Height Percentile Calculator
Calculate height percentile with personalized inputs and reference ranges for healthy values.
What Is Height Percentile?
Height percentile tells you where your height ranks compared to the general population of the same age and sex. A height at the 75th percentile means you are taller than 75% of people in your reference group. Pediatricians use growth percentile charts (from the CDC or WHO) to track children's development, while adult height percentiles provide context for how your stature compares to population norms. This calculator shows your percentile based on US population data.
What Percentiles Mean for Children
For children, percentiles track growth over time rather than defining a single ideal height. A child consistently at the 25th percentile who stays on that curve is growing normally. A child who drops from the 75th to the 25th percentile over several visits may need evaluation. The CDC growth charts cover ages 2–20, and the WHO charts cover birth to age 5. Pediatricians use these tools at every well-child visit to identify potential growth concerns early.
Adult Height Percentiles
US adult men average 68.9 inches, which is 5'8.9" or 175 cm, per the CDC's 2021-2023 measured survey data. US adult women average 63.5 inches, 5'3.5" or 161 cm. Height follows a bell curve, so most people sit within a few inches of the average, and the median lands very close to the mean for both sexes.
Adult Height Percentile Table
The values below come from CDC measured survey data for US adults aged 20 and over. Measured height runs slightly shorter than self-reported height, because people tend to round up.
| Percentile | Men | Women |
|---|---|---|
| 10th | 5'5" | 5'0" |
| 25th | 5'7" | 5'2" |
| 50th (median) | 5'9" | 5'3.5" |
| 75th | 5'11" | 5'5" |
| 90th | 6'1" | 5'7" |
These are approximate conversions of the percentile bands in the CDC anthropometric tables. A man at 6'1" is taller than roughly 90% of US men; a woman at 5'0" is shorter than roughly 90% of US women. Enter your own height in the calculator above for an exact percentile against this distribution.
