How BMI is calculated
BMI (Body Mass Index) is a screening tool that estimates body fat based on height and weight.
BMI = weight (kg) ÷ height² (m²)
US units: BMI = 703 × weight (lb) ÷ height² (in²)
US units: BMI = 703 × weight (lb) ÷ height² (in²)
BMI Categories (WHO)
- Under 18.5 — Underweight
- 18.5–24.9 — Healthy weight
- 25.0–29.9 — Overweight
- 30.0+ — Obese
BMI limitations
BMI doesn't distinguish between muscle and fat, so athletes and very muscular people often register as "overweight" despite being healthy. It's a useful starting point, not a diagnosis. For a fuller picture, also check your body fat percentage and waist circumference.
