Youth XL and adult medium are not the same size. Youth XL fits kids ages 14 to 16 with a 32 to 36 inch chest. Adult medium fits a 38 to 40 inch chest. That is a 4 to 6 inch difference in the chest alone, plus 3 to 4 inches in body length. They are not close.

The confusion usually comes from the word "XL." Parents hear "extra large" and assume it must be close to an adult size. It is not. Youth XL is the biggest kids size, but it is still a kids shirt. The proportions, shoulder width, sleeve angle, and body length are all designed for a teenager, not an adult.
Who Fits Youth XL
Youth XL works for kids ages 14 to 16 who measure 32 to 36 inches in the chest and stand roughly 58 to 66 inches tall. These are typically eighth graders through sophomores who have outgrown youth large but have not filled out enough for adult sizing to make sense.
Youth XL is the bridge size between youth and adult. It overlaps with adult small in chest width (both hover around 34 to 36 inches in boxy brands) but is 2 to 3 inches shorter in body length. That shorter length is what makes youth XL fit a teenager's proportions better than adult small.
Which Size to Order
If a kid is outgrowing youth XL, the next size up is adult small, not adult medium. Youth XL to adult medium skips a full size. The correct progression is youth XL to adult small to adult medium.
For the detailed breakdown of how youth XL and adult small compare, read our Youth XL vs Adult Small guide. That is the critical transition point.
