CDC BMI Calculator

About CDC BMI Calculator

This calculator provides Body Mass Index (BMI) values and corresponding weight status categories according to the Centers for Disease Control and Prevention (CDC) guidelines. BMI is a person's weight in kilograms divided by the square of height in meters.

BMI Categories for Adults (CDC Standards):

Limitations of BMI:

While BMI is a useful screening tool, it does have limitations:

• 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
• It does not account for distribution of body fat, which is an important health indicator

For Children and Teens:

BMI is interpreted differently for children and teens. The CDC BMI-for-age growth charts take into account differences in body fat between boys and girls and across different ages.
