My son just turned 7 and I think his height is 7.5-8 years (51 inches and 60 pounds). I ordered xs but it was too small so i ordered small and it fits great. He can even get away with an M with his sleeve rolled up. These shirts are great for outdoor sports and layering. My son loves everything under the armor but he loves this one too and I was able to get so many colors!
