My son is 47 inches tall and weighs 55 pounds. wears 6-7 or 7-8 clothes. Size 5-6 says 6T on label. They were too big for him, loose in the waist and below the knees. But they are tied with rope to support them and last more than one season. Also bought 13-14 for my 16 year old because he liked them. He is 5'4", weighs 125 pounds and has very low body fat. They are also loose in the waist but fit in length. Generally very happy with them.
