My boy is 549 inches tall and weighs 50 pounds and usually wears a size 6 on most brands. However, I ordered these shorts in your size and they were huge, not just big but huge. So I sent them back and got a size 4 because the shorts are so cute and you can't beat the price. Let me just say that even a size 4 is too big for him, he easily fits a size 3 with little room to grow. And I would suggest ordering three sizes down to fit your child well. Also, the shorts are very cute, seem to be of good quality and very affordable, but the size is too big.
