  2. Photo print sizes - Wikipedia

    en.wikipedia.org/wiki/Photo_print_sizes

    The alternative Super series, denoted SnR, nR Plus or nR+, has an aspect ratio of 3∶2 (or as close as possible) and thus provides a better fit for standard 135 film (35 mm) at sizes of 8 inches or above. 5R is twice the size of a 2R print, 6R twice the size of a 4R print and S8R twice the size of 6R. 4D/6D is a newer size for most consumer ...

  3. Image resolution - Wikipedia

    en.wikipedia.org/wiki/Image_resolution

    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 inches wide. The number of photodiodes in a color digital camera image sensor is often a multiple of the number of pixels in the image it produces, because information from an array of color ...

  4. Display size - Wikipedia

    en.wikipedia.org/wiki/Display_size

    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. It is also sometimes called the physical image size to distinguish it from the "logical image size," which describes a screen's display resolution and is measured in pixels. [1] [2]

  5. Pixel aspect ratio - Wikipedia

    en.wikipedia.org/wiki/Pixel_aspect_ratio

    Storage aspect ratio is the ratio of the image width to height in pixels, and can be easily calculated from the video file. Display aspect ratio is the ratio of image width to height (in a unit of length such as centimeters or inches) when displayed on screen, and is calculated from the combination of pixel aspect ratio and storage aspect ratio.

  6. Aspect ratio (image) - Wikipedia

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

    In motion picture formats, the physical size of the film area between the sprocket perforations determines the image's size. The universal standard (established by William Dickson and Thomas Edison in 1892) is a frame that is four perforations high. The film itself is 35 mm wide (1.38 in), but the area between the perforations is 24.89 mm × 18 ...

    The resolutions are equal, and the size of the 1600 resolution edges is within a tenth of an inch (16-inch vs. 15.89999"), presenting a "picture window view" without the extreme lateral dimensions, small central panel, asymmetry, resolution differences, or dimensional difference of other three-monitor combinations.
