BMI Calculator for India
Uses the WHO Asia-Pacific cutoffs built for South Asian bodies, not the global scale most calculators default to — plus TDEE, body fat % and a macro plan in the same result.
What is BMI, and how is it calculated?
Body Mass Index (BMI) is weight in kilograms divided by height in metres, squared: BMI = weight (kg) / height (m)². It is a quick screen for whether your weight is in a healthy range for your height — not a diagnosis, and not a measure of body composition.
This calculator uses the WHO Asia-Pacific cutoffs, recommended for South Asian populations because South Asian bodies carry more visceral fat at the same BMI than the global averages the standard WHO scale was built from. That is why the same height and weight can read “Normal” on a generic calculator and “Overweight” here — this calculator is using the stricter, India-appropriate cutoff, not a different formula.
BMI categories (India / WHO Asia-Pacific)
| Category | BMI range |
|---|---|
| Underweight | Below 18.5 |
| Normal | 18.5 – 22.9 |
| Overweight | 23 – 24.9 |
| Obese | 25 and above |
What BMI does not measure
BMI cannot distinguish muscle from fat. A muscular person can score “overweight” despite low body fat, and someone with poor muscle tone can score “normal” despite high body fat. Use the calculator above for a fuller picture: it also estimates body fat percentage (via the US Navy method or an automatic estimate), lean body mass, daily calorie needs (TDEE), and a macro split for your goal.
Frequently asked questions
Why does this BMI calculator give a different result than a global one?
It uses the WHO Asia-Pacific cutoffs (Normal 18.5-22.9, Overweight 23-24.9, Obese >= 25) instead of the global WHO scale (Normal 18.5-24.9, Overweight 25-29.9, Obese >= 30). South Asian bodies carry more visceral fat at the same BMI, so international bodies including WHO and ICMR recommend the lower, India-specific cutoffs for this population.
What is the BMI formula?
Weight in kilograms divided by height in metres, squared: BMI = weight (kg) / height (m)^2.
Is BMI accurate for muscular or very lean people?
No. BMI cannot tell muscle mass from fat mass, so a muscular person can show as "overweight" despite low body fat, and a thin person with poor muscle tone can show as "normal" despite high body fat. That is why this calculator also estimates body fat percentage and lean body mass rather than stopping at BMI.
What should I do with my BMI result?
Use it as a starting point, not a verdict. Enter your details above to also get your TDEE (daily calorie needs), a macro split for your goal, and a protein supplement matched to your target intake.
