The aspect ratio of a geometric shape is the ratio of its sizes in different dimensions.

Example

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 ratio of height to width, when the rectangle is oriented as a portrait.

Expressing aspect ratio

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.

For example, 8:5, 16:10 and 1.6:1 are the same aspect ratio.
