DorsomLength
How to measure
Application
Used in chair backrest design to ensure lumbar and thoracic support extends the full length of the back from the seat surface to the base of the neck.
Posture
Sit upright on a firm, flat surface.
Landmark
Measured from the seventh cervical vertebra (C7) — the prominent bony bump at the base of the neck — down to the seat surface.
Tool
Tape measure.
Assistance
A second person should locate C7 and hold the tape end in place while measuring down to the seat.
Common mistake
Locate C7 by tilting the head slightly forward first to make the bump prominent, then return to upright before measuring.
