Enter a length between 72.8 cm and 98.2 cm.
Percentiles come from the WHO L, M and S parameters published on the same row as the table above (Month=23). 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?

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 since birth | +36.4 cm | The 50th percentile at birth is 49.1 cm; at this age it is 85.5 cm. |
| Spread between 3rd and 97th percentile | 11.9 cm | At this age the middle 94% of girls fall between 79.6 cm and 91.5 cm. |
| Difference from boys at the same age | -1.4 cm | The 50th percentile for girls is 1.4 cm shorter than the 50th percentile for boys. |
| Median weight and resulting BMI at this age | 11.3 kg · BMI 15.5 | Combining the 50th percentile of weight (11.3 kg) with the 50th percentile of length (85.5 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.
