Growth charts use percentiles to show how a child's measurements compare to a reference population. For example:
5th Percentile: Indicates that the child is smaller than 95% of peers. 50th Percentile: Indicates that the child is average compared to peers. 95th Percentile: Indicates that the child is larger than 95% of peers.
Consistent growth along a particular percentile is generally a sign of healthy development. Significant deviations from established percentiles may require further evaluation.
