Ok I bought a size 9-10 for my 7 year old: he is 51 inches tall and weighs 55 pounds. Slender build, I'll add if it's not obvious. these shirts fit him. I was confused, I checked the size on the internal unmarked print a few times just to make sure I was seeing it right. They would reach the size of a child and the color fades quickly.
