A lettering guide for the tracing of alphanumerical characters comprises an elongate rectangular frame to be placed on a receiving surface such as a sheet of paper or cardboard, the frame accommodating a slider which is transversely shiftable in its opening to align a horizontal strip of the receiving surface with either of two sets of cutouts (e.g. for the tracing of capital and lower-case letters, respectively) formed in an elongate template. This template is longitudinally displaceable beneath a rectangular window of the slider in confronting parallel grooves of two bars of the latter extending along the major sides of the frame, the grooves lying below the level of the minor frame sides. A row of closely spaced indentations along an edge of the template are yieldably engageable by detents on the slider for indexing the template in selected working positions enabling a substantially uniform spacing of traced characters of different widths.
