|An aspect ratio is the relationship between the width and the height of
a screen image. Virtually all sound films until 1953 were at a ration of 1.37:1, which is to
say, slightly wider than they were tall - a modest rectangle. Since the television ratio is
1.33:1, very little is lost when an older film is shown on television. (Even films shot in
the later standard ratio of 1.66:1 don't suffer too badly when viewed on a television.)
In the 1950s, however, Hollywood's attempt to lure people away from their television sets and back into theaters led to a battle of screen sizes, beginning with CinemaScope, which was more than twice as wide as it was high at a ratio of 2.35:1.
Today, most films are shot and shown in a ratio of 1.85:1; since this has become the "standard," such films are no longer thought of as "widescreen." Below you will see the range of screen ratios along with which processes use them.
