Head circumference

Information:

Definition:
Measurement of the circumference of the child's head. At its largest area (above the eyebrows and ears and around the back of the head). During routine check-ups, the distance is measured in centimeters and compared to previous measurements; normal ranges are based on age (weeks, months, and years).


This illustration shows the "sutures" or anatomical lines where the bony plates of the skull join together. These sutures can be easily felt in the newborn infant. The diamond shaped space on the top of the skull and the smaller space further to the back are often referred to as the "soft spot" in young infants.
