FAQ
How is BMI calculated?
BMI uses height and weight (metric or imperial). The result is placed in a standard category band for educational reference only.
Is BMI a medical diagnosis?
No. BMI is a simple screening formula and does not account for muscle mass, pregnancy, or many health conditions. Speak with a clinician for personal advice.
Why might athletes get a “high” BMI?
Muscle weighs more than fat, so BMI can overstate risk for muscular people. Treat the number as one rough signal, not a full health assessment.
Is my data private?
Height and weight stay in your browser for the BMI math and are not sent to our servers.
