Choosing the correct BJJ Gi is one of the most important steps for any Brazilian Jiu-Jitsu practitioner. Whether you are a beginner stepping onto the mat for the first time or an experienced athlete preparing for a tournament, the right Gi size directly affects comfort, performance, and confidence. This complete guide on BJJ Gi Size Chart and Sizing Tips for Competition & Training is written in simple, user-friendly language so that anyone can understand and apply it easily.
In this guide, you will learn how BJJ Gi sizing works, how to read size charts, and how to choose the best fit for training and competition.
2. Understanding jiu jitsu gi sizes (Basics)
BJJ Gi sizes use letters instead of small or large. Men use A sizes, women use F sizes, and kids use C sizes. These sizes depend on height and weight, not regular clothing size. Using a BJJ gi size calculator or size chart gives better accuracy.
BJJ Gi sizing is different from everyday clothes because it must support athletic movement and follow competition rules. A Gi that fits well improves mobility and reduces unnecessary fabric that opponents can grip. This is why checking a BJJ Gi Size Chart and Sizing Tips guide is always recommended before buying.
Meaning of A, F, and C Sizes
- A Sizes: Adult men (A0–A5)
- F Sizes: Adult women (F0–F4)
- C Sizes: Kids and youth (C0000–C3)
Height and weight together determine the correct size. Relying only on shirt or pant size often leads to poor fit.
3. Men’s BJJ Gi Size Chart
Men’s BJJ Gi sizes range from A0 to A5 and are based on height and weight. Husky (H) sizes fit heavier builds, while Long (L) sizes suit taller athletes. Choosing the correct size improves mobility, comfort, and grip defense during training and competition.
| Size | Height Range | Weight Range | Jacket Length | Pant Length |
| A0 | 5’0″–5’4″ | 100–130 lbs | Short | Short |
| A1 | 5’4″–5’8″ | 120–155 lbs | Medium | Medium |
| A1H | 5’4″–5’8″ | 155–190 lbs | Medium | Medium |
| A2 | 5’8″–6’0″ | 165–195 lbs | Long | Long |
| A3 | 6’0″–6’3″ | 200–225 lbs | Longer | Longer |
Regular vs Husky vs Long Sizes
- Regular: Balanced height and weight
- Husky (H): Shorter but heavier athletes
- Long (L): Tall and slim builds
Beginner vs Competitor Fit
Beginners should prioritize comfort, while competitors often choose a tighter fit to reduce grips and pass inspections.
Common Men’s Sizing Mistakes
Ignoring weight range, forgetting shrinkage, and choosing oversized Gis are common errors. Always refer to a Bjj gi size chart men before purchasing.
4. Women’s BJJ Gi Size Chart
Women’s BJJ Gis are designed for female body shape, offering better fit at shoulders, chest, and hips. Sizes range from F0 to F4. Choosing a women-specific Gi improves comfort, mobility, and confidence, especially during long training sessions and competitions.
Women’s BJJ Gi Size Table
| Size | Height Range | Weight Range | Chest Fit | Pant Length |
| F0 | 4’10″–5’1″ | 85–115 lbs | Slim | Short |
| F1 | 5’2″–5’5″ | 115–140 lbs | Regular | Medium |
| F2 | 5’6″–5’8″ | 135–165 lbs | Athletic | Long |
| F3 | 5’9″–5’11” | 165–200 lbs | Relaxed | Longer |
Women’s Gis should not be replaced by men’s sizes, as men’s cuts often feel bulky and restrict movement. Using a Bjj gi size chart female ensures proper fit and comfort.
5. Kids’ BJJ Gi Size Chart
Kids’ BJJ Gi sizes range from C0000 to C3 and are based mainly on height and age. Parents should allow room for growth while keeping sleeves and pants within competition limits. Correct sizing keeps children safe and comfortable during training.
| Size | Age Range | Height | Best For |
| C0000 | 2–3 yrs | Under 3’ | Toddlers |
| C00 | 4–5 yrs | 3’–3’5” | Small kids |
| C0 | 6–7 yrs | 3’5”–4’ | Beginners |
| C1 | 8–9 yrs | 4’–4’5” | Growing kids |
| C2 | 10–11 yrs | 4’5”–5’ | Youth |
Parents should balance growth allowance with safety. Oversized Gis can be uncomfortable and unsafe for children.
6. How to Choose the Right BJJ Gi Size
To choose the right BJJ Gi size, measure height and weight accurately, then match them with the brand’s size chart. Decide whether the Gi is for training or competition and consider shrinkage. When between sizes, sizing up is usually safer.
Steps include measuring correctly, checking charts, and using a BJJ gi size calculator if available. This approach ensures long-term comfort and performance.
7. Competition vs Training BJJ Gi Fit
Training Gis are slightly relaxed for comfort, while competition Gis must fit tighter and follow strict rules. Sleeves and pants must reach specific lengths. Many athletes keep separate Gis for training and competition to avoid last-minute issues.
Organizations like the IBJJF check Gi fit before matches, making proper sizing essential. This is a key part of BJJ Gi Size Chart and Sizing Tips for competitors.
8. How to Know If Your BJJ Gi Is Too Small or Too Big
A BJJ Gi is too small if sleeves rise above wrists, pants above ankles, or movement feels tight. A Gi is too big if excess fabric allows easy grips. Proper fit improves mobility, comfort, and competition approval.
9. Shrinkage and Fabric Impact on Gi Size
Most BJJ Gis shrink slightly after washing, especially cotton ones. Cold water washing and air drying reduce shrinkage. Always consider this factor when choosing the size so your Gi fits correctly after multiple washes.
10. Strength vs Weight in BJJ
In BJJ, technique matters more than strength or weight. Lighter athletes rely on speed, while stronger athletes use pressure. A properly sized Gi supports both styles by allowing movement without giving opponents easy grips.
11. Common BJJ Gi Sizing Mistakes
Common mistakes include choosing size by clothing fit, ignoring weight range, and forgetting shrinkage. Oversized Gis reduce performance and may fail competition checks. Always rely on a proper size chart.
12. Final Buying Tips for Beginners
Beginners should focus more on comfort, durability, and correct sizing instead of color or design. A well-fitted BJJ Gi allows better movement, prevents discomfort, and helps you train longer without distraction. Always choose a Gi that feels comfortable during drills and rolling.
It is best to start with a training Gi rather than a competition Gi. Carefully read the size chart, consider shrinkage, and check user reviews before buying. The right Gi fit builds confidence and helps beginners learn techniques faster and more effectively.
14. Conclusion
Choosing the correct BJJ Gi size improves comfort, performance, and confidence. By using men’s, women’s, and kids’ size charts and following proper fit tips, athletes can avoid mistakes. A well-fitted Gi lets you focus on technique and enjoy Brazilian Jiu-Jitsu.
