Normal 1.37:1 (20.9 x 15.2)

In 1889 Thomas Edison developed an early type of projector called a Kinetograph, which used 35mm film with four perforations on each side. The frame area was an inch wide and three quarters of an inch high, producing a ratio of 1.37:1. 1932 the Academy of Motion Picture Arts and Sciences made the Academy Ratio the standard Ratio, and was used in cinemas until 1953. Prior to the advent of Sound on Film in 1926, the Aspect ratio was 1.33:1.

Matted 1.66:1 (20.9 x 12.6)

Paramount was the first to break away from the traditional 1.37:1 aspect ratio when they released the film Shane in 1953. Photographed conventionally, it was projected with the top and bottom masked to achieve a 1.66:1 aspect ratio. Paramount established this aspect ratio for their conventional matted non anamorphic widescreen productions.

Matted 1.85:1 (20.9 x 11.3)

Another aspect ratio was used by Universal and Columbia Pictures where they cropped the 1.37 frame to an aspect ratio of 1.85:1. This format is also known as 'Spielberg-Format. It is still used for commercials, teasers and trailers in the cinema.


35mm scope formats

Cinemascope 1:2.35 (20.9 x 15.2)

The Cinemascope (most times called 'Scope') format uses special camera and projection lenses to optically squeeze and restore the image. Today, it is by far the most used picture format. The picture is squeezed to use as much surface as possible on the film to give greater sharpness, detail and stability opposed to the flat widescreen formats.
