Aspect Ratio - Definition
Aspect Ratio is basically the ratio of width to height of a video picture. The two most common Aspect Ratios in home video are 4:3 (also known as 4x3, 1.33:1, or standard ratio) and 16:9 (16x9, 1.78:1, or wide-screen). All older TVs and computer monitors had the squarish 4:3 shape, which was only 33 percent wider than it was high. Today, 16:9 is the native aspect ratio of most HDTV programming. It is 78 percent wider than its height, or fully one-third wider than the older 4:3 standard ratio.
