1. The size of any sign shall be computed by multiplying its greatest height by its greatest length, exclusive of supporting structures, unless such supporting structure is illuminated or is in the form of a symbol or contains advertising copy. In the case of signs that have no definable edges, such as raised letters attached to a building facade, the sign size shall be that area within a single continuous perimeter enclosing the extreme limits of the actual message or copy area.
2. The area of a sign shall be construed to include all lettering, wording and accompanying designs and symbols, together with the background, whether open or enclosed, on which they are displayed but not including any supporting framework and bracing which are incidental to the display itself.
3. Where the sign consists of individual letters or symbols attached to or painted on a surface, building, wall or window, the area shall be considered to be that of the smallest rectangle or other shape which encompasses all of the letters and symbols.
4. In computing square foot area of a double-face sign, only one side shall be considered provided both faces are identical. If the interior angle formed by the two faces of the double-faced sign is greater than 45 degrees, then both sides of such sign shall be considered in calculating the sign area and it shall be considered as a parallel sign.
5. If an establishment has walls fronting on two or more streets, the sign area for each fronting street may be computed and used. Each sign shall be placed on the frontage used in the computation. When a freestanding sign is used only one wall sign shall be allowed.
