Height

Measure standing height for BMI calculation and body proportion assessment.

Equipment

Stadiometer or wall-mounted height measure.

The protocol
  1. 01Ask the client to remove shoes, heavy outer clothing, and hair accessories.
  2. 02Client stands with back against the stadiometer — heels, buttocks, upper back, and head touching the surface.
  3. 03Ensure the head is in the Frankfort horizontal plane (the lower edge of the eye socket is level with the ear canal opening).
  4. 04Lower the headpiece to rest firmly on the top of the head, compressing hair.
  5. 05Record height to the nearest 0.1 cm at the end of a normal inhalation.
What to watch for
  • Client standing on tiptoes or with heels raised.
  • Head not in the Frankfort plane — tilting up inflates the reading.
  • Not compressing thick or voluminous hair.
How to read the result

Height does not change in adults — it is a fixed baseline that powers BMI and waist-to-height ratio. Record it once and reuse it; there is no score to beat.
