Small format
Small format means film formats for frame sizes ranging from 24x24mm of Rapid film to 40x40mm on 127 film, the latter can also be attributed as medium format, but 4x4cm slides can be displayed with small format projectors. The average small format frame size is that of type No. 135 film (35mm): 24x36mm
The original term for small format was miniature format. The cameras for smaller frame sizes are called subminiature cameras.
There are also 35mm cameras which belong to the subminiature category, i.e. the half-frame cameras which can shoot 72 24x18mm exposures on standard 36 exposure 35mm film cartridges. On the other hand the 4x4 cameras are sometimes categorized as medium format, thus being a category on the borderline between both categories. APS film standard was intended by the photo industry as replacement for the standard 35mm film but with frame size 30.2x16.7mm it's usually classified as subminiature film size.
