For viewing documents in A4 paper size (which has a 1.41:1 aspect ratio), whether in portrait mode or two side-by-side in landscape mode, 4:3, 2:3 or 16:10 fit best. For photographs in the standard 135 film and print size (with a 3:2 aspect ratio), 2:3 or 16:10 fit best; for photographs taken with older consumer-level digital cameras, 4:3 fits ...
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 "Cinemascope", "21∶9" etc.), while the standard horizontal resolution, e.g. 1920 pixels, is usually kept.
The 1280 × 1024 resolution is not the standard 4:3 aspect ratio, instead it is a 5:4 aspect ratio (1.25:1 instead of 1. 3:1). A standard 4:3 monitor using this resolution will have rectangular rather than square pixels, meaning that unless the software compensates for this the picture will be distorted, causing circles to appear elliptical.
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. The size of a screen is usually described by the length of its diagonal , which is the distance between opposite corners, typically measured in inches.
4:3 (non-square pixels) 1–4 bpp typical, 2 or 3 bpp common. WQVGA: Wide Quarter Video Graphics Array Effectively 1/16 the total resolution (1/4 in each dimension) of "Full HD", but with the height aligned to an 8-pixel "macroblock" boundary. Common in small-screen video applications, including portable DVD players and the Sony PSP. 480×272 ...
The 64:27 aspect ratio is the logical extension of the existing video aspect ratios 4:3 and 16:9. It is the third power of 4:3, whereas 16:9 of widescreen HDTV is 4:3 squared. This allows electronic scalers and optical anamorphic lenses to use an easily implementable 4:3 (1.3 3) scaling factor.
The most common large format is 4 in × 5 in (10 cm × 13 cm), which was the size used by cameras like the Graflex Speed Graphic and Crown Graphic, among others. Less common formats include quarter-plate (3.25 in × 4.25 in (8.3 cm × 10.8 cm)), 5 in × 7 in (13 cm × 18 cm), and 8 in × 10 in (20 cm × 25 cm); the size of many old 1920s Kodak cameras (various versions of Kodak 1, 2, and 3 and ...
Common aspect ratios used in film and display images. The common film aspect ratios used in cinemas are 1.85:1 and 2.39:1. [1] Two common videographic aspect ratios are 4:3 (1. 3:1), [a] the universal video format of the 20th century, and 16:9 (1. 7:1), universal for high-definition television and European digital television.
