Choosing the right Brazilian Jiu-Jitsu (BJJ) gi size is just as important as selecting the right fabric or brand. A poorly fitting gi can restrict your movement, make training uncomfortable, and even disqualify you from competitions. That’s why we’ve created this ultimate BJJ gi size guide—to help you find the perfect fit based on your height, weight, and build.
Whether you’re a beginner shopping for your first gi or an experienced grappler exploring a new brand, this guide will walk you through everything you need to know.
🧵 Why Gi Size Matters in BJJ
- Mobility: A too-tight gi limits your range of motion.
- Safety: Excess fabric can be used against you during grips and submissions.
- Compliance: In competitions, your gi must meet strict length and fit requirements.
- Comfort: The right fit prevents irritation, bunching, and overheating.
- Performance: A properly sized gi enhances your movement and confidence.

💡 Tips for Buying the Right BJJ Gi Size
- Check Brand Charts: Always refer to the brand’s size chart—sizes vary widely between brands.
- Consider Shrinkage: Some cotton gis shrink, even when pre-shrunk.
- Look for Adjustable Waistbands: This allows for a better custom fit.
- Buy from BJJ-Specific Brands: They understand fit and function better than generic martial arts manufacturers.
- Try Two Sizes If Unsure: Some online retailers allow free returns on unworn gis.
🧼 Post-Wash Fit: Expect Some Shrinkage
Even “pre-shrunk” gis will shrink a little—up to 5%. Here’s what to expect:
- Hot Wash & Dryer = Maximum shrinkage
- Cold Wash & Hang Dry = Minimal shrinkage
To reduce the risk of an ill-fitting gi:
- Order one size up if you plan to use a dryer
- Always wash cold and hang dry if you want to preserve sizing
