BMI Calculator for Indians: Why the Standard Chart May Mislead You

BMI is the quickest health screening number there is — but the standard WHO chart can give South Asians a false sense of safety. Here's how to read your BMI correctly.

Get your number

The BMI calculator takes your weight and height and returns your Body Mass Index plus the healthy weight range for your height.

The standard categories

WHO classifies BMI under 18.5 as underweight, 18.5–24.9 as healthy, 25–29.9 as overweight, and 30+ as obese.

Why Indians need stricter cutoffs

Research shows South Asians develop higher body fat and cardiovascular risk at lower BMIs. Several Indian health bodies use tighter thresholds: overweight from BMI 23 and obese from 25. So a BMI of 24 — "healthy" on the WHO chart — may already carry elevated risk for an Indian adult. If yours is 23–25, discuss it with your doctor.

What BMI can't see

BMI doesn't distinguish muscle from fat. Athletes can read "overweight" while lean; a sedentary person can read "healthy" with high visceral fat. Waist circumference is a better risk signal: above roughly 90 cm for men and 80 cm for women in South Asian guidelines.

Use it as a trend

Recheck monthly under the same conditions. Pair BMI with the ideal weight calculator and BMR calculator, but treat all as informational. This is general information, not medical advice.
