The circumference of the neck.
NeckCircumference
How to measure
Application
Used in collar and neckwear sizing, medical sleep apnoea screening, and personal protective equipment neck seal design.
Posture
Head level, looking straight ahead.
Landmark
Tape sits horizontally around the neck at the midpoint, just below the larynx (Adam's apple).
Tool
Tape measure.
Clothing
Remove all clothing from the neck area.
Common mistake
Measuring above the Adam's apple gives a narrower result. Position the tape just below it.
