British comics typically differ from the American comic book. Although historically they shared the same format size, based on a sheet of 30 x 22 inch imperial paper, folded, British comics have moved away from this size, adopting a standard magazine size. Until that point, the British comic was also usually printed on newsprint, with black or a dark red used as the dark colour and the four colour process used on the cover. "The Beano" and "The Dandy" both switched to an all-colour format in 1993.
