The aspect ratio is the ratio of the width of a shape to its height when the width is larger than the height, i.e. the shape is positioned as a "landscape" rather than "portrait".
The aspect ratio is expressed as two numbers separated by a colon (x:y). A common misunderstanding is that x and y represent actual length and height. This is false, they actually represent the relation between width and height. As an example 8:5, 16:10 and 1.6:1 is the same aspect ratio.
It may be applied to two characteristic dimensions of a three-dimensional shape.

Famous quotes containing the words aspect and/or ratio:
“The percept is the reality. It is not in propositional form. But the most immediate judgment concerning it is abstract. It is therefore essentially unlike the reality, although it must be accepted as true to that reality. Its truth consists in the fact that it is impossible to correct it, and in the fact that it only professes to consider one aspect of the percept.”
—Charles Sanders Peirce (1839–1914)
“People are lucky and unlucky not according to what they get absolutely, but according to the ratio between what they get and what they have been led to expect.”
—Samuel Butler (1835–1902)
