Are There Weight Classes in Brazilian Jiu-Jitsu? Understanding BJJ Tournaments

Brazilian Jiu-Jitsu (BJJ) is known for its strategic, technical grappling—and as a sport, it continues to grow around the world. Whether you’re just starting out or considering entering your first tournament, one question often comes up: “Are there weight classes in BJJ?”

The short answer is yes—and they’re a fundamental part of the sport. Weight classes ensure that matches are fair, safe, and competitive, especially since BJJ relies heavily on leverage, timing, and control.

Why Weight Classes Matter in BJJ

Unlike striking sports where size can dominate, Brazilian Jiu-Jitsu emphasizes technique over brute force. That said, physical advantages—such as height, weight, and reach—still play a major role when two equally skilled grapplers face off.

Weight classes exist to:

• Level the playing field and promote skill-based competition
• Minimize risk of injury due to large size differences
• Allow athletes to compete within a safe, manageable range for their body type

Even small differences in weight can significantly affect how a grappling match unfolds. The ability to control or escape from an opponent often comes down to force, balance, and timing—making it essential that both athletes are in the same general range.

Weight Classes in Major BJJ Organizations

The most widely recognized tournament body in the world of BJJ is the International Brazilian Jiu-Jitsu Federation (IBJJF). Their tournaments set the standard for weight classes and competition structure.
Here’s an overview of how weight divisions work under the IBJJF rules:

Adult Male & Female Divisions (Gi)

Male Divisions (in Gi):

• Rooster: up to 127 lbs (57.5 kg)
• Light Feather: up to 141.6 lbs (64 kg)
• Feather: up to 154.6 lbs (70 kg)
• Light: up to 168 lbs (76 kg)
• Middle: up to 181.6 lbs (82.3 kg)
• Medium Heavy: up to 195 lbs (88.3 kg)
• Heavy: up to 208 lbs (94.3 kg)
• Super Heavy: up to 222 lbs (100.5 kg)
• Ultra Heavy: over 222 lbs

Female Divisions (in Gi):

• Rooster: up to 107 lbs (48.5 kg)
• Light Feather: up to 118 lbs (53.5 kg)
• Feather: up to 129 lbs (58.5 kg)
• Light: up to 141 lbs (64 kg)
• Middle: up to 152.6 lbs (69 kg)
• Medium Heavy: up to 163.6 lbs (74 kg)
• Heavy: over 163.6 lbs

Note: These weights include the athlete’s gi (uniform).

Juvenile and Masters Divisions

The IBJJF also divides athletes by age group, such as:

• Juvenile (ages 16–17)
• Masters (ages 30 and up)

Weight classes remain similar across age divisions, but athletes compete only against others in their age group, ensuring fair and appropriate matchups.

How to Prepare for Your Weight Class

If you’re planning to compete in a tournament, it’s crucial to know your weight class and prepare for it in advance. Many BJJ competitions require athletes to weigh in shortly before their match—sometimes just minutes before stepping onto the mat. This means extreme weight cuts aren’t practical (or safe).

Here are some key tips for managing your competition weight:

• Know your target weight: Check the exact limits (in kilograms or pounds) for your division and whether the weigh-in includes the gi.
• Monitor your weight weekly: Use a digital scale and weigh yourself in the same conditions as your upcoming tournament.
• Avoid crash diets: Sudden cutting can leave you dehydrated and weak on the day of the event.
• Focus on nutrition: Stick to a clean diet that prioritizes lean proteins, complex carbs, and hydration.
• Train in your gi: This helps you get used to the weight and warmth of your uniform during matches and weigh-ins.

If you’re close to the edge of a weight class, consider competing up rather than risking performance or health.
