The Age Divisions of the IBJJF

In addition to weight classes, the IBJFF has a few age divisions. The IBJJF breaks these down into the Juvenile, Adult, and Masters divisions. 

  • Juvenile I – This for 16 to 17 year old
  • Juvenile II – For 17 and 18 year olds
  • Adults –  18 is the minimum age, with no max age limit
  • Masters – 30+ (6 age ranges)

The Masters division is divided into several categories. It’s important to remember that anyone in the Masters category is not excluded from competing in the Adult division.

  • Master 1 – 30-35 years.
  • Master 2 – 36 to 40 years
  • Master 3 – 41 to 45 years
  • Master 4 – 46 to 50 years
  • Master 5 – 51 to 55 years
  • Master 6 – 6 to 60 years

The IBJJF Weigh In Process

IBJJF weight classes include the gi. This means that when you go to weigh in at the tournament, they will require you to be wearing the gi. Thus, you need to know in advance how much your gi weighs so you can factor this in when you decide which weight class to compete in.

In case you were wondering, a gi typically weighs 4.2 lbs (or 1.6kg). Similarly, for no-gi, you are required to wear your gi when you weigh in.

Weigh-ins for the IBJJF tournaments occur on the same day of the competition. Typically, these weigh-ins occur 20-30 minutes before the match time. You are only given one time to weigh in and you wont be given another chance to make weight should you fail. 

This is in contrast with other combat sports, like boxing or wrestling. Thus, there is less time to add weight back. This should factor into how you cut weight in BJJ, which should typically only be done by high level competitors anyway.
