Typography (from the Greek words τύπος (typos) = form and γραφή (graphe) = writing) is the art and technique of arranging type in order to make language visible. 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. In modern times, typography has been put into motion—in film, television and online broadcasts—to add emotion to mass communication.
Typography is performed by typesetters, compositors, typographers, graphic designers, art directors, comic book artists, graffiti artists, clerical workers, and anyone else who arranges type for a product. Until the Digital Age, typography was a specialized occupation. Digitization opened up typography to new generations of visual designers and lay users, and David Jury states that “typography is now something everybody does.”
