A list of sign terminology.

*Indicates terms that are often linked to Interior Signage, though not exclusively so.

• ADA Signs*: Signs that meet the American Disability Act specifications for accessibility, which include placement, design, color, content, and style guidelines. Often these include signs with braille and ADA approved icons.
• Aesthetics: elements of signage that project a particular level of beauty and value, including aspects of design, color, form, and quality of craftsmanship that appeal to a viewer’s artistic sensibilities.
• Animated signs: a sign that uses changes in light and color to create the impression of motion, or that incorporates actual mechanical elements that move. Animated signs may achieve motion through the use of electrical power or by mechanical means, for instance wind currents. Signs that flash on and off give the impression of motion, but in animated signs, the motion is more integral to the design and message.
• Awning signs: sign mounted to a building so that it provides information while also serving as shelter. Or signage, usually a vinyl application, affixed to existing awnings.
• Backlighted letters: open-backed or translucent and lit from within or behind, that throws light back onto the support surface to create a halo effect around the letters. (Sometimes called silhouette or halo lettering.)
• Ballast: the electrified structure that secures and powers fluorescent lamps.
• Banners: portable signage made of a light, flexible material like cloth or vinyl that is hung or strung from hooks or cord. Often used to announce events and openings, banners function well for short-term signage and in-home use, or can be fabricated out of durable materials for long-term reuse indoors and out.
• Bench signs: lettering and imagery applied to the back section or other surfaces of public seating, for instance on park benches and bus-stop seating.
• Building fascia: the exterior wall of a building, rising from ground level to the roofline eaves and extending across the full width of the structure.
• Building mounted signs: signage hung from or affixed to the wall or roof of a building.
• Cabinet signs: the frame or external structure of a box-like sign that encloses the various functional elements of the design, whether electrical or dimensional components.
• Canopy signs: sign, like a marquee, constructed or affixed to a building in such a way that it serves as a canopy over the space below; Or a sign affixed to a canopy.
• Carved signs: signs made of wood or synthetic materials with lettering and graphics deeply gouged into the surface of the substrate. These incise carved elements are usually painted or gilded with 23K gold leaf.
• Changeable copy panels: a section of an otherwise permanent sign that allows the message to be amended, updated, or otherwise modified using track lettering or dry erase, etc. Popular uses include A-frames and menu boards.
• Changeable copy signs: signage structure and lettering that provides panel-support or letter tracks allowing full sign changes and updates. Popular for informational signage and announcements.

• Cost per thousand (CPM): the cost of bringing a message to the attention of a thousand viewers. CPM is calculated by dividing the cost of a given advertising medium by the number of individuals who will view or be exposed to the medium. Well-designed and displayed signage on buildings or on vehicles is seen by so many individuals on a daily basis that signage is considered one of the most cost-effective modes of advertising, with low CPM.

• Electronic message centers: signage that features changeable text and/or illustrations, using computer software or other technology to automate the messages delivery schedule.
