Comparing:
110 Pocket Film Cartridge
220 Roll Film (Double-Length Medium Format)

110 Film (introduced by Kodak in 1972 for the Pocket Instamatic system) is a subminiature drop-in film cartridge containing a 16.0 mm wide single-perforated film strip with a 13 × 17 mm frame format (approx. 1/4 the area of 35mm). Featuring integral supply and take-up chambers with backing paper, it requires no rewinding.

220 Film (standardized under ISO 732, introduced in 1965) is a double-length medium format roll film that yields twice the exposures of 120 film (24 exposures at 6×6 cm, 20 exposures at 6×7 cm). By eliminating the backing paper along the body of the film (retaining paper only at the black leader and trailer), twice as much film fits onto the same 25mm spool.
