A lettering scale for regulating the width and spacing between letters, which is used in conjunction with a straight edge guide is provided, and includes a generally planar, transparent member having first and second straight edges disposed in perpendicular relationship. A plurality of equally spaced parallel, visible guidelines are provided on the transparent member and are disposed in parallel relationship with the first straight edge. The spacing between the first straight edge and the nearest visible guideline of the array is equal to the spacing between each guideline of the array. After the drawing of horizontal guidelines, the width and spacing between letters can be regulated by the drawing of guide points, using the lettering scale. More particularly, in operation of the subject lettering guide, after a first guide point is drawn adjacent the first straight edge of the planar member, the member may be shifted in a direction perpendicular to the first straight edge by slidably moving the second straight edge along a straight edge guide until one of the visible guidelines is in register with the first guide point. Thereafter a second guide point can be drawn adjacent the first straight edge such that the second guide point is accurately spaced from the first guide point. In this manner, a plurality of guide points corresponding to the strokes of the letters may be drawn and thereafter interconnected to provide accurately sized and spaced letters.
