Common Measurement Mistakes
Measuring standing height with shoes on
✕
Can overstate height by close to an inch.
Skipping seated shoulder height entirely
✕
Assuming standing height alone determines roller placement.
Forgetting the reclined footprint
✕
Only measuring the chair's seated dimensions against the room.
Comparing to the exact edge of a spec
✕
A chair rated “up to 6'4″” performs best with room below that ceiling, not sitting precisely at it.
