BMI Calculator with Indian Cut-Offs
Nearly every BMI calculator online tells an Indian the same thing it tells a Swede. That is a problem: at the same BMI, South Asians carry more body fat and face higher diabetes and heart risk, which is why India uses lower thresholds than the WHO global scale.
This calculator leads with the Indian cut-offs and shows the global ones beside them, so you can see both answers and understand why they differ.
This is an estimate for healthy adults, not medical advice. If you are pregnant, breastfeeding, or managing a medical condition, speak to your doctor before acting on it.
How it works
BMI is your weight in kilograms divided by the square of your height in metres. The number is the easy part; the thresholds are what matter. Indian guidance counts 23 and above as overweight and 25 and above as obese, where the WHO global scale uses 25 and 30.
BMI = weight in kg / (height in m)^2
A worked example
A person 175 cm tall weighing 72 kg has a BMI of 23.5. On the Indian scale that is overweight. On the WHO global scale the same number sits comfortably inside normal. Same body, two different answers, and for an Indian the first one is the more useful warning.
What it cannot tell you
- BMI does not measure body fat. A muscular person can read as overweight while carrying very little fat.
- It says nothing about where fat sits, and abdominal fat carries more risk than the same weight elsewhere. Waist circumference adds what BMI misses.
- It is not designed for pregnancy, for people under 18, or for the very elderly.
Frequently asked
- What is a healthy BMI for Indians?
- Indian guidance places the normal range at 18.5 to 22.9, with 23 to 24.9 counted as overweight and 25 and above as obese. These are lower than the WHO global thresholds of 25 and 30.
- Why are Indian BMI cut-offs lower?
- At the same BMI, South Asian populations tend to have a higher proportion of body fat and greater cardiometabolic risk than European populations. The WHO Asia-Pacific consultation and Indian guidelines both reflect this.
- My BMI says overweight but I go to the gym. Is it wrong?
- Possibly. BMI cannot tell muscle from fat, so trained people often read high. Waist measurement and body-fat estimates give you a fuller picture.
- Is BMI still worth using?
- As a quick population-level screen, yes. As a verdict on one individual, no. Read it as one number among several, not a diagnosis.
