BMI Calculator
Body mass index is the quickest way to place your weight in context for your height. It is a starting point for a conversation, not a verdict on your health.
How it's calculated
Your BMI is your weight in kilograms divided by your height in metres squared. We show it against the standard WHO bands and the lower South Asian bands, since metabolic risk tends to begin earlier for South Asian bodies.
How to read your result
A BMI in the healthy band is reassuring, but the number cannot see muscle, or where you carry weight. A lean, muscular person can read as overweight, and a slim person can still carry risky visceral fat. Pair it with your waist measurement and how you feel.
Common questions
Research shows people of South Asian descent face higher metabolic risk at a lower BMI, so the WHO recommends lower cut-offs (overweight from 23). We show both so the number means more for you.
Method: Standard WHO bands, with WHO Asian-Indian cut-offs shown alongside.
