Standing height is the most important individual predictor of lung function indices and should therefore be measured with great care.
- The subject should have bare feet, and the heels together.
- Heels, calf, buttock and back should preferably touch the stadiometer.
- The investigators hands should then be cupped around the subject’s mandible and the face gently lifted so that the lower orbital level and the external auditory meatus are level.
- Record standing height in mm, refrain from rounding at this stage.
This procedure leads to very reproducible measurements, which may be up to 5 cm higher than non-standardized measurements.
