It depends on the teenager's height and body composition. According to the Centers for Disease Control and Prevention (CDC), the healthy weight range for a 15-year-old girl who is 5 feet tall is 95 to 135 pounds. For a 15-year-old girl who is 5 feet 4 inches tall, the healthy weight range is 105 to 145 pounds. However, it is important to note that these are just general guidelines and that each teenager's individual weight will vary depending on their genetics, activity level, and other factors. If you are concerned about your child's weight, it is best to talk to a healthcare professional.
