Signs should be considered a component of the design concept for the site and building architecture. The size, proportion, and scale of signs contribute to the overall quality of a project when they can relate to building details rather than compete with them (e.g. signs which extend above the roof line, or cover architectural details, columns, or windows).
In most instances, signage should be designed in proportion with respect to its size, location, and background. For example, signs having size to background ratios of 1 to 4, or 1 to 3, tend to be in better proportion than signs having ratios of 1 to 1, or 1 to 100. Further, signs should not exceed 80% of their vertical/horizontal backgrounds.
The utilization of quality materials for signs is encouraged in all instances. Color and material selection for signs should be related to the color scheme and texture of the building or project materials rather than depend upon "high contrast" factors in order to be effective.
