WHO classifies BMI 18.5–24.9 as healthy weight. Under 18.5 is underweight, 25–29.9 is overweight, 30+ is obese.
BMI is a useful screening tool but does not account for muscle mass, age, or ethnicity. Consult a doctor for a full health assessment.
You can switch between metric (kg, cm) and imperial (lbs, ft/in) using the toggle above.
