Venum Mens BJJ Gi Size Guide

Venum men's BJJ gis are pre-shrunk and built for nightly rolls, drilling and competition. Sizing follows the IBJJF A-grade system (A0 through A4, with half sizes A1.5 and A2.5 for in-between body types), mapped against height in both feet/inches and cm, plus a corresponding men's clothing size for quick reference. Browse matching rashguards, spats and belts in the Venum collection.

Fit tip: All Venum gis are pre-shrunk, so what arrives is the size you'll be rolling in. Choose the larger size for a roomier gi with longer sleeves and legs; size down for a more fitted cut. Sizes are indicative — account for your body type and weight if you sit between two A-grades.

Size Sleeves Length Leg Length Height (ft) Height (cm) Clothing Size
A0 57.5 in 35 in 4'11 - 5'1 150 - 156 cm XS
A1 60 in 36 in 5'1 - 5'4 157 - 163 cm S
A1.5 62 in 38 in 5'4 - 5'6 164 - 170 cm S/M
A2 65 in 39 in 5'6 - 5'9 171 - 177 cm M
A2.5 68 in 41 in 5'9 - 6'0 178 - 184 cm M/L
A3 70 in 42.5 in 6'1 - 6'3 185 - 191 cm L
A4 72.5 in 42.5 in 6'3+ 192+ cm XL/XXL

Venum publishes sleeve and leg lengths in inches and height in both feet/inches and centimetres — multiply inches by 2.54 to convert to cm if needed.

How to measure

  • Height: Stand against a wall in bare feet and measure from the floor to the top of the head.
  • Sleeve length: From the centre back of the neck, across the shoulder, and down to the wrist with the arm extended.
  • Leg length (inseam): From the top of the inner thigh down to the ankle bone.
  • Bodyweight cross-check: If you're at the heavier end of a height range, go up one size (e.g. A1.5 instead of A1).

Not sure which size to pick? For competition use under IBJJF rules, accurate sleeve length matters — a gi where the cuff sits above the wrist when the arm is extended will get flagged at weigh-in. We offer 30-day returns on unworn gis with tags attached. Browse the full Venum collection for matching rashguards, spats and BJJ belts.
