About BMI
BMI (Body Mass Index) is a simple screening measure calculated from height and weight. It does not directly measure body fat and does not account for muscle mass, age, sex, bone density or overall body composition, so it is not a complete picture of health on its own — athletes, for example, can show a higher BMI despite being lean and fit. Use this as a general reference and talk to a healthcare professional for a full assessment. Nothing you enter here is uploaded or sent anywhere; everything runs directly in your browser.
