BMI Calculator
Check your Body Mass Index and healthy weight range.
Not medical advice. This calculator gives a general estimate. It cannot diagnose or treat any condition. Please speak to a qualified doctor about your health.
Body Mass Index (BMI) is your weight in kilograms divided by your height in metres squared. It is a quick screening number, not a diagnosis.

- Asian cut-offs: under 18.5 underweight, 18.5–22.9 normal, 23–24.9 overweight, 25 and above obese.
- WHO general cut-offs: under 18.5 underweight, 18.5–24.9 normal, 25–29.9 overweight, 30 and above obese.
South Asians tend to carry more body fat at a given BMI, which is why lower cut-offs are used for Indians.
Limits of BMI
BMI does not distinguish muscle from fat and ignores where fat is stored. Waist size, blood tests and a doctor’s assessment give a better picture.
