The Development History of Movie Screen Ratio

As we all know, aspect ratio is ratio between width and height of the image. Nearly all the movies’ screen ratio was 1.33:1 which was also called 4:3 from the end of 19th century to 1950s. In 1953, Fox company introduced CinemaScope widescreen format which was adopted by many movie companies in the following few years. Panavision widescreen format appeared later and entered the mainstream in the markets.

Now, there are various kinds of aspect ratios in the movie field, but two of them have predominance: one is Academy Flat, 1.85:1, while the other is Anamorphic Scope, 2.35:1. People are more sensitive to the width than the height, so they feel more comfortable about widescreen than 4:3 video. In the movie theater, there are no doubt about the effect and visual impact of widescreen, especially with 3D or 4D effect.
