Aspect Ratio

What is Aspect Ratio?
The aspect ratio of an image is its displayed width divided by its height (usually expressed as "x:y" or "x×y). The older format for analog TV was 4:3, while the standard format for HDTV (both HD signals and HDTVs) is 16:9 or 1.78:1 (approximately 1.78" wide for every 1" high), while film directors can choose from any of the available film ratios. The most common formats for movies are 2.35:1, 2.40:1, and 1.85:1, which is very close to the 1.78:1 of HDTV.
