Fairtex BJJ Belt Size Guide
Fairtex BJJ belts come in adult sizes A0–A4 and kids sizes M1–M4, with lengths in centimetres. Pick by your Gi size first — it's the simplest rule and works for most people. If you want a more precise fit, measure around your waist twice plus 30–40 cm for the tying allowance.

| A2 | 280 |

| A4 | 328 |
Kids belts

| M4 | 259 |
How to choose your size
- Easiest rule — match your belt size to your Gi size (A1 Gi = A1 belt, A2 Gi = A2 belt, etc.).
- If you're measuring — wrap a tape around your waist over your Gi, double the measurement, and add 30–40 cm for the tying allowance. Match the total to the closest length above.
- Between sizes — most people prefer the longer size for easier tying and a more secure double knot.
Fairtex BJJH1 Hemp BJJ Belt Black
Designed for fighters who train in the Gi every day, the Fairtex BJJH1 Hemp BJJ Belt in Black is a heavyweight competition-grade belt that holds knot tension through long roll sessions. Crafted from a hemp and cotton weave, this belt resists fraying, holds shape over years of use, and breaks in beautifully against the body.
The reinforced four-row stitching keeps the belt rigid where it counts, and the matte black finish wears in to a soft, broken-in feel without losing structure.
Main Features:
- Hemp and cotton construction with strong knot retention
- Reinforced four-row stitching for competition durability
- Standard IBJJF-friendly width and length
- Handmade in Thailand for authentic craftsmanship
- Matte black finish that breaks in over years of training
