110 is a cartridge-based film format used in still photography. It was introduced by Kodak in 1972. 110 is essentially a miniaturised version of Kodak's earlier 126 film format. Each frame is , with one registration hole. There were 24 frames per cartridge that occasionally enabled the user to capture an extra image due to production variations. 

The film is fully housed in a plastic cartridge, which also registers the image when the film is advanced. There is a continuous backing paper, and the frame number and film type are visible through a window at the rear of the cartridge. The film does not need to be rewound and is very simple to load and unload. It is pre-exposed with frame lines and numbers, a feature intended to make it easier and more efficient for photofinishers to print. 

Unlike later competing formats, such as disc and APS film, processed 110 negatives were returned in strips, without the original cartridge. The 110 cartridge was introduced by Kodak in 1972 with Kodak Pocket Instamatic cameras. The new pocket-sized cameras became immediately popular, and soon displaced competing subminiature cameras, such as the Minolta 16 series, from the market. The 110 film width is 16 mm. A four frame strip measures 111 mm.
