Aspect ratio (image) The aspect ratio of an image is the ratio of its width to its height. It is expressed as two numbers separated by a colon, width:height. Common aspect ratios are 1.85:1 and 2.40:1 in cinematography, 4:3 and 16:9 in television, and 3:2 in still photography.
16:9. 8,294,400. 7680 × 4320. 8K UHDTV. 4320p. 33,177,600. Many of these resolutions are also used for video files that are not broadcast. These may also use other aspect ratios by cropping otherwise black bars at the top and bottom which result from cinema aspect ratios greater than 16∶9, such as 1.85 or 2.35 through 2.40 (dubbed ...
The aspect ratio of a geometric shape is the ratio of its sizes in different dimensions. For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side—the ratio of width to height, [1][2] when the rectangle is oriented as a "landscape". The aspect ratio is most often expressed as two integer numbers ...
The display aspect ratio (DAR) is the aspect ratio of a display device and so the proportional relationship between the physical width and the height of the display. It is expressed as two numbers separated by a colon (x: y), where x corresponds to the width and y to the height. Common aspect ratios for displays, past and present, include 5:4 ...
The 2:1 aspect ratio was first used in the 1950s (April 1, 1953) for one of the two flat formats that Universal Pictures developed (alongside 1.85:1), [1] the RKO Superscope format, [2] [3] and as an option in several other cinematographic formats. [4]
An image that is 2048 pixels in width and 1536 pixels in height has a total of 2048×1536 = 3,145,728 pixels or 3.1 megapixels. One could refer to it as 2048 by 1536 or a 3.1-megapixel image. The image would be a very low quality image (72ppi) if printed at about 28.5 inches wide, but a very good quality (300ppi) image if printed at about 7 ...
Widescreen. Classic television aspect ratio 4:3, and two wider ratios. Widescreen images are displayed within a set of aspect ratios (relationship of image width to height) used in film, television and computer screens. In film, a widescreen film is any film image with a width-to-height aspect ratio greater than 4:3 (1.33:1).
The aspect ratio of the pixels themselves is known as the pixel aspect ratio (PAR) – for square pixels this is 1:1 – and these are related by the identity: SAR × PAR = DAR. Rearranging (solving for PAR) yields: PAR = DAR / SAR. For example: A 640 × 480 VGA image has a SAR of 640/480 = 4:3, and if displayed on a 4:3 display (DAR = 4:3) has ...
