Most modern newspapers are in one of three sizes

Broadsheets: 600 mm by 380 mm (23½ by 15 inches), generally associated with more intellectual newspapers, although a trend towards “compact” newspapers is changing this. Tabloids: half the size of broadsheets at 380 mm by 300 mm (15 by 11¾ inches), and often perceived as sensationalist in contrast to broadsheets. Examples: The Sun, The National Enquirer, The National Ledger, The Star Magazine, New York Post, the Chicago Sun-Times, The Globe. Berliner or Midi: 470 mm by 315 mm (18½ by 12¼ inches) used by European papers such as Le Monde in France, La Stampa in Italy, El Pais in Spain and, since 12 September 2005, The Guardian in the United Kingdom. Newspapers are usually printed on inexpensive, off-white paper known as newsprint. Since the 1980s, the newspaper industry has largely moved away from lower-quality letterpress printing to higher-quality, four-color process, offset printing. In addition, desktop computers, word processing software, graphics software, digital cameras and digital prepress and typesetting technologies have revolutionized the newspaper production process. These technologies have enabled newspapers to publish color photographs and graphics, as well as innovative layouts and better design.
To help their titles stand out on newsstands, some newspapers are printed on coloured newsprint. For example, the Financial Times is printed on a distinctive salmon pink paper, and the Italian sports newspaper La Gazzetta dello Sport is printed on pink paper. Sheffield’s weekly sports publication derives its name, the “Green ’Un”, from the traditional colour of its paper, while L'Équipe (formerly L’Auto) is printed on yellow paper. Both the latter promoted major cycling races and their newsprint colours were reflected in the colours of the jerseys used to denote the race leader; thus, the leader in the Giro d'Italia wears a pink jersey.
