A typeface is a system in itself: a number of individual characters are designed to relate to each other to perform rhythm and consistency – a carefully balanced relation of form and counter form, black and white. Hermann Zapf once said: “I could try to draw each letter so that it stood in graceful relation to the other twenty-five.” 1 While less than 100 glyphs within a single font (a California Job Case consisted of 89 compartments) was common at the time of his statement (1965), over 1,000 has become a rather usual number of glyphs in recent years. What’s more, the demand on this system of relationships immediately increases with the designer’s decision to add further weights, widths or styles. Each glyph then has to successfully function in additional variations, which all share basic characteristics to form a harmonious and consistent visual system.
