About BMI

The Body Mass Index (BMI) Calculator can be used to calculate BMI value and corresponding weight status while taking age into consideration. BMI is a measurement of a person's leanness or corpulence based on their height and weight, and is intended to quantify tissue mass.

BMI Categories (Adults)

Classification BMI Range (kg/m²)
Severe Thinness < 16
Moderate Thinness 16 - 17
Mild Thinness 17 - 18.5
Normal 18.5 - 25
Overweight 25 - 30
Obese Class I 30 - 35
Obese Class II 35 - 40
Obese Class III > 40

Important Note

BMI is a useful indicator of health at the population level. However, the distribution of muscle and bone mass can vary greatly from person to person. BMI should be considered along with other measurements and factors rather than being used as the sole method for determining a person's healthy body weight.
