1. Stature

　

	Definition:	The vertical distance from the floor to the vertex (i.e. the crown of the head)Applications: As a cross-referencing dimension for comparing populations and estimating data; defines the vertical clearance required in the standing workspace; minimal acceptable height of overhead obstruction such as lintels, roofbeams, light fitting, etc.

	Corrections:	Shoes as above; 25mm for a hat; 35mm for a protective helmet. A few design applications call for supine or prone body length (in which the subject lies on his back or front, respectively). Such a position lengthens the adult body by approximately 15mm.
	Notes:	(i) In children under 2 years, who cannot stand unaided, crown-heel length is the nearest equivalent dimension. The child must be stretched out in a supine position and prevented from wriggling.
		(ii) If you ask an adult person to tell you their height, you must expect them to overestimate by an average of about 25mm.
