Currently, the largest and most complete format for most Sunday strips, such as "Peanuts", is the half page. A few strips have been popular enough for the artist to insist on the Sunday strip being run in a half-page format, though not necessarily in a half-page size. "Calvin and Hobbes" was the first strip to do this, followed by "Outland" and later "Opus". "The Reading Eagle" is one of the few newspapers that still run half-page Sunday strips. Today, Slylock Fox & Comics for Kids is a popular example of a three tier half-page standard Sunday strip.
