BMI Calculator
Calculate your Body Mass Index using WHO Asian/Indian cutoffs for accurate health assessment
Body Mass Index (BMI) is a quick screening measure that relates your weight to your height and helps flag whether you may be underweight, at a healthy weight, or carrying excess weight that raises the risk of diabetes, heart disease and pregnancy complications. Because Indian and other Asian bodies tend to develop these risks at a lower BMI, this calculator uses the WHO Asian cut-offs rather than Western ones, giving you a more realistic picture. Enter your weight and height in your preferred units to see your BMI, category and healthy weight range.

Why Asian/Indian BMI Standards?
Research shows that Asian and Indian populations have higher body fat percentages at lower BMI levels compared to Western populations. This means health risks like diabetes and heart disease occur at lower BMI values. WHO recommends using adjusted cutoffs for Asian populations.
Standard WHO Cutoffs
Normal BMI: 18.5 - 24.9
Overweight: 25 - 29.9
Asian/Indian Cutoffs
Normal BMI: 18.5 - 22.9
Overweight: 23 - 24.9
BMI Calculator — FAQs
Why does this BMI calculator use Asian / Indian cut-offs?
Research shows Indian and other Asian populations develop higher body fat and health risks like diabetes at a lower BMI than Western populations. WHO therefore recommends lower thresholds — normal 18.5-22.9 and overweight 23-24.9 — which this tool applies.
What is a healthy BMI for Indian women?
Using Asian cut-offs, a BMI between 18.5 and 22.9 is considered the healthy range with the lowest health risk. Below 18.5 is underweight and 23 or above signals increasing risk.
Is BMI accurate for everyone?
BMI is a useful screening tool but not perfect. It does not distinguish muscle from fat, so athletes may read high, and it does not capture where fat is stored. Waist circumference and body composition add a fuller picture.
How can I move towards a healthy BMI?
Gradual, sustainable changes work best: a balanced diet with adequate protein and fibre, regular physical activity, good sleep and stress management. A doctor or dietitian can tailor a safe plan for you.
Does BMI matter for pregnancy?
Yes. Pre-pregnancy BMI guides how much weight you should ideally gain during pregnancy and influences risks like gestational diabetes and high blood pressure. Discuss your target range with Dr. Neha Singhania.
