The area of a sign shall be the product of its extreme vertical dimension and its extreme horizontal dimension.  In the case of projecting signs, the latter dimension shall be measured from the building face or pole or other support to which the sign is attached.  Where free-standing letters or insignia are used, the vertical and horizontal dimensions shall be measured between the outer limits of the letters or insignia composing the sign.
