American Eagle to Uniqlo jeans size

The short answer

American Eagle 8 is Uniqlo 28 or 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 American Eagle size read across to Uniqlo. US numeric sizes on the left, Waist size on the right.
