Aspect ratio (image)From Wikipedia
The aspect ratio of an image is its displayedwidth divided by its height (usually
expressed as x:y or xy, with thejoining colon or multiplication symbolarticulated as the preposition by orsometimes to). For instance, the aspect
ratio of a traditional television screen is 4:3,or 1.33:1.High-definition television and Europeandigital television use an aspect of16:9, orabout 1.78:1. Aspect ratios of 2.39:1 or
1.85:1 are frequently used incinematography, while the aspect ratio of async-sound 35 mm film frame is 1.37:1 (alsoknown as Academy Aperture ratio). Silent
films, which used the full frame, were shotin 1.33:1.
