Introduction
Buying a new BJJ gi?
Finding the perfect size is crucial — not just for looks, but for your comfort, performance, and even tournament rules! A gi that’s too tight or too loose can mess up your training and might even get you disqualified in competitions.
This ultimate guide will walk you through exactly how to choose the right BJJ gi size — stress-free!
1. Why Choosing the Correct Size Matters
A well-fitting gi is more important than you might think. Here’s why:
✅ Comfort:
A properly fitted gi allows you to move freely, whether you’re passing guard, escaping submissions, or setting up sweeps.
✅ Competition Rules:
Tournaments like IBJJF have strict uniform requirements. Sleeves, pants, and overall gi fit are all inspected before you compete.
✅ Durability:
A gi that fits right experiences less stress on seams and fabric, meaning it lasts longer.
✅ Respect:
Wearing a clean, properly fitting gi shows respect for your teammates, coaches, and the martial art itself.
2. Understanding BJJ Gi Sizing
BJJ sizing is unique and doesn’t follow regular clothing sizes. Here’s a quick breakdown:
| Size | Height Range | Weight Range |
|---|---|---|
| A0 | 5’0″–5’4″ | 95–125 lbs |
| A1 | 5’4″–5’8″ | 125–155 lbs |
| A2 | 5’8″–6’0″ | 155–190 lbs |
| A3 | 6’0″–6’3″ | 190–225 lbs |
| A4 | 6’2″–6’5″ | 225–250 lbs |
| A5 | 6’4″–6’7″ | 250–275 lbs |
Notes:
- “A” stands for Adult sizes.
- Women’s gis sometimes use “F” sizing (F1, F2, etc.).
- Kids usually have “M” sizing (M0–M4).
Important:
Each brand can have slight variations — always double-check the specific brand’s size chart before purchasing!
3. Special Gi Cuts Explained
BJJ gis come in various cuts to suit different body types:
💥 Regular (Standard Cut):
Balanced sleeves, body, and pants length — great for most body types.
💥 Slim/Fitted Cut:
Tapered waist and arms — perfect for athletes with lean, athletic builds.
💥 Husky Cut:
Wider shoulders and pants — ideal for stockier, heavier builds.
💥 Long Cut (L sizes):
Designed for taller individuals needing extra sleeve and pant length.
Example: A2L (A2 Long).
💥 Short Cut (S sizes):
Designed for shorter and stockier builds.
Example: A2S (A2 Short).
4. How to Measure Yourself Correctly
📏 Grab a measuring tape and note the following:
- Height: Measure without shoes.
- Weight: Make sure it’s up-to-date.
- Arm Span: Measure fingertip to fingertip with arms stretched out.
- Inseam: Measure from the crotch to the ankle.
Use these measurements to match your perfect size using the brand’s sizing chart.
5. What About Gi Shrinkage?
🔥 Cotton gis shrink — even if they’re labeled as pre-shrunk — usually about 1–3% after a few washes.
Pro Tips:
- Wash your gi in cold water to minimize shrinkage.
- Air dry instead of using a high-heat dryer.
👉 Advice:
If you’re between sizes (for example, between A1 and A2), opt for the larger size — you can always shrink it slightly to fit better.
6. Common Mistakes to Avoid
🚫 Buying based only on height (weight matters too!)
🚫 Ignoring the brand-specific sizing chart
🚫 Over-shrinking your gi with hot dryers
🚫 Choosing a gi that’s too baggy or too tight for competition standards
🚫 Not considering the correct cut (Slim, Husky, Long, Short)
Conclusion
Choosing the right BJJ gi size isn’t complicated when you know what to look for. Measure yourself carefully, match your stats to the brand’s sizing chart, and consider the right gi cut for your body type.
A properly fitted gi will make your rolls smoother, your tournaments sharper, and your BJJ journey way more enjoyable.
