A1F Gi Size: Height, Weight and Who It Fits

By All Around3 min readUpdated

Short answer: A1F fits 163–170 cm (5′4″–5′7″) and 54–64 kg (119–141 lb). It is the Fitted cut of A1: the trimmer cut — same lengths, less room through the body.

Against a plain A1 it is -6 cm jacket chest, -4 cm trouser waist. Everything else is identical to A1: jacket wingspan, jacket length, trouser length.

Where these sizes start, stop and overlap. Bands that share a weight range but not a height range are the ones people get wrong.

How to know it's you

If gis hang off you — shoulder seams past your shoulders, a jacket you can wrap a long way across — you have been buying for your height and ignoring your build. That is what A1F fixes.

Is A1F you?

Two numbers and we’ll tell you straight, including when the answer is a different size.

The finished gi, measured flat

Wingspan is cuff to cuff, jacket length is collar to hem, chest is laid flat. These are the numbers the size is cut to, not an estimate from the chart.

If A1F is not quite it

Step down to A0F or up to A2F if the band is wrong on weight. If the problem is that one half of you is a different size from the other, order it that way: a jacket in one size and trousers in another is a normal order here. About one gi in ten we shipped between 31 July and 29 September 2026 went out that way, and the mixed-size gi guide shows how to pick the pair.

And if no combination on the chart works, custom sizing is $189 and is cut to your measurements.

Size has nothing to do with legality, but fit does. The IBJJF measures sleeve and trouser length against your wrist and ankle with the arm extended, and a gi that is too short fails at weigh-in. The full requirements cover colour, fabric and the measurement rules.

Jacket: 162 cm wingspan cuff to cuff, 76 cm collar to hem, 48 cm chest laid flat. Trousers: 94 cm long with a 50 cm waist. Measured on the finished garment.
