Where should you measure an infant's head circumference?

Measuring an infant's head circumference at the widest area across the eyebrows is the most accurate method for assessing head growth and development. This specific location captures the maximum head diameter, which is crucial for evaluating normal development and identifying potential abnormalities.

The measurement is taken just above the eyebrows and around the largest part of the head, which generally includes regions above the ears and at the back. This method adheres to established guidelines for head circumference measurement to ensure reliability in tracking growth patterns during an infant's early months.

In contrast, measuring at the base of the neck or above the ears would not provide a true representation of head size, as these locations are not the widest points of the head. Similarly, measuring at the forehead's midpoint could yield inconsistent results, as it does not account for the total diameter of the head. Therefore, measuring at the widest area, right across the eyebrows, is essential for accurate monitoring of an infant's growth and development.
