The area of sign faces enclosed in frames or cabinets is determined based on the outer dimensions of the frame or cabinet surrounding the sign face (See Figure 2).
Only one side of a backed sign is counted in determining the area of sign faces. Where the two sides are not of equal size, the larger of the two sides is used for the determination of sign area (See Figure 3).
For freestanding and projecting signs that contain multiple cabinets on one structure and oriented in the same direction, the modules together are counted as one sign face (See Figure 4).
The maximum surface area visible at one time of a round, three dimensional, or three or more sided sign is counted to determine sign area.
Signs On a Base Material.
When a sign is on a background panel and attached without a cabinet, such as a wood board or Plexiglas background panel, the dimensions of the background panel are to be used.
When signs are constructed of individual elements attached to a building wall, the sign area is determined by calculating the area of an imaginary rectangle drawn around the sign elements (See Figure 5). Sign elements will be measured as one unit when the distance between the elements is less than the dimension of the smallest element (See Figure 6).
Painted Wall Signs.
Painted wall signs are measured by drawing an imaginary rectangle around the edge of each of the sign elements. Sign elements will be measured as one unit when the distance between the elements is less than two times the length of each element (See Figure 6). Visible wall area includes windows and doors, but not openings such as loading entrances.
Awnings and Marquees.
When signs are incorporated into awnings, the sign area is determined by computing the area of an imaginary rectangle drawn around the sign face. When the ends of awnings or marquees are parallel and contain sign faces, only one side is counted in addition to the sign face area on the front.
