Film sizes and designations

Jump to: navigation, search

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. The longest-lived film size, type 120 introduced in 1901 by Kodak, has been continuously available for over 120 years.

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. Prior to this, films were identified only by the image size produced and the specific cameras the films fit. 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.

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. Only one other roll film size using the same sequential numbering system was introduced after that: size 130 introduced in 1916.

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. Initially, the leading "6" in these sizes was meant to indicate the number of frames on the roll; however, by the time these films came to market the length of film actually used on the rolls generally permitted more frames per roll, and the "6" became only an arbitrary means of distinguishing the film size. Kodak also introduced roll size 828 in the 1930s, which is a 35mm wide film with only one perforation per frame. The number 828 was chosen to represent "8" frames of "28"mm-wide (by 40mm long) images on a roll.

In Europe and Japan, many film sizes had alternative names; see also Japanese formats.

  1. 1.0 1.1 Agfa Ansco Photographic Materials catalogue, circa 1930 reproduced at Pierce Vaubel; p11. The number in the Agfa sizes gives the number of exposures, for the most part: in some cases this has been overtaken by the introduction of half-frame or square-format cameras (thus A8 is 127 film for 8 exposures 4x6.5 cm in Agfa's only 127 camera, the Billy 0). B2 (Kodak 120) and D6 film (Kodak 116) were for some reason made in both 6- and 8-exposure rolls.
