Enter a length in centimetres, or in feet and inches, to see its percentile in the WHO reference table above for 7-month-old girls. The calculation runs in this page and sends nothing anywhere.
Enter a length between 58.0 cm and 76.5 cm.
Percentiles come from the WHO L, M and S parameters published on the same row as the table above (Month=7). 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 length at this age?
Each row below converts a whole-step length to centimetres and places it against the nine percentiles published in the WHO 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 WHO. Each one is calculated from the official length-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 |
|---|---|---|
| Growth over the next 3 months | +4.2 cm | The 50th percentile rises from 67.3 cm to 71.5 cm over the following 3 months. Derived from adjacent rows of the same WHO table. |
| Growth since birth | +18.2 cm | The 50th percentile at birth is 49.1 cm; at this age it is 67.3 cm. |
| Spread between 3rd and 97th percentile | 8.7 cm | At this age the middle 94% of girls fall between 62.9 cm and 71.6 cm. |
| Difference from boys at the same age | -1.9 cm | The 50th percentile for girls is 1.9 cm shorter than the 50th percentile for boys. |
| Median weight and resulting BMI at this age | 7.6 kg · BMI 16.8 | Combining the 50th percentile of weight (7.6 kg) with the 50th percentile of length (67.3 cm) from the WHO weight-for-age and length-for-age tables. |
These are population reference statistics only. They describe how a group of infants 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: WHO reports recumbent length for children under age 2; the page title follows the common height-chart search phrase.
