A method and apparatus for displaying more than one font on a limited dot matrix display device are disclosed. In addition to displaying characters in a standard font based on using all pixels in a five by seven pixel matrix, a custom font set based on a reduced size pixel matrix is used for character display. A maximum of four columns and six rows of pixels, i.e., a four by six matrix, are used for the custom font out of the five columns and seven rows of pixels which are available. In further embodiments of the invention, the pixels which are not used to create a character may be used to add a background characteristic. Thus a reverse video font or underlining font may be created. In an additional embodiment, a box can be placed around a word by using the underline font in conjunction with placing a vertical line immediately before the first character and immediately after the last character of a word to be placed in a box.
