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 .
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 ...
Pixel aspect ratio 2:1. A Pixel aspect ratio (often abbreviated PAR) is a mathematical ratio that describes how the width of a pixel in a digital image compared to the height of that pixel. Most digital imaging systems display an image as a grid of tiny, square pixels. However, some imaging systems, especially those that must be compatible with ...
Waist-to-height ratio: the average ratio for US college competitive swimmers is 0.424 (women) and 0.428 (men); the ratios for a (US) normally healthy man or woman is 0.46–0.53 and 0.45–0.49 respectively; the ratio ranges beyond 0.63 for morbidly obese individuals. [15]
Comparison of screen sizes by width, height, diagonal, area, and aspect ratio. On 2D displays, such as computer monitors and TVs, display size or viewable image size (VIS) refers to the physical size of the area where pictures and videos are displayed.
For comparison, the ratios are also given as a decimal number, which is the flag width divided by its height (e.g. a 2:3 flag has a decimal ratio of 3 / 2 = 1.5). Flags with irrational ratios have only a decimal approximation, and have the exact form given in the "Notes" column (which also includes additional information such as similar ...
The graphics display resolution is influenced by the aspect ratio, which is the ratio of the width to the height of the display. The aspect ratio determines how the image is scaled and stretched or cropped to fit the screen. The most common aspect ratios for graphics displays are 4:3, 16:10 (equal to 8:5), 16:9, and "21:9". The aspect ratio ...
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 ...
