On 135 film, the typical cameras produce a frame where the longer dimension of the 24×36 mm frame runs parallel to the length of the film. The perforation size and pitch are according to the standard specification KS-1870. For each frame, the film advances 8 perforations. This is specified as 38.00 mm. This allows for 2 mm gaps between frames. Camera models typically have different locations for the sprocket which advances the film. Therefore, each camera model's frame may vary in position relative to the perforations. The film is approximately 0.14 mm thick.
