BMI Calculator

BMI categories (WHO, adults)

• Under 18.5 — Underweight
• 18.5 to 24.9 — Normal weight
• 25 to 29.9 — Overweight
• 30 and above — Obese

For many South Asian adults, health bodies suggest lower cut-offs (overweight from 23, obese from 27.5). BMI is a screening number, not a diagnosis — it does not account for muscle mass, age or body shape. Children and teens need age-specific BMI charts.
