Youth XL is the same as adult XS in chest width but shorter in every other measurement. In most brands, youth XL measures 34 to 36 inches in the chest with a 25-inch body length. Adult XS (where available) measures 30 to 32 inches in the chest with a 27-inch body length. The chest overlap only exists in boxy brands like Gildan and Hanes.
But most people asking "what size is youth XL" are really asking: what does it convert to in adult sizing? The answer is adult small.

Why Youth XL Is Not Exactly Adult Small
The chest measurements overlap, but the proportions are different in five ways:
Body length: Adult small is 2.5 to 3 inches longer. This is the biggest difference. Youth XL hits at the waist on a teenager. Adult small extends past the waist by 2 to 3 inches.
Shoulder width: Adult small has wider shoulders (18 to 19 inches vs 16 to 17 inches). On a teenager who has not filled out, adult small shoulder seams will hang past the natural shoulder point.
Sleeve length: Adult sleeves are 1 inch longer. On shorter arms, adult sleeves will look oversized.
Neck opening: Adult necklines are wider to fit an adult head and neck.
Torso taper: Adult shirts taper from chest to hem. Youth shirts are cut straighter for a teenager's body.

When to Stay in Youth XL
Stay in youth XL if the person's chest measures 36 inches or less and they are under 5 foot 6. The youth proportions (shorter body, narrower shoulders) will look right on a younger frame.
Youth XL is also the right call for team orders where you want all the youth shirts to have the same proportions and print placement. Mixing youth and adult cuts in the same order means the shirts will fit differently even with identical prints.
When to Move to Adult Small
Move to adult small when the chest exceeds 36 inches, height exceeds 5 foot 6, or youth XL is riding up above the waistband. The extra body length in adult small will look natural on a taller frame rather than too long.
If in doubt, go with adult small. A slightly long shirt looks like a normal shirt. A too-short youth XL looks like a shirt they outgrew. For the exact transition point by brand, read our Youth XL to Adult Small transition guide.
