Growth Charts Can Be Unreliable for Teenagers
It is not possible to provide healthy weight ranges for teenagers, according to the CDC. Weight ranges change sharply as height increases, and teenagers gain weight each month. Instead, doctors use assessments such as skinfold thickness to determine whether a teenager is overweight.
The average weight for a 14 year old boy is about 115 pounds, while the average weight for a 14 year old girl is about 109 pounds. However, rapid growth during puberty can make growth charts unreliable. If you are concerned about your weight, talk to your doctor.
