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.

135 Film (standardized under ISO 1007) is the most popular photographic film format in history, consisting of a 35.0 mm wide cellulose acetate or polyester strip with standard KS-1870 sprocket perforations housed in a light-tight metal cassette. Capturing standard 36 × 24 mm frames in 24 or 36 exposure lengths, it utilizes electrical DX-barcode contacts to auto-set ISO speed and exposure latitude.
