Body Mass Index Calculator - Use this calculator to see if you are overweight, underweight, or healthy.


You should know what your personal BMI (Body Mass Index) values are in order to maintain good health. Body mass index (BMI) is widely accepted as the 'gold standard' for determining whether a patient is underweight or overweight. There are severe health risks in individuals with both high and low values. Check yours every year!

Body Mass Index (BMI) is a relationship between weight and height that is associated with body fat and health risk. The equation is BMI = body weight in kilograms/height in meters squared.

1. What Is Your Height?:  inches or   centimeters

Interesting Body Mass Index Facts



1. Bulimic patients prefer an ideal body with a BMI of 20, which is at the lower end of the 'normal' BMI range. However, the anorexic patient's ideal BMI is 15, which is on the border between the emaciated and underweight BMI categories.

2. Rapid growth during the first year of life is associated with increased Body Mass Index at the age of 6 years in both genders. In boys, high intake of protein in infancy could also contribute to childhood obesity.

3. Television viewing leads to a subsequent increase in Body Mass Index percentiles and overweight in adolescence. Adolescents who watched more than 2 hours of television a day were twice as likely to be overweight at follow-up as adolescents who watched less than 2 hours.

4. High waist circumference (WC) greater than or equal to 99 cm and Body Mass Index of greater than or equal to 28 kg/m2 are risks for stroke in older men but not in older women.
