Sign Letter Visibility

The height of your characters (letter size) is an important factor in designing your sign.

Another important factor is to use contrasting colors when designing your sign. Text color with a contrasting background can increase the impact and visibility of your sign by making your text stand out more. On the other hand, using a background color that is similar to your text color can make your text almost impossible to see at any distance. Some of the most visible text colors include black, red, and white, each most visible with a contrasting background color.

The font type that you choose can also impact the visibility of your text. Very thin fonts and script fonts can potentially decrease visibility. When choosing fonts, you want a bold style font that is easy to read with sufficient spacing between letters. You can test this by typing in a few words in a computer program at different font styles, colors, and sizes, and printing them out and posting them on a wall. Stand back and view them at different distances to see how all these aspects come into play in choosing the proper lettering for your sign.
