The vertical distance from the sitting surface to the top of the head.
SittingHeight
How to measure
Application
Used in vehicle headroom design, aircraft seating, and chair backrest height to accommodate the tallest seated users.
Posture
Sit upright on a firm, flat surface with your back straight but not arched. Look straight ahead.
Landmark
Measured from the seat surface to the highest point of the head.
Tool
Tape measure or rigid ruler held vertically.
Assistance
A second person should confirm the head is level and read the measurement from the side.
Common mistake
Imagine a string pulling the crown of your head upward. Slouching is the most common error and significantly reduces the result.
