BMI Calculator for Indians
Most BMI calculators use the global WHO scale — but that scale understates health risk for Indian and South Asian bodies. Here's the correct Indian classification, why it's different, and a free calculator that uses it.
For Indians, a healthy BMI is 18.5–22.9, overweight starts at 23, and obesity starts at 25 — not 25 and 30 as on the global WHO scale. This is the 2009 Indian Consensus Statement cutoff, now used across Indian clinical practice.
Why the same BMI means something different for Indians
BMI is just weight divided by height squared — it doesn't measure body fat directly. At the exact same BMI, South Asians carry more body fat, and specifically more visceral (abdominal) fat, than white European populations. That extra visceral fat drives type 2 diabetes and heart disease risk at BMI levels the global scale still calls "normal". WHO recognised this in 2004 and recommended lower thresholds for Asian populations generally; a 2009 consensus statement from Indian physicians set India-specific cutoffs even tighter.
Indian BMI classification vs the global (WHO) scale
| Category | Global (WHO) BMI | Indian BMI |
|---|---|---|
| Underweight | Below 18.5 | Below 18.5 |
| Normal | 18.5 – 24.9 | 18.5 – 22.9 |
| Overweight | 25.0 – 29.9 | 23.0 – 24.9 |
| Obese | 30.0 and above | 25.0 and above |

What is a healthy BMI for Indians?
18.5 to 22.9 is healthy for Indians — the same lower bound as the global WHO scale, but overweight starts at 23 (not 25) and obesity at 25 (not 30), per the 2009 Indian Consensus Statement on adult obesity.
Why is the Indian BMI cutoff different from the global BMI scale?
At the same BMI, South Asians carry more body fat — especially visceral fat — than white populations, and develop type 2 diabetes and heart disease risk at lower BMI thresholds. WHO recognised this in 2004 and recommended lower cutoffs for Asian populations; Indian physicians tightened it further in 2009.
Is BMI 24 overweight or normal for an Indian?
Overweight, under the Indian classification. The same BMI of 24 is still "normal" on the global WHO scale (which runs to 24.9), which is exactly why using the wrong scale understates risk for Indian users.
