The average head circumference of an infant at birth is typically around 13.5 to 14 inches (34 to 36 centimeters). By the time the infant reaches one year of age, the average head circumference increases to about 18 inches (46 centimeters). It's important to note that individual measurements can vary, and pediatricians often monitor growth patterns to ensure healthy development.
