Letter Boards - Marquee Signs

There are two types of changeable letter boards. The most common letter board is mounted on the wall, has hinged doors for easy access and is about the size of a large TV. These letter boards are usually found inside schools, churches and other non-profit organizations. They are primarily used to display schedules and activities which change daily and sometimes weekly. Letter boards are also used in office building but as directories because business tenant information is rarely changed. The letter height is approximately one inch high. Visibility is not important since the viewer stands very close to the display.

The other type of letter board is an actual sign since it comes with changeable sign letters. This sign is made for outdoor use most often because of the larger display size and the larger letter size. Standard letter height for an outdoor display with changeable characters is approximately six to eight inches. Copy, or text, can be smaller or larger. This type of sign is often referred to as a changeable message sign. Its primary function is to convey a message. In the sign industry, the letter board sign is more aptly called a changeable letter sign. The main function of a letter board allows the user to change the characters. These type of signs are usually mounted onto a sign monument or a pole sign and has hinged doors for easy access. Changeable letter signs come in different sizes, large and small.
