Uniqlo to Gap jeans size

The short answer

Uniqlo 28 is Gap 4 or 6 by the two brands' own charts.

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 Gap. Waist size sizes on the left, US numeric on the right.

Tinted rows change label or sit between two sizes. 2 sizes have no counterpart on the Gap chart. Read from the two charts only; no formula and no averaging.
