Our kids sizes run small. Go by height and weight, not the number on the label.

14 XL 12–13 4'8"–5'0" 84–100 lb 29–31"

Height and weight beat age. Two kids the same age can be a full size apart.

Between sizes? Go up. Rashguards give less than a normal shirt.

Cut fuller through the chest than our long sleeve — don't assume the set matches.
