If you’re planning to compete in a Brazilian Jiu-Jitsu tournament sanctioned by the International Brazilian Jiu-Jitsu Federation (IBJJF), it’s essential to understand the official gi requirements before stepping onto the mat.
IBJJF has strict rules regarding gi fit, color, material, and condition. Failure to meet these standards can result in disqualification before your first match begins. This guide breaks down exactly what’s expected so you can arrive confident and competition-ready.
1. Approved Gi Colors
IBJJF only allows the following solid colors in competition:
- White
- Royal Blue
- Black
Gi tops and pants must match in color. Mixing blue tops with white pants, or similar combinations, will not pass inspection. Patches and brand logos are allowed but must be placed according to IBJJF’s patch placement rules.

2. Gi Fit and Length Requirements
The GI must be properly fitted to your body. IBJJF inspectors will check the fit before your match, and competitors can be disqualified for failing to meet these standards.
- Sleeve length: No more than 5 cm above the wrist with arms extended
- Pant length: No more than 5 cm above the ankle
- Gi skirt: Must fall below the glutes when tied
- Sleeve width: A fist must pass through when arm is extended
3. Material and Condition
Gis must be made of cotton or cotton-like fabric, durable enough for grip fighting. Pearl weave, gold weave, and similar fabrics are allowed. Ripstop tops are not permitted (ripstop pants are allowed).
Additional rules:
- Gi must be clean and dry
- No tears, holes, or excessive wear
- No odor or discoloration
4. Belt Requirements
Your belt must match your rank and meet these requirements:
- 4 to 5 cm wide
- Long enough to wrap around twice with 20–30 cm ends
- Include a black rank bar (white for black belts)
Avoid belts that are excessively faded or frayed.
5. Patch and Logo Placement
Patches must follow IBJJF’s approved placement rules:
- Upper arms
- Front chest area
- Upper back
- The thigh area of pants
All patches must be securely sewn and not interfere with grips.
6. Backup GI Required
Always bring at least one backup GI. Accidents, stains, or sudden disqualifications at check-in can leave you unprepared. Most competitors bring two fully approved GIs to every event.
Conclusion: Prepare to Compete with Confidence
IBJJF gi rules are strict but clear. By understanding and following these guidelines, you can ensure your gear won’t be the reason you’re sidelined.
