One measure.
Not the whole you.
BMI compares weight with height. It does not directly measure body fat or distinguish muscle from fat. A clinician can interpret it alongside your health history, exam, and other findings.
Explore the CDC’s adult BMI guidance ↗| Underweight | Below 18.5 |
| Healthy weight | 18.5 to less than 25 |
| Overweight | 25 to less than 30 |
| Obesity | 30 or above |
Categories follow CDC guidance. The category uses the full calculation; the displayed BMI is rounded to one decimal place.

A little more clarity
How is BMI calculated?
Using metric measurements: weight in kilograms divided by height in meters squared. US measurements are converted to metric before calculation.
Does this result diagnose a health condition?
No. BMI is a screening measure, not a diagnosis. It is one part of a broader health assessment.
Can children and teens use this calculator?
This calculator uses adult categories for ages 20 and older. For ages 2 through 19, use the CDC child and teen calculator, which accounts for age and sex.
