IBJJF Weight Classes: Complete Guide to All Divisions (2025-2026)
The definitive guide to IBJJF weight classes for Gi, No-Gi, adult, masters, and juvenile divisions. Includes weight limits, cutting tips, and weigh-in rules.
Understanding IBJJF Weight Classes
The International Brazilian Jiu-Jitsu Federation (IBJJF) uses a comprehensive weight class system to ensure fair competition across all levels. Whether you're competing in your first local tournament or preparing for Worlds, understanding these weight divisions is essential for proper preparation.
This complete guide covers all IBJJF weight classes including adult Gi and No-Gi divisions, masters categories, and juvenile weight classes. We'll also share practical tips for making weight and what to expect at official weigh-ins. Before you register, make sure you're familiar with the full set of IBJJF competition rules.
Adult Male Gi Weight Classes
The adult male Gi division is the most common category at IBJJF tournaments. Here are the official weight limits:
| Weight Class | Weight Limit (kg) | Weight Limit (lbs) |
|---|---|---|
| Rooster | 57.5 kg | 126.8 lbs |
| Light Feather | 64.0 kg | 141.1 lbs |
| Feather | 70.0 kg | 154.3 lbs |
| Light | 76.0 kg | 167.6 lbs |
| Middle | 82.3 kg | 181.4 lbs |
| Medium Heavy | 88.3 kg | 194.7 lbs |
| Heavy | 94.3 kg | 207.9 lbs |
| Super Heavy | 100.5 kg | 221.6 lbs |
| Ultra Heavy | No limit | No limit |
| Open Class | No limit | No limit |
Important: These weights include your Gi. Plan for your Gi to add approximately 1.5-2.5 kg (3.3-5.5 lbs) to your body weight. Review the IBJJF Gi uniform requirements to make sure your competition Gi is legal before weigh-in day.
Warning: The most common weigh-in mistake is forgetting that Gi weight counts. A pearl-weave competition Gi typically weighs 1.5-2.0 kg, while a double-weave can weigh 2.0-2.5 kg. Weigh yourself at home in your full competition Gi at least a week before the event to avoid surprises.
Adult Female Gi Weight Classes
Female competitors have their own set of weight divisions:
| Weight Class | Weight Limit (kg) | Weight Limit (lbs) |
|---|---|---|
| Rooster | 48.5 kg | 106.9 lbs |
| Light Feather | 53.5 kg | 118.0 lbs |
| Feather | 58.5 kg | 129.0 lbs |
| Light | 64.0 kg | 141.1 lbs |
| Middle | 69.0 kg | 152.1 lbs |
| Medium Heavy | 74.0 kg | 163.1 lbs |
| Heavy | 79.3 kg | 174.8 lbs |
| Super Heavy | No limit | No limit |
| Open Class | No limit | No limit |
Adult No-Gi Weight Classes
No-Gi weight classes are slightly different since you're not wearing a heavy Gi. The weights are measured in your competition attire (rash guard and shorts).
Male No-Gi Divisions
| Weight Class | Weight Limit (kg) | Weight Limit (lbs) |
|---|---|---|
| Rooster | 55.5 kg | 122.4 lbs |
| Light Feather | 61.5 kg | 135.6 lbs |
| Feather | 67.5 kg | 148.8 lbs |
| Light | 73.5 kg | 162.0 lbs |
| Middle | 79.5 kg | 175.3 lbs |
| Medium Heavy | 85.5 kg | 188.5 lbs |
| Heavy | 91.5 kg | 201.7 lbs |
| Super Heavy | 97.5 kg | 215.0 lbs |
| Ultra Heavy | No limit | No limit |
| Open Class | No limit | No limit |
Female No-Gi Divisions
| Weight Class | Weight Limit (kg) | Weight Limit (lbs) |
|---|---|---|
| Rooster | 46.5 kg | 102.5 lbs |
| Light Feather | 51.5 kg | 113.5 lbs |
| Feather | 56.5 kg | 124.6 lbs |
| Light | 61.5 kg | 135.6 lbs |
| Middle | 66.5 kg | 146.6 lbs |
| Medium Heavy | 71.5 kg | 157.6 lbs |
| Heavy | 76.5 kg | 168.7 lbs |
| Super Heavy | No limit | No limit |
| Open Class | No limit | No limit |
IBJJF Masters Weight Classes
Masters divisions follow the same weight classes as adult divisions but are separated by age. For a comprehensive breakdown of each category, see our IBJJF masters age divisions guide. The masters age divisions are:
| Division | Age Range |
|---|---|
| Master 1 | 30-35 years |
| Master 2 | 36-40 years |
| Master 3 | 41-45 years |
| Master 4 | 46-50 years |
| Master 5 | 51-55 years |
| Master 6 | 56-60 years |
| Master 7 | 60+ years |
Key Difference: Some masters divisions combine weight classes when there aren't enough competitors. For example, Rooster and Light Feather may be combined into a single bracket at smaller events.
Masters Weight Class Notes
- Masters use the same weight limits as adult divisions
- Registration is based on your age on the first day of the tournament
- You can compete in a younger age division but not an older one
- Match times are shorter in masters divisions (typically 5-6 minutes)
Juvenile Weight Classes
Juvenile competitors (under 18) have modified weight classes:
Juvenile 1 (15-17 years) - Same as Adult Weights
Juvenile 1 competitors use adult weight classes but compete only against other juveniles.
Juvenile 2 (Under 15) Weight Classes
Younger competitors have tighter weight divisions to ensure appropriate matchups.
Gi vs No-Gi Weight Difference
The weight difference between Gi and No-Gi is typically 2 kg (4.4 lbs) less for No-Gi. This accounts for the weight of the Gi itself.
Planning Tip: If you compete in both Gi and No-Gi at the same event, register for both at your current weight. Don't try to cut to different classes for each format.
How IBJJF Weigh-Ins Work
Understanding the weigh-in process helps you prepare properly:
When Weigh-Ins Occur
- Weigh-ins happen on your competition day
- You must make weight before your first match
- Typically done in the bullpen area before your bracket starts
- No second chances - if you miss weight, you're disqualified
Pro Tip: Arrive at weigh-ins with a plan. Use the bathroom beforehand, have a light Gi option ready if you are close to the limit, and know exactly what your competition Gi weighs. Some competitors keep a spare, lighter Gi jacket in their bag specifically for borderline weigh-ins.
What to Expect
- Check-in: Present your IBJJF membership card and ID
- Gi Check: Your Gi will be measured for compliance (Gi divisions)
- Weigh-in: Step on the scale in your competition attire
- Clearance: Receive wristband or stamp indicating you've made weight
Weigh-In Attire
For Gi: Full competition Gi (jacket, pants, belt)
For No-Gi: Rash guard and shorts (competition attire)
Weight Cutting Tips for IBJJF Tournaments
While we don't recommend aggressive weight cutting, here are practical tips for making weight:
The Week Before Competition
- Monitor your weight daily
- Reduce sodium intake 3-4 days out
- Stay hydrated until 24 hours before weigh-in
- Avoid heavy meals the night before
Day of Weigh-In
- Wake up early to allow time for final adjustments
- Skip breakfast until after weigh-in (if needed)
- Bring a light and heavy Gi option
- Use the bathroom before stepping on the scale
Healthy Weight Management
- Compete at your natural weight class
- Don't cut more than 3-5% of body weight
- Focus on losing fat during training camp, not water weight at the event
- Consider moving up a weight class if cuts are affecting performance
Key Takeaway
Aggressive weight cutting is rarely worth it in BJJ. Unlike combat sports with day-before weigh-ins, IBJJF weigh-ins happen on competition day -- often just minutes before your match. Cutting too much weight will leave you dehydrated and fatigued, directly hurting your performance on the mat.
Choosing Your Weight Class
Selecting the right weight class is crucial for competitive success:
Factors to Consider
- Natural Walking Weight: Where do you sit without actively dieting?
- Training Weight: Your weight during normal training periods
- Body Composition: Muscle vs. fat ratio matters
- Competition Experience: New competitors should avoid cutting weight -- read our first IBJJF tournament guide for more beginner advice
- Match Duration: Heavier weight cuts affect cardio in longer matches
When to Move Up or Down
Move Down If:
- You have excess body fat to lose
- You consistently weigh below your division limit
- You feel undersized against opponents
Move Up If:
- Weight cuts are affecting your performance
- You're constantly depleted at competition
- You feel stronger and more energetic at higher weight
Open Class Explained
The Open Class (Absolute) division has no weight limit. Any competitor, regardless of size, can enter. Key points:
- Typically held at major championships
- Tests technique against larger/smaller opponents
- Often features exciting David vs. Goliath matchups
- Separate registration and entry fee from weight division
Weight Class Strategy
Same-Day Multiple Divisions
At IBJJF tournaments, you can compete in both your weight class and the Open Class. Strategy considerations:
- Weight division matches typically before Open Class
- Save energy for your primary division
- Open Class is bonus competition opportunity
- Consider your bracket sizes when deciding
Gi and No-Gi Same Event
Some IBJJF events feature both Gi and No-Gi on different days:
- Can register for same relative weight class in both
- No-Gi weight is 2kg lighter than Gi equivalent
- Consider which format you're prioritizing
Common Weight Class Questions
Can I Compete Above My Weight?
Yes, you can always register for a heavier weight class. However, you cannot compete in a lighter division than your actual weight.
What Happens If I Miss Weight?
Missing weight results in disqualification. You forfeit your entry fee and cannot compete in that division. You may still be able to compete in the Open Class if registered.
Do I Weigh In With My Belt?
Yes, for Gi divisions you weigh in with your complete Gi including the belt. The belt typically weighs 200-400 grams.
Can I Change Weight Classes After Registration?
IBJJF typically allows weight class changes up until registration closes. After that, changes may not be permitted. Check the specific event rules.
Did You Know: The Open Class (Absolute) division lets you compete regardless of weight. Many competitors register for both their weight class and Open Class at major championships, giving them extra matches and a chance to test their skills against bigger or smaller opponents.
Tracking Your Competition Weight
Successful competitors track their weight leading up to events. Key metrics to monitor:
- Morning weight (most accurate)
- Post-training weight
- Weekly averages
- Weight with and without Gi
- Hydration levels
This data helps you understand your body's patterns and makes weight management predictable rather than stressful.
Pro Tip: Start tracking your morning weight daily at least 6 weeks before competition. Your body weight can fluctuate 1-2 kg day to day based on hydration, meals, and training. Weekly averages give you a much more accurate picture of your true walking weight than any single weigh-in.
