In the 1930s Kodak introduced two revised versions of existing roll sizes, which used the same size film but were rolled onto smaller diameter spools: 616 is a variation of size 116, and 620 is a variation of size 120. Only one other roll film size using the same sequential numbering system was introduced after that: size 130 introduced in 1916. When standardized roll film sizes were introduced by Kodak, the sizes were assigned to all of the film sizes produced by Kodak at that time, using numbers 101 through 129, numbered sequentially in order of the date when the original film size was first used. This made it difficult or impossible to cross-reference films made by different manufacturers for different cameras, especially as the number of amateur cameras available on the market greatly expanded toward the end of the first decade of the twentieth century. Prior to this, films were identified only by the image size produced and the specific cameras the films fit. ![]() Kodak's standardized roll film size numbers were gradually introduced starting in 1912, and first appeared as a complete list in the 1914 Kodak Condensed Price List. The longest-lived film size, type 120 introduced in 1901 by Kodak, has been continuously available for over 120 years. ![]() ![]() Roll film and cassette- or cartridge-based films have been available in many different standardized sizes to fit specific cameras and film holders or backs.
