BMI Calculator

Do you know if you are at a healthy weight, underweight, overweight, or obese? Enter your weight and height into the BMI calculator to find out your current weight status.

  • Are you overweight or obese?  The advice in this section can help you make changes to achieve a healthier weight.
  • Are you at a healthy weight, but looking for ways to prevent weight gain? Small changes, like those discussed in this section, can help you make choices that prevent weight gain over time.
  • Are you underweight?  This site is designed for people trying to prevent excess weight gain, lose weight, or maintain weight loss. Being underweight also is a health risk. If you are classified as underweight, consult with your doctor to determine why you are underweight and learn what you can do to move toward a healthier weight.

Children and adolescents: The advice in this section is for adults. Because children and adolescents are growing, their BMI is plotted on growth charts for sex and age. You can learn more about BMIs for children and adolescents, and determine your child's weight status using the BMI calculator. If your child is overweight or obese, consult a health care provider to determine appropriate weight management for him or her.
