Determining proper head circumference is essential for selecting a well-fitting protective headgear. The process involves using a flexible measuring tape to ascertain the distance around the head at a specific point. The measurement provides a basis for comparing against helmet sizing charts.
Accurate headgear sizing enhances safety and comfort. Historically, ill-fitting helmets have contributed to increased injury risk during impact. A properly sized helmet improves impact absorption and minimizes movement during use, thereby offering superior protection. Furthermore, a comfortable fit encourages consistent use of safety equipment.
