The open sizing reference
A better way to know your gi size.
Every brand measures differently. GI Size gives those measurements a common language, so you can compare confidently before you buy.
Why it matters
An A2 is not always an A2.
Fit the gi to the person, not just the label. Use real garment dimensions, height and weight ranges to make the call.
