BJJ Belt Measurement
BJJ and Luta Livre Belt Size Guide
Choosing the right BJJ belt size allows you to tie your gi properly, keep solid support and train comfortably in both training and competition. This guide complements the BŌA gi size charts to help you select a belt suited to your body type.
Adult Belts
Adult Brazilian Jiu-Jitsu belts are available in several sizes, usually from A0 to A5, to suit waist size, build and preferred knot style.
Kids’ Belts
The shop also offers kids’ BJJ belts, adapted to young practitioners and available in specific progression colors: white, grey, yellow, orange and green depending on rank.
Colors and Ranks
Adults generally progress from white belt to blue, purple, brown and then black. Each color represents experience, technical level and time spent on the mats.
To check your choice, measure a belt flat or compare it with your current BJJ gi. A well-chosen belt should allow a comfortable double wrap and a stable knot, without restricting movement or grips.
