Age (months) Head Circumference (cm) Head Circumference Percentile Growth Chart Explanation and Clinical Context Head circumference percentile assessment is a tool used to evaluate head growth in infants and children as part of routine pediatric monitoring. Measurement reflects brain and skull development, giving clinicians insights into neurologic growth patterns. Interpretation typically refers to growth standards provided by the World Health Organization where percentile curves represent distribution in a healthy child population.

A value around fiftieth percentile suggests average growth. A value below third percentile can suggest microcephaly while values above ninety seventh percentile may indicate macrocephaly. Interpretation should always consider overall clinical context including gestational age birth history nutritional status developmental progress and familial head size.

Growth should be assessed longitudinally since a single point can be misleading. Persistent deviation above or below normal may warrant further evaluation including neuroimaging or referral to specialists.
