Where does a given height fall at this age?
Enter a height in centimetres, or in feet and inches, to see its percentile in the CDC reference table above for 20-year-old girls. The calculation runs in this page and sends nothing anywhere.
Enter a height between 137.2 cm and 189.0 cm.
Percentiles come from the CDC L, M and S parameters published on the same row as the table above (Sex=2, Agemos=240 (completed month 240 band)). A percentile is a position in that reference distribution for children of the same sex and age band; it is not a forecast, a diagnosis, or an assessment of any individual.
How common is a given height at this age?
Each row below converts a whole-step height to centimetres and places it against the nine percentiles published in the CDC table above. No value is interpolated: the comparison is read straight off that table.

What these numbers imply
The figures below are not published directly by the CDC. Each one is calculated from the official stature-for-age and weight-for-age tables so that this page answers questions the raw dataset leaves open. Values differ for every age and sex.
| Measure | Value | How it was derived |
|---|---|---|
| Spread between 3rd and 97th percentile | 24.4 cm | At this age the middle 94% of girls fall between 151.1 cm and 175.5 cm. A wider spread means age alone explains less. |
| Share of adult median height reached | 100.0% | The 50th percentile at this age is 163.3 cm; the CDC table ends at age 20 with a 50th percentile of 163.3 cm. |
| Difference from boys at the same age | -13.5 cm | The 50th percentile for girls is 13.5 cm shorter than the 50th percentile for boys at this age. |
| Median weight and resulting BMI at this age | 58.2 kg · BMI 21.8 | Combining the 50th percentile of weight (58.2 kg) with the 50th percentile of height (163.3 cm) from the CDC weight-for-age and stature-for-age tables. |
These are population reference statistics only. They describe how a group of children of this age and sex is distributed, and say nothing about any individual child.
How to read this table
For this table, the percentile is a position in the cited reference distribution for children of the same sex and completed age band. The 50th percentile is the median: about half of the reference observations are lower and half are higher. A percentile is not a forecast, target, diagnosis, or measure of an individual child’s health. Measurement method and the reference chart used can change the reported position.
Measurement: CDC reports standing stature for this age band.
