Uniqlo to G-Star RAW jeans size

The short answer

Uniqlo 25 is G-Star RAW 24 by the two brands' own charts. 8 of 8 Uniqlo sizes land on a different label at G-Star RAW.

Both brands publish the body waist each size is cut for, so every row matches a waist, not a tag.

Every Uniqlo size read across to G-Star RAW. Waist size sizes on the left, Waist size on the right.

Tinted rows change label or sit between two sizes. 3 sizes have no counterpart on the G-Star RAW chart. Read from the two charts only; no formula and no averaging.
