A film format is a technical definition of a set of standard characteristics regarding image capture on photographic film, for either stills or movies. It can also apply to projected film, either slides or movies. The primary characteristic of a film format is its size and shape.

In the case of motion picture film, the format may also include audio parameters (though often not). Other characteristics usually include the film gauge, pulldown method, lens anamorphosis (or lack thereof), and film gate or projector aperture dimensions, all of which need to be defined for photography as well as projection, as they may differ.

^(A) Unless otherwise noted, all formats were introduced by Kodak, who began allocating the number series in 1913. Before that, films were simply identified by the name of the cameras they were intended for.^[5]

For roll holder means film for cartridge roll holders, allowing roll film to be used with cameras designed to use glass plates. These were spooled with the emulsion facing outward, rather than inward as in film designed for native roll-film cameras. Types 106 to 114 were for Eastman-Walker rollholders, while types 50 to 54 were for Graflex rollholders.

The primary reason there were so many different negative formats in the early days was that prints were made by contact, without use of an enlarger. The film format would thus be exactly the same as the size of the print—so if you wanted large prints, you would have to use a large camera and corresponding film format.

Roll film cross-reference table[link]

Before WWII, each film manufacturer used its own system of numbering for the various sizes of rollfilms they made. The following sortable table shows the corresponding numbers. A blank space means that manufacturer did not make film in that size. Two numbers in one box refers to films available with different numbers of exposures, usually 6 and either 10 or 12. Spool length is measured between inner faces of the flanges; several films of the same image size were available on different spools to fit different cameras.
