I tried to guess the size based on the reviews and was wrong. This is a tall boy belt (grade school I think K-6 or something) and you should choose a size around their shirt size (yeah it doesn't make sense but boys pants are usually waist size and these belts are sized S). , M, L, etc.). I got a medium for my sixth grader and it was too small. He wears a size L shirt and the size L belt was perfect. So think of a size based on the sizes they wear at that age and it should be close. The belt seems okay though.
