People can be different heights and weights at different ages but the average height for an American boy of 16 years old is between 5 feet 3 inches to 6 feet 2 inches tall.
My brother was 6 feet tall at 16 years old and now he's 35 and is 6 feet 5 inches tall.
He's a pretty tall person and is much taller than his mom, dad and his sisters.
He seems to be the tallest in the family as of now.
