Guide: BJJ Gi Size Chart
How to use our BJJ gi size chart
A BJJ gi size chart does not read like a t-shirt label. You do not start from S, M or L, but from two measurements: your height in centimetres and your weight. It is the combination of the two that determines the right cut. A tall, slim practitioner and a short, stocky one can weigh the same without wearing the same size. Enter your measurements in the selector at the top of the page: it cross-references both and gives you the size that fits.
Sizes A0 to A4
Adult gis follow the A0 to A4 numbering, from smallest to largest. A0 suits lighter builds around 1.55 m (5’1″), A4 suits practitioners over 1.95 m (6’5″). In between, each size covers a height and weight range that you will find in the measurements table above. The L variants, such as A1L or A2L, offer the same width as a standard size, with a longer jacket and longer sleeves, designed for lean builds.
Between two sizes, which one should you take?
If your measurements fall between two sizes, the rule is simple: take the smaller size if you are stocky, the larger one if you are lean. A gi that is too big hangs loose and is easy to grip in a fight. A gi that is too short may fail the size check in competition. When in doubt, adjust on sleeve and jacket length rather than on weight.
Shrinkage in the wash
Our gis are pre-shrunk. The fabric has already gone through most of its shrinkage during manufacturing, so it will not get noticeably shorter with use. Wash it at 30 °C (86 °F) and let it air dry. Avoid the tumble dryer, the number one cause of a gi turning out too short. So choose your size on your current measurements, without allowing any margin for shrinkage.
Women’s cuts, F1 to F4
Women’s models follow their own numbering, from F1 to F4. The cut is tailored to the female build, more fitted at the waist and adjusted at the shoulders. Switch the selector to Women to get a recommendation on the right chart, and refer to the women’s size table.
Competition gis and IBJJF approval
In IBJJF competition, referees check sleeve length, jacket length and collar width before every match. Choosing the wrong size can get you turned away at the check. If you compete, make sure the jacket and sleeves meet the official measurements for your build, and go for a size that passes the check with your arms extended.
Still unsure about your size?
The selector and the table cover the vast majority of cases. If you are still hesitating between two sizes, write to us at contact@athletesonthemat.com with your height and your weight, and we will reply the same day.

Measurements chart
The measurements below are those of the garment, taken flat and after washing. They let you compare with a gi you already own, which remains the most reliable method.
Where the measurements are taken
Sleeve span
Cuff to cuff, jacket laid flat, sleeves extended.
Jacket length
From the base of the collar to the bottom hem, down the centre of the back.
Chest width
Armpit to armpit, jacket laid flat. This is the measurement that determines room across the shoulders.
Pant length
From the top of the waistband to the leg opening, along the outer seam.
Waist width
Width of the waistband laid flat. The drawstring allows adjustment either way.

|---|---|---|---|---|---|---|---|
| A0 | 150 to 163 cm | 50 to 63 kg | 150 cm | 72 cm | 55 cm | 93 cm | 50 cm |
| A1 | 160 to 173 cm | 62 to 74 kg | 160 cm | 76 cm | 58 cm | 98 cm | 51 cm |
| A1L | 173 to 181 cm | 65 to 75 kg | 167 cm | 78 cm | 59 cm | 100.5 cm | 51 cm |
| A2 | 177 to 183 cm | 77 to 85 kg | 169 cm | 80 cm | 60 cm | 103 cm | 53 cm |
| A2L | 180 to 190 cm | 82 to 92 kg | 173 cm | 82 cm | 62 cm | 105.5 cm | 55 cm |
| A3 | 184 to 195 cm | 88 to 102 kg | 175 cm | 84 cm | 64 cm | 108 cm | 58 cm |
| A4 | 195 to 205 cm | 102 to 130 kg | 183 cm | 88 cm | 67 cm | 113 cm | 61 cm |
The long cuts, A1L and A2L
They keep a width close to the standard size and lengthen the jacket, the sleeves and the pants. They are made for lean builds, at a comparable weight.
For example: at 178 cm and 72 kg, the A1L gives 2 cm more jacket and 2.5 cm more pant length than an A1, without widening the chest.
Between two sizes
Take the smaller one if you are stocky, the larger one if you are lean. If your weight exceeds the range for your height, go for the larger size: room across the shoulders matters more than length.
