is the art and technique of arranging type, and sometimes modifying typeglyphs. Type glyphs are modified using a variety of illustration techniques. The arrangement of type involves the selection of typefaces, point size, line length, leading (line spacing), adjusting the spaces between groups of letters (tracking) and adjusting the space between pairs of letters (kerning). Type design is a closely related craft, which some consider distinct and others a part of typography; most typographers do not design typefaces, and some type designers do not consider themselves typographers.
Typography is performed by typesetters, compositors, typographers, graphic designers, art directors, comic book artists, graffiti artists, and clerical workers. Until the Digital Age, typography was a specialized occupation. Digitization opened up typography to new generations of visual designers and lay users.
