The body mass index (BMI) calculator is designed for an adult with an average body type. It is not designed for pregnant women or children.
The BMI calculator is not necessarily indicative of your overall health. It does not take into account your frame (for example, the broadness of your shoulders or the size of your pelvis) or your muscle mass. If you are concerned about your weight, talk to your doctor.
To determine the body mass index of someone who is 2 to 19 years old, use the Centers for Disease Control and Prevention's BMI calculator for children and teens.
