Body Mass Index Calculator

The body mass index (BMI) is an approximate measure of body fat. It is based on your height and weight.
  • A BMI between 19 and 25 is considered a normal amount of body fat.
  • A BMI between 25 and 29.9 is considered overweight.
  • A person is said to be obese if his or her BMI is 30 or higher.
The higher your BMI, the greater your risk for diseases such as diabetes, heart disease, arthritis, and certain cancers. If you are concerned about your BMI or just want more information, talk with your family doctor.

Body Mass Index (BMI)

BMI is a reliable indicator of total body fat, which is related to the risk of disease and death. The score is valid for both men and women but it does have some limits:

  • It may overestimate body fat in athletes and others who have a muscular build.
  • It may underestimate body fat in older persons and others who have lost muscle mass.
