2. Sizing and Measurement
Accurate measurement is essential for proper fit and effectiveness. Please follow these instructions to determine the correct size and depth for your cervical collar.
Measuring Instructions:
- Neck Circumference: Measure around the fullest part of your neck.
- Collar Depth: Measure the straight line distance from the sternal notch (the dip at the base of your throat) to the base of your mandible (jawbone). This measurement helps determine the appropriate collar depth (Narrow, Average, or Wide).
