How to read this chart
A percentile compares your baby’s length with other girls of the same age. At the 50th percentile, half of healthy girls measure more and half measure less. Anything between the 3rd and the 97th percentile is within the usual range on the WHO chart.
The trend matters more than one number. A baby who stays near the same percentile line from visit to visit is growing steadily, whether that line is the 15th or the 85th. More in What percentile should my baby be?
