    As the cards are assumed to be installed in a vertical orientation, the usual meanings of height and width are transposed: A card might be 233.35 mm "high", but only 20 mm "wide". Height is measured in rack units, "U", with 1 U being 1.75 in (44.45 mm). This dimension refers to the subrack in which the card is to be mounted, rather than the ...

    To use AMCs in ATCA-systems a special carrier card known as hybrid or cutaway carrier is required to hold one Full-size Module or two Compact-size (see connectors below). Each height is paired with a width, single or double, describing how many carrier slots the board fills. A double width card allows more component space, but does not provide ...

    An "informative" (i.e. non-mandatory) annex [7] describes how an ID-000 sized card may be included in an ID-1 size card for processing (e.g. in an ID-1 reader), but with "relief areas around the perimeter of the ID-000 size card to allow it to be removed from the ID-1 size card without punching tools". An ID-1 size card containing an ID-000 ...

  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 .
