BMI Calculator

The standard BMI categories are: Below 18.5 = Underweight, 18.5–24.9 = Normal, 25–29.9 = Overweight, 30+ = Obese. However, some health organizations recommend slightly lower cutoffs for South Asians (like Indians): Normal up to 22.9, Overweight from 23.

BMI = weight (kg) ÷ height² (m²). Example: 70kg and 170cm → 70 ÷ (1.70)² = 70 ÷ 2.89 = 24.2 (Normal range).

BMI is a useful screening tool but not perfect. It doesn't distinguish between muscle and fat. Athletes may have high BMI but low body fat. Elderly people may have normal BMI but high body fat. Consult a doctor for accurate health assessment.

Ideal weight is calculated to keep your BMI between 18.5 and 24.9. This calculator shows you the ideal weight range for your height.
