Your son is 9 years old is 4 feet 7 inches tall and weighs 106 lbs how much over weight is he?

My Answer

No. Slightly (very slightly) underweight, actually. A boy that's 12 years & 7 months old standing 5 feet, 1 inch tall should weigh about 120 to 125 pounds, depending on frame. That's my assumption, of course and not based on factual evidence.
