kg / 154.6 – 168 lbs)
  5. Middle (above 76 kg and under 82.3 kg / 168 – 181.6 lbs)
  6. Medium heavy (above 82.3 kg and under 88.3 kg / 181.6 – 195 lbs)

  9. Ultra heavy (above 100.5 kg / 222 lbs and up)

In addition to these weight classes, there is also an open BJJ weight class that is open to all weight classes. It’s important to keep in mind that there may be small discrepancies between the weight classes when measured in kilograms or pounds. Be aware of whether you will be weighed in kilograms or pounds to avoid any confusion.

Males Adults and Masters No-gi Weight Classes

Just like in the gi division, there are nine weight classes for male adults and masters in the no-gi division. However, the weight limits for the no-gi divisions are slightly lower compared to their gi counterparts. Here are the weight classes for competing in the no-gi division:

  1. Rooster (under 55.6 kg / under 122.6 lbs)
  2. Light feather (above 55.6 kg and under 61.7 kg / 122.6 – 136 lbs)

  4. Light (above 67.5 kg and under 73.5 kg / 149 – 162.6 lbs)
  5. Middle (above 73.5 kg and under 79.6 kg / 162.6 – 175.6 lbs)
  6. Medium heavy (above 79.6 kg and under 85.5 kg / 175.6 – 188.6 lbs)

Similar to the gi division, there is also an open weight class in the no-gi division that is open to all weight classes. It’s worth noting that the weight limits in the no-gi division are approximately 1.8 kg (4 lbs) lighter than their gi equivalents, with the difference increasing as the weight classes go up.

IBJJF Female Adults and Masters Weight Classes

The IBJJF has recently expanded the weight classes for women, offering a total of eight weight classes in the gi division and eight weight classes in the no-gi division. Let’s take a look at the weight classes for female competitors:

IBJJF Age Divisions

The IBJJF has established 22 age divisions, ranging from 4 years old to 61 years and older. These age divisions ensure fair competition among athletes of similar age and development. Let’s take a closer look at the age divisions and match length in both adults/masters and youth categories:

Adults and Masters Age Divisions and Match Length

The age divisions for adults and masters are primarily based on the competitor’s birth year and the current year. The match length may vary depending on the belt level and age division. Here are the age divisions and match lengths for adults and masters:

  • Adults: (Current Year) – (Birth Year) ≥ 18
  • Masters 1: (Current Year) – (Birth Year) ≥ 30
  • Masters 2: (Current Year) – (Birth Year) ≥ 36
  • Masters 3: (Current Year) – (Birth Year) ≥ 41
  • Masters 4: (Current Year) – (Birth Year) ≥ 46
  • Masters 5: (Current Year) – (Birth Year) ≥ 51
  • Masters 6: (Current Year) – (Birth Year) ≥ 56

Match lengths for adult blue belts and masters 1 purple, brown, and black belts are 6 minutes. Adult purple belts have 7-minute matches, adult brown belts have 8-minute matches, and adult black belts have 10-minute matches. It’s important to note that the match lengths may vary depending on the tournament and organization.

Youth Age Divisions and Match Length

The youth divisions are divided into 14 age groups, ensuring that young competitors are pitted against opponents of similar age and size. The age divisions and match lengths for youth competitors are as follows:

  • Mighty Mite I: (Current Year) – (Birth Year) = 4
  • Mighty Mite II: (Current Year) – (Birth Year) = 5
  • Mighty Mite III: (Current Year) – (Birth Year) = 6
  • Pee Wee I: (Current Year) – (Birth Year) = 7
  • Pee Wee II: (Current Year) – (Birth Year) = 8
  • Pee Wee III: (Current Year) – (Birth Year) = 9
  • Junior I: (Current Year) – (Birth Year) = 10
  • Junior II: (Current Year) – (Birth Year) = 11
  • Junior III: (Current Year) – (Birth Year) = 12
  • Teen I: (Current Year) – (Birth Year) = 13
  • Teen II: (Current Year) – (Birth Year) = 14
  • Teen III: (Current Year) – (Birth Year) = 15
  • Juvenile I: (Current Year) – (Birth Year) = 16
  • Juvenile II: (Current Year) – (Birth Year) = 17

The match lengths for youth divisions may vary depending on the age group and tournament regulations. It’s important to check the specific rules and regulations of each competition to ensure accurate information.

Weighing In Before A Tournament

Weighing in before a tournament is a crucial step in the competition process. The IBJJF has specific rules and guidelines for weigh-ins to ensure fair competition. Let’s take a closer look at the weigh-in procedures for both gi and no-gi tournaments:

Weighing in for Gi Tournaments

In gi tournaments, competitors must weigh in wearing their gi. The weight of the gi is included in the total weight. It’s important to consider the weight of your competition gi when selecting your BJJ weight class. If you are close to the weight limit, opting for a lighter gi may be advantageous.

Weighing in for No-Gi Tournaments

In no-gi tournaments, competitors must weigh in wearing the attire they will compete in. Unlike gi tournaments, there is no weight added for the gi. This means that if you typically fight right on the limit of your weight class in the gi division, you may need to compete in a different weight class in the no-gi division.
