How it works
- BMI = weight (kg) ÷ height (m)².
- Under 18.5 underweight, 18.5–24.9 healthy, 25–29.9 overweight, 30+ obese.
- BMI ignores muscle mass and body composition — it is a screening figure, not a diagnosis.
Frequently asked questions
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat and is less reliable for athletes, older adults, pregnant people and children. Treat it as a rough guide and speak to a doctor for personal advice.
