Health Vitals Checkup
Your body, by the numbers
Enter a few basics and see where several health numbers land against clinical ranges. These are general references, not medical advice — and no single number tells the whole story.
3 of 4 in a healthy range. Some markers sit outside the usual healthy range — context and a clinician matter more than any one number.

How this checkup works
BMI uses the standard weight-and-height formula against CDC categories; waist-to-height ratio against the widely used 0.5 threshold; body fat is estimated from BMI, age and sex (Deurenberg) against general ACE ranges; and activity against the CDC/WHO guideline of 150 minutes of moderate activity a week. These are general references and not a diagnosis — talk to a clinician about your health.

Frequently asked questions
Is BMI accurate for everyone?
No — BMI doesn't distinguish muscle from fat and can mislead for athletes, older adults and some groups. That's why we show it alongside waist-to-height and body fat, and none of it replaces a clinician.
What's the waist-to-height guideline?
Keeping your waist under half your height (a ratio below 0.5) is a simple, well-supported marker. It's a screen, not a diagnosis.
