BJJ Gi Size Chart: Find the Perfect BJJ Gi Size Guide For Your Gi
Choosing the best BJJ Gi is more than just a matter of appearance. It is about comfort, mobility and performance on the mat. It does not matter if you are stepping into your first Brazilian Jiu Jitsu class or preparing for a high-level competition. Understanding the BJJ Gi size chart is essential. A properly fitting Gi allows you to train freely, grip effectively and comply with IBJJF (International Brazilian Jiu Jitsu Federation) regulations.
At Tapout BJJ, we aim to help every practitioner i.e. men, women, and kids, find their ideal Gi fit. This guide breaks down everything you need to know about BJJ Gi sizing. It also gives tips for measuring, adjusting and maintaining the perfect fit.
Understanding BJJ Gi Sizing
Unlike everyday clothing sizes, Brazilian Jiu Jitsu Gis follow a specific alphanumeric system. You will usually see sizes such as A1, A2, or M1, which represent both age group and body type.
- A-sizes (A0–A6): For adult men or unisex fits
 - F-sizes (F0–F4): For women
 - M-sizes (M000–M5): For kids and youth practitioners
 
The “A” stands for Adult, “F” for Female, and “M” for Mini/Kids.
Each size corresponds to a height and weight range. Thus, ensuring that every athlete can find the right Gi.
Choosing your correct BJJ Gi size ensures balance between freedom of movement and IBJJF-approved fit. It requires that sleeves and pants are not excessively short or loose.
Men’s BJJ Gi Size Chart
Men’s Gis, often labeled with A0 to A5 (and occasionally A6), are designed to accommodate a variety of builds. The measurements below are general guidelines to help you choose your Gi.
| Size | Height (cm) | Weight (kg) | Chest (cm) | Gi Length (cm) | 
|---|---|---|---|---|
| A0 | 150–160 | 50–60 | 96 | 151 | 
| A1 | 160–170 | 60–70 | 99 | 157 | 
| A2 | 170–180 | 70–80 | 103 | 164 | 
| A3 | 180–190 | 80–90 | 107 | 170 | 
| A4 | 190–200 | 90–100 | 111 | 178 | 
| A5 | 200+ | 100+ | 116 | 187 | 
These figures serve as an average reference. If you are between two sizes, your choice may depend on fit preference. For example, competitors often prefer a tighter Gi. However, some practitioners prefer a looser fit for daily training sessions.
Women’s BJJ Gi Size Chart
Women’s BJJ Gis are tailored differently than men’s to offer a better anatomical fit, especially around the shoulders, waist, and hips. The following chart helps female athletes choose the perfect balance between mobility and durability.
| Size | Height (cm) | Weight (kg) | Chest (cm) | Gi Length (cm) | 
|---|---|---|---|---|
| F0 | 145–155 | 40–50 | 84.5 | 141 | 
| F1 | 155–165 | 50–60 | 87.5 | 146 | 
| F2 | 165–175 | 60–70 | 92 | 152 | 
| F3 | 175–185 | 70–80 | 96.5 | 159 | 
| F4 | 185+ | 80+ | 100.5 | 166 | 
A well-fitting women’s Gi not only enhances comfort but also prevents loose fabric that opponents can grip easily during sparring. Tapout BJJ recommends checking both height and weight ranges closely, as women’s cuts vary slightly by brand and model.
Kids’ BJJ Gi Size Chart
For young Brazilian Jiu Jitsu practitioners, comfort and safety go hand in hand. A properly fitted Gi ensures unrestricted movement. At the same time, maintaining durability through constant rolling and grappling.
| Size | Height (cm) | Weight (kg) | Chest (cm) | Gi Length (cm) | 
|---|---|---|---|---|
| M000 | 95–105 | 15–20 | 61.5 | 107 | 
| M00 | 105–115 | 20–25 | 65.5 | 114 | 
| M0 | 115–125 | 25–30 | 71 | 124 | 
| M1 | 125–135 | 30–35 | 75 | 131 | 
| M2 | 135–145 | 35–40 | 80 | 137 | 
| M3 | 145–155 | 40–45 | 85 | 143 | 
| M4 | 155–165 | 45–50 | 89 | 149 | 
| M5 | 165+ | 50+ | 94 | 157 | 
As kids grow, Tapout BJJ advises sizing slightly larger if your child is between sizes. Especially if the Gi is non-pre-shrunk cotton, which may shrink slightly after washing.
How to Choose the Right BJJ Gi Size
Selecting the correct BJJ Gi is more than just checking a size chart. Consider the following factors before purchasing:
Height and Weight
Always begin with your height and weight as the base measurement. Most reputable BJJ brands, including Tapout BJJ, design their size charts around these two metrics.
If you are tall but lightweight, choose a size that fits your height and adjust with a belt or tailoring if necessary. Conversely, if you are shorter and heavier, opt for a wider cut Gi.
Pre-Shrunk vs. Non-Pre-Shrunk Fabric
A pre-shrunk Gi maintains its original size even after several washes. On the other hand, non-pre-shrunk Gis can shrink up to 3% after the first wash.
If you buy a non-pre-shrunk BJJ Gi, it is best to size up slightly. Always wash in cold water and air-dry to maintain the Gi’s shape.
Fit Preference
Different athletes prefer different fits:
- Competition Fit: Snug, IBJJF-approved fit that reduces excess fabric.
 - Training Fit: Slightly looser. Thus, allowing more airflow and comfort during long sessions.
 
At Tapout BJJ, many practitioners choose a hybrid fit i.e. tailored enough for performance yet relaxed for comfort.
IBJJF Regulations
If you plan to compete, your Gi must comply with IBJJF standards. These include:
- Sleeve length: No more than 5 cm from the wrist when arms are extended.
 - Pant length: Should not exceed 5 cm above the ankle.
 - Lapel thickness and width restrictions.
 
Choosing an IBJJF-approved BJJ Gi ensures that your uniform passes inspection before matches.
BJJ Gi Fit and Adjustment Tips
- Try before you train: Always try on your Gi before washing. Move around, perform hip escapes and simulate grips.
 - Account for shrinkage: If your Gi feels slightly large before washing, it will likely tighten after the first few washes.
 - Tailoring: If your size falls between two categories, a local tailor experienced with martial arts uniforms can make small adjustments for a perfect fit.
 - Belt compatibility: Ensure that your belt size complements your Gi size. An oversized belt can affect the look and comfort of your uniform.
 
Why the Right Gi Size Matters
A perfectly sized BJJ Gi enhances your overall performance by:
- Allowing unrestricted movement for guard passing, takedowns, and submissions.
 - Preventing opponents from easily gripping excess fabric.
 - Maintaining professional appearance and compliance during tournaments.
 - Improving comfort and confidence, especially during long training sessions.
 
Wearing the correct Gi also prolongs its lifespan, as ill-fitting uniforms often suffer from uneven wear or tension on seams.
Maintaining Your BJJ Gi
Once you have found your perfect fit, maintaining your Gi is just as important. Here are a few quick care tips from Tapout BJJ:
- Wash after every session to prevent odor buildup.
 - Air-dry only, avoid high heat, which causes shrinkage.
 - Store it flat or hanging to preserve the fabric’s structure.
 - Avoid bleach or harsh detergents, they damage stitching and weaken fibers.
 
With proper care, your BJJ Gi will remain durable, comfortable and competition-ready for years.
