My son is 10 years old. He weighs 98 pounds and is 4feet 6inches tall. What is the recommended weight for his height?

Body Mass Index (BMI) is a number calculated from a person's weight and height. However, there is some other information that the Centers for Disease Control and Prevention request for in their BMI calculator.

You can calculate your son's BMI by visiting their site. The web address is: BMI—Body Mass Index: Child and Teen Calculator | DNPA | CDC

Hope this answers your question!
