there are different sizes of films that are used on different movie projectors after shooting on corresponding movie cameras... they are 18mm, 35mm, 70mm etc... the bigger the size of the frame of film the larger would be the screen that could be used with adequate resolution...
70mm is the size of the frame of the film...

70 mm film (or 65 mm film) is a wide high-resolution film gauge, of superior quality to standard 35 mm motion picture film format. As used in camera, the film is 65 mm wide; for projection 2.5 mm are added along each outer side of the perforations for magnetic strips holding six tracks of surround sound, although more recent 70 mm prints now use digital sound encoding; however, the vast majority of 70 mm prints predate this technology. Each frame is five perforations tall, with an aspect ratio of 2.20.
A 70 mm film frame is not only twice as wide as a standard frame but also has greater height. Shooting and projecting a film in 70 mm therefore gives more than twice the image area of non-anamorphic 35 mm film with no loss of quality.
