Gap to Reformation jeans size

The short answer

Gap 10 is Reformation 29 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 Gap size read across to Reformation. US numeric sizes on the left, Waist size on the right.

Tinted rows change label or sit between two sizes. Read from the two charts only; no formula and no averaging.
