Size Guide

Sizing for grappling apparel comes down to two numbers most of the time: the body girth nearest the seam (chest, waist, hip) and the wearer's height. The cut decides the rest. Use the chart that matches the piece, and read the notes — they're the bit suppliers usually skip.

Rashguard sizing

Compression should feel like a firm hand on the shoulder — not crushing, not loose. If you can pinch more than 2 cm of fabric anywhere on the torso, size down. A rashguard that bunches under the gi is a rashguard that grips at the wrong moment.

Men's rashguards

Size	Chest	Waist	Height
XS	86–92 cm	71–76 cm	160–168 cm
S	92–98 cm	76–81 cm	168–175 cm
M	98–105 cm	81–87 cm	173–180 cm
L	105–112 cm	87–94 cm	178–185 cm
XL	112–120 cm	94–102 cm	183–190 cm
XXL	120–128 cm	102–110 cm	185–195 cm

Women's rashguards

Size	Bust	Waist	Height
XS	78–84 cm	60–66 cm	153–160 cm
S	84–90 cm	66–72 cm	160–167 cm
M	90–96 cm	72–78 cm	165–172 cm
L	96–102 cm	78–84 cm	170–178 cm
XL	102–110 cm	84–92 cm	175–183 cm

Women's rashguards run a women-specific cut — narrower across the shoulder, room through the bust, and a torso length pitched to the shorter average stature. Sizing is not "men's minus one" — match the bust girth as the primary anchor, then height.

Shorts sizing

Shorts size off the waist measurement — taken at your natural waist, not where the shorts sit. Hip room is generous through the thigh on every cut so the shorts don't bind in guard or pinch on a sprawl.

Size	Waist	Hip	Height
S	71–76 cm	89–96 cm	165–173 cm
M	76–84 cm	96–104 cm	173–180 cm
L	84–92 cm	104–112 cm	178–186 cm
XL	92–100 cm	112–120 cm	183–193 cm
XXL	100–108 cm	120–128 cm	188–198 cm

If you sit between sizes, size up — the drawcord takes up the slack at the waist, but you can't add room through the hip. Inseam runs around 20–24 cm depending on cut.

Spats sizing

Spats compression-fit ankle to waist. Use the rashguard waist anchor plus your inseam — full-length spats need the right rise on a tall frame or they'll ride low at the ankle. Hip width is built into the cut.

Size	Waist	Hip	Inseam	Height
XS	66–71 cm	84–90 cm	72–76 cm	158–165 cm
S	71–76 cm	90–96 cm	76–80 cm	165–172 cm
M	76–84 cm	96–104 cm	80–84 cm	172–180 cm
L	84–92 cm	104–112 cm	84–88 cm	178–186 cm
XL	92–100 cm	112–120 cm	88–92 cm	185–193 cm

Compression should be uniform — no concentration at the calf, no bagging at the knee. If the knee panel sits 2–3 cm above the kneecap when you stand, you've got the right inseam.

Still on the fence

Tell us your chest or bust, waist, hip, and height — plus what you actually want the piece to do on the mat — and we'll size it. Drop a note via contact with those measurements and we'll write back the same day.

Sizing for gear we don't currently stock

We don't currently stock gis or belts. The charts below remain for reference — sizing standards are largely consistent across the industry, so this content is useful if you've landed here looking for A-cut gi sizing, BJJ belt lengths, or kids-gi dimensions.

Gi sizing — adults (A-cut)

IBJJF-legal A-cut sizing. Measurements are the wearer's height and walk-around weight, not the gi's. If you sit between two sizes, size down for guard players and up for top-pressure passers — A-cut runs long in the sleeve.

Size	Height	Weight	Best fit
A0	155–165 cm	50–60 kg	Light featherweight, junior crossover
A1	165–172 cm	60–70 kg	Featherweight to light
A2	172–180 cm	70–82 kg	Middle to medium-heavy — most common cut
A3	180–188 cm	82–95 kg	Medium-heavy to heavy
A4	188–195 cm	95–108 kg	Heavy to super-heavy
A5	193–200 cm	108–125 kg	Super-heavy and ultra-heavy
A6	200 cm+	125 kg+	Ultra-heavy, special-order

Pre-shrink notes

Most pearl-weave gis ship pre-shrunk. Cold wash on a delicate cycle, hang-dry, no tumble — and an A2 stays an A2. Hot wash plus tumble dry will pull the body in roughly half a size; that's on the laundry, not the gi.

Belts

Belt sizing is by total length, not by waist. Wrap the belt twice and knot — the working ends should hang 12–18 cm past the knot when tied for sparring. Buying a length under your gi size traps the knot too tight at the waist; over your size, the ends flap into the open guard.

Belt size	Length	Pairs with gi
A0	240 cm	A0–A1
A1	260 cm	A1–A2
A2	280 cm	A2 (most common)
A3	300 cm	A3
A4	320 cm	A4–A5

Rank stripe placement

Black tip goes on the right hand of the wearer when worn. Stripes are applied to the black tip in the order earned. Fresh promotion belts ship blank — your professor decides when the stripes go on.

Kids & youth gis

Kids gis run on M-codes (M0–M4) tied to height and age, not weight — most kids' weight is too inconsistent to size by. If you're buying for a fast-growing kid mid-stripe, size up one M and roll the cuffs once for the first six months.

Size	Height	Approx age
M0	105–115 cm	4–5 yr
M1	115–125 cm	5–7 yr
M2	125–135 cm	7–9 yr
M3	135–145 cm	9–11 yr
M4	145–155 cm	11–13 yr
