Aspect ratios

The aspect ratio of a geometric shape is the ratio between its sizes in different dimensions. 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, when the rectangle is oriented as a “landscape”. The aspect ratio is expressed as two numbers separated by a colon (x:y). The values x and y do not represent actual width and height but, rather, the “relation” between width and height. As an example, 8:5, 16:10 and 1.6:1 are the same aspect ratio. In objects of more than two dimensions, such as Hyperrectangles, the aspect ratio can still be defined as the ratio of the longest side to the shortest side.
