There are a lot of different sizes (youth small, medium, large, etc.) depending on the age of your kid's market.
Typically, for ages 12 and up, they can get away with an adult small. The largest youth size is roughly the same size (it's a little shorter) as an adult small. If you have a market for younger than 12, then you would look to carry the various youth sizes.
