GPF mostly consists of traditional newspaper-style comic strips with occasional double-sized full-color "Sunday" comics. It updated daily up until July 2006 (7.75 years, a significant duration for a webcomic), when events surrounding the birth of Darlington's son forced its schedule to become more erratic. The comic is updated three times per week on Mondays, Wednesdays, and Fridays. Throughout the duration of its run, the comic has shifted between black and white and full color strips; it is updated only black and white.
