116 is a roll film introduced by Eastman Kodak in 1899 for 2½×4¼ inch negatives (nominally 6.5×11 cm). The film stock is 70mm wide: wider than that of 120 film.

In 1932, Kodak introduced 616 film. This has a slightly slimmer spool (originally metal rather than wood). Kodak discontinued both 116 and 616 in 1984.

With some ingenuity, 120 film can be used with cameras designed for 116 and 616, as can 70mm film. Remember that if you respool 120 film onto 116/616 spools and have it developed at a lab, you must ask for your 116/616 spools back. Otherwise they'll be thrown away!
