BMI Calculator FAQs

What is BMI?

BMI (Body Mass Index) is a value calculated from your weight and height. It is a screening tool that helps estimate your body fat and overall health risk.

Is BMI accurate for everyone?

BMI does not distinguish between muscle and fat mass. Athletes with high muscle mass may be misclassified as overweight. Use Body Fat Calculator or Waist-to-Height Ratio for better assessment.

What do WHO BMI categories mean?

Underweight: BMI < 18.5 | Normal: 18.5–24.9 | Overweight: 25–29.9 | Obese Class I: 30–34.9 | Obese Class II: 35–39.9 | Obese Class III: ≥ 40
