Neck Circumference

Track neck size for body composition profiling and sleep apnoea risk screening.

Equipment

Flexible tape measure.

The protocol
  1. 01Client stands upright, looking straight ahead.
  2. 02Measure at the narrowest point of the neck, just below the larynx (Adam's apple).
  3. 03Keep tape horizontal and snug without compressing.
  4. 04Record to nearest 0.1 cm.
What to watch for
  • Tape too high (above the larynx) or too low (at the base).
  • Client tensing neck muscles or tucking chin.
Normative scoring

Men: >43 cm may indicate increased sleep apnoea risk. Women: >38 cm. Also used in US Navy body fat estimation formulas.
