Measured adult data
Body statistics without body judgment.
Explore measured adult height, weight, BMI, and waist distributions. Each tool identifies the reference population and explains what the number cannot tell you.
↕
Height percentile
Enter age and height in feet/inches or centimeters. Get an approximate percentile from measured NCHS data.
◉
Weight and BMI
Compare adult weight by age and calculate BMI while keeping the screening limits visible.
↔
Waist circumference
Compare a properly taken waist measurement with age-based percentiles.
What these tools do well
- Use in-person measurements rather than anonymous self-report.
- Compare with an age-specific reference group.
- Show an approximate percentile, not a pass/fail grade.
- Keep entries in the browser.
What they cannot determine
- Health, fitness, attractiveness, strength, or body composition.
- Whether a change is medically concerning.
- How your measurements compare outside the U.S. reference population.
- What your body ought to look like.
