Calculating BMI

What is BMI?

Body Mass Index (BMI) is a number calculated from a person's weight and height. BMI is a fairly reliable indicator of body  fatness for most people.

How is BMI used?

BMI is used as a screening tool to identify  possible weight problems for adults. However, BMI is not a diagnostic tool. For example, a person may have a high BMI, however, to determine if excess weight  is a health risk, a healthcare provider would need to perform further  assessments. These assessments might include skinfold thickness measurements,  evaluations of diet, physical activity, family history, and other appropriate  health screenings.

Interpretation of BMI for adults

For adults 20 years old and older, BMI is interpreted using standard weight
status categories that are the same for all ages and for both men and women.
The standard weight status categories  associated with BMI ranges for adults are shown in the following table.

BMI	Weight Status
Below 18.5	Underweight
18.5 – 24.9	Normal
25.0 – 29.9	Overweight
30.0 and Above	Obese

If your BMI is above 25.0, you should consult with your health care provider to determine if your excess weight is a health risk.
