Body Mass Index Calculation

- Are you over or underweight?

Calculation of body mass index (BMI) helps to understand the person's needs for healthy weight. It also can indicate the risk of serious health conditions associated with weight problems. The simple way to check your body mass index is to use calculators. All our BMI calculators may show categories such as underweight, healthy weight, overweight and obesity. They are available in two versions: standard (English units) and metric measures. Calculators on this page can be used for men and women 20 years and older.
