A Visible Sign
Visibility is a critical factor in the effectiveness of your sign. Determine what the average viewing distance will be for your sign. Your sign should be easy to read and clearly distinguishable from the environment in which it is located. If you have issues such as inadequate space for large enough letters, remember that the elements of contrast and color can improve visibility and help viewers notice your sign and message.
A Readable Sign
Your sign should be designed in a way that quickly communicates your message. Emphasize keywords with strong typestyles and larger letters. Ideas should be organized intuitively with appropriate spacing. Graphic design elements can be used to promote fast recognition and awareness in communicating your message.
A Noticeable Sign
Consider your sign in the context of its environment. It should be highly noticeable amongst the distractions that may surround it. Contrast and color are important strategies to employ for this. The uniqueness of the design will also increase the likelihood that it will be noticed. For example, an unusual shape, relating to the establishment you are promoting, will get you noticed and convey an immediate message about your business.
A Legible Sign
A key factor in sign legibility is the typestyle used. Letters should be clearly distinguishable and easily interpreted. Many stylized typefaces are difficult to read, particularly at great viewing distances. Using trendy or artistic type fonts for sign text, other than as part of a logo, may give your sign a less professional look than a more traditional typestyle. Remember, you can always add creativity to your sign with graphic elements, shape, and color.
