BMI Calculator

Check your Body Mass Index and understand your health range.

Educational estimate only — not medical advice. BMI is a rough population-level screen of weight for height and cannot tell muscle from fat, so it can mislabel muscular athletes, older adults, children and pregnant women. It is not a diagnosis — treat it as one signal alongside waist measurement, body composition and a doctor's assessment.
