What should a 13 year old girls body mass index be?

According to the Centers for Disease Control and Prevention (CDC), a healthy body mass index (BMI) for a 13-year-old girl is between 18.5 and 24.9. This means that a 13-year-old girl who is 5 feet tall should weigh between 82 and 110 pounds. A girl who is 5 feet 4 inches tall should weigh between 90 and 125 pounds. A girl who is 5 feet 8 inches tall should weigh between 98 and 140 pounds.

It is important to note that BMI is just one measure of health. Other factors, such as body composition, physical activity, and overall health, should also be considered when assessing a child's health.

If you are concerned about your child's weight, talk to your doctor.
