    en.wikipedia.org/wiki/Aspect_ratio_(image)

    As an example, the film Gladiator was released to theaters in the 2.40:1 aspect ratio. It was filmed in Super 35 and, in addition to being presented in cinemas and television in the Original Aspect Ratio (OAR) of 2.40:1, it was also broadcast without the matte, altering the aspect ratio to the television standard of 1.33:1. Because of the ...

    The horizontal to vertical ratio of each pixel. Storage aspect ratio (SAR) The horizontal to vertical ratio of solely the number of pixels in each direction. [note 1] Display aspect ratio (DAR) The combination (which occurs by multiplication) of both the pixel aspect ratio and storage aspect ratio giving the aspect ratio as experienced by the ...

    en.wikipedia.org/wiki/List_of_computer_display...

    A widely used de facto standard, introduced with XGA-2 and other early "multiscan" graphics cards and monitors, with an unusual aspect ratio of 5:4 (1.25:1) instead of the more common 4:3 (1. 3:1), meaning that even 4:3 pictures and video will appear letterboxed on the narrower 5:4 screens. This is generally the native resolution—with ...

    For example, the constant π may be defined as the ratio of the length of a circle's circumference to its diameter. The following list includes a decimal expansion and set containing each number, ordered by year of discovery. The column headings may be clicked to sort the table alphabetically, by decimal value, or by set.

    Once seen as an "exotic" aspect ratio, [1] since 2009, it has become the most common aspect ratio for televisions and computer monitors, and is also the universal standard image format for the universal 1080p, 2160p and 4320p formats. 16:9 or "sixteen-nine" is the universal widescreen standard format [2] and Wide-aspect Clear-vision.

  7. Ratio - Wikipedia

    en.wikipedia.org/wiki/Ratio

    The ratio of width to height of standard-definition television. In mathematics, a ratio (/ ˈ r eɪ ʃ (i) oʊ /) shows how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).

  8. Display aspect ratio - Wikipedia

    en.wikipedia.org/wiki/Display_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.

  9. Aspect ratio - Wikipedia

    en.wikipedia.org/wiki/Aspect_ratio

    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 separated by a colon (x:y), less commonly as a simple or decimal fraction. The values x and y do ...
