Our son is almost 6 years old and 48 inches tall and I bought him size L-7. It fits perfectly. The t-shirt looked great, just like the picture (some reviewers showed photos of t-shirts with small prints but ours was fine.) The material is not bad but not the best, the cotton felt a little thin to me . son liked it very much!
