ASPECT RATIO

The 'aspect ratio' of a two-dimensional shape is the ratio of its longer dimension to its shorter dimension. It is also applied to two characteristic dimensions of a three-dimensional shape, especially for the longest and shortest 'axes' or for symmetrical objects (''e.g''. rods) that are described by just two measures (''e.g''. length and diameter). In such cases, the aspect ratio may evaluate to a value less than one (''e.g''. consider very short and very long rods).
In aviation, the aspect ratio of aircraft tapered wings is found by dividing the square of the wing span by the standard mean chord (SMC).
The term is most commonly used with reference to:

★ aspect ratio (image)

★ computer display standard

★ paper size

★ pixel aspect ratio

★ tire sizing

★ aspect ratio (wing) of aircraft or birds

★ aspect ratio (optics) of a lens diameter or longest dimension relative to its thickness
