Questions about BMI & Health Calculator
Is BMI accurate?
BMI is a quick screening number, not a diagnosis. It doesn't know muscle from fat, so athletes can read 'overweight'. Use it as a guide and talk to a doctor about your health.
Is my data stored?
No. The numbers are worked out in your browser and are not saved or sent anywhere.
