Youth XS vs Youth S: What Is the Difference?

Youth XS fits a chest of 26 to 28 inches and a height of about 43 to 47 inches, while Youth S fits 28 to 30 inches and 47 to 52 inches. That is roughly two inches of chest room and four inches of length between them, which typically covers ages 4 to 6 in XS and 6 to 8 in S. Compare both against the full chart in our Kids Soccer Jersey Sizing Guide.

Who Fits Each Size

Youth XS suits petite 4 to 6-year-olds and smaller kindergarteners. Youth S fits average 6 to 8-year-olds. The overlap zone is the average 6-year-old, who may fit either. If your child is 47 inches tall or has a 28-inch chest, they sit exactly on the boundary. Height is the better tiebreaker here, because a Youth XS on a taller child means sleeves that ride up the forearms. See what size fits a 6-year-old for the full breakdown at this age.

Picking Between Them

Choose Youth XS for the best fit right now if your child is on the smaller side and the jersey only needs to last one season. Choose Youth S if they are growing fast or you want the jersey to survive a second season. Either way, do the two-minute measuring routine first, because guessing at this boundary is where most exchanges come from. And if you lean toward the bigger size, our sizing-up guide confirms when that is the right call.
