The ratio of a display screen’s width to height is called the aspect ratio. It is typically expressed as x:y, like as 1.33:1, it is also frequently stated in public as 4:3 or 16:9. To offer more immersive video, the ratio progressively changed into a “wide format” with a wider width.
The ratio between a display’s width and height is referred to as the aspect ratio. It is typically described with two integers and a semicolon between them, such as x:y, after dividing the height by the width.
For example, a decimal place number is used to indicate the width to height ratio as 1.33:1.
* Instead of a decimal place value, the ratio on the market is expressed in specific proportions as 4:3 or 16:9.
The kinetoscope, the first film projector invented in 1889, introduced the 1.33:1 aspect ratio. Since then, a variety of aspect ratios with varied proportions have been introduced to meet a variety of production objectives, pushed by the development of wide format and image technologies to improve immersiveness.
