This invention relates to a device for counting typographical characters on a page of typed material. The disclosed invention includes a transparent first member which may be oriented along a line of typographical characters. A transparent second member is slidably mounted in a perpendicular relationship to the first member. There are provided on the first member a plurality of sets of parallel lines, each of said sets being disposed from one end of said transparent first member to another end, the lines in each of said sets being consecutively numbered. There are further provided on the first member a plurality of sets of discrete spaces also disposed from one end of the transparent first member to another end, the width of the spaces corresponding to a particular type size, and the width of said spaces being uniform within a particular set, such that said spaces are superimposable upon a line of typographical characters of a particular type face. The transparent second member is provided with a plurality of sets of parallel lines disposed substantially from one end of the second member to another end of the second member. The lines within a particular set are consecutively numbered and the distance between the lines of a particular set correspond to a particular line spacing of typographical characters.
