How the BMI Calculator Works
BMI (body mass index) is your weight in kilograms divided by the square of your height in metres. It is a quick way to see whether your weight is in a healthy range for your height.
Indians and other South Asians develop diabetes and heart disease at a lower BMI than Europeans, so doctors in India use the Asia-Pacific ranges: under 18.5 is underweight, 18.5 to 22.9 is healthy, 23 to 24.9 is overweight and 25 or more is obese.

Is BMI accurate for everyone?
BMI does not separate muscle from fat. Athletes can show a high BMI while being healthy, and older adults can show a normal BMI with too little muscle. Your waist size and body fat give a fuller picture.
Why is the Indian obesity cut-off 25 and not 30?
Studies in Asian populations show that the risk of diabetes, high blood pressure and heart disease starts rising at a lower BMI. That is why Indian guidelines treat a BMI of 25 or more as obese.
Can children use this calculator?
No. Children’s BMI is read against age and sex on a growth chart. Use the Child Growth / BMI calculator instead.
