About BMI Calculator
Calculate your Body Mass Index (BMI) using both WHO international standards and Asia-Pacific cutoffs recommended for Indian adults. For South Asians, the ICMR recommends lower cutoffs — overweight begins at BMI 23 (not 25) and obesity at 27.5 (not 30). Shows healthy weight range for your height, BMI category, and what it means for your health.
Body Mass Index estimates whether your weight is healthy relative to your height, but the standard WHO cutoffs were developed primarily from European and North American population data. Research from ICMR (Indian Council of Medical Research) and other Asia-Pacific studies has shown that Indians and other South Asians tend to develop metabolic complications like diabetes and heart disease at lower BMI thresholds than the WHO standard suggests, due to differences in body fat distribution. This led health bodies to adopt separate Asia-Pacific cutoffs — for example, 23 kg/m² is considered overweight in the Asia-Pacific classification versus 25 kg/m² under standard WHO guidelines. This calculator shows your BMI against both scales side by side so you can see how the classification changes depending on which standard is applied.

Expert note — India 2026
ICMR 2024 guidelines: For Indians, overweight = BMI ≥23 (not ≥25), obese Grade I = ≥25 (not ≥30). Standard WHO cutoffs underestimate cardiovascular and diabetes risk in South Asians.
Frequently asked questions
Is standard BMI accurate for Indians?
No. Indians develop metabolic complications at lower BMI. Indian overweight threshold is BMI ≥23, obese at ≥25 (ICMR 2024).
How is BMI calculated?
BMI = Weight(kg) ÷ Height²(m²). For imperial: BMI = 703 × Weight(lbs) ÷ Height²(inches²).
