Height Percentile Calculator
See exactly where your height stands. As you type. Uses the CDC LMS method (the same math behind clinical growth charts) for children and teens, and U.S. adult survey data for adults, with a live chart of where you sit and comparisons across 90+ countries.

Adult Height Percentile Chart (U.S.)
Wondering what percentile a given height falls into? The tables below show approximate percentiles for U.S. adults based on CDC/NHANES survey data, where the average height is about 5'9" for men and 5'4" for women.
Men
Percentiles are statistical estimates for adults aged 18+ and vary between surveys and countries. They describe how common a height is, not whether it is healthy.
How This Calculator Works
Children & teens: the LMS method
For ages 2–20, the calculator uses the CDC's published LMS parameters. The same method pediatric growth software uses. Instead of reading between chart lines, it computes an exact z-score for any age (including half-ages like 9.5) and converts it to a percentile.
- Exact percentiles, not chart approximations
- Age matters to the month, not the nearest year
- The 3rd–97th percentile band is the typical range
Data sources
- CDC Growth Charts (LMS), stature-for-age: ages 2–20
- CDC/NHANES surveys: U.S. adult height statistics
- International surveys: national average heights for the country comparison (estimates)
Results are statistical estimates for information only, not medical advice or a growth evaluation.
Frequently Asked Questions
How accurate is this calculator?
For ages 2–20 it computes exact percentiles from the CDC's LMS parameters, the same method used in clinical growth assessment. Adult percentiles come from CDC/NHANES survey data. Results are statistical estimates: measurement technique and the reference population both affect where you land.
What height percentile is 6 feet?
For adult men in the United States, 6 feet (183 cm) is around the 85th percentile, taller than roughly 85% of men. For adult women, 6 feet is above the 99th percentile. The adult tables above list percentiles for more heights.
Why does the calculator ask for sex instead of gender?
Growth references are built from measured male and female growth patterns, which differ during childhood and puberty. The calculator uses the reference that matches your biological sex because that is what the underlying data measures.
What's considered a normal height range?
Heights between the 3rd and 97th percentiles are generally considered typical. A single measurement matters less than the overall growth pattern. If you have concerns about a child's growth, a pediatrician can evaluate growth velocity over time.
