| | 8mm Film Gauges |
 | | Super 8mm, as it normally is packaged now, is single width 8mm film with Super 8mm perforations, and comes in 50ft(15m) lengths in a plastic Kodak cartridge. |
 | | Double 8mm, called such because the film is 16mm's wide, with perforations that are identical in size and pitch to that of 16mm film....although with an extra perforation which is required since the 8mm frame is 1/4th that of a 16mm frame. |
 | | After processing, the film is slit down the middle yielding two lengths of 8mm width movie film, which are spliced together in their order of the first half in front, yielding a total length of projection footage in either 50ft(from 25ft spools), 100ft(from 50ft spools...now long discontinued in use), and 200ft (from 100ft spools). |
