Pixel aspect ratio (PAR) refers to the ratio of the width of a pixel to its height in a digital image or video. It is an important concept in digital imaging and video production because it affects how images and videos are displayed on different screens and devices. In a square pixel aspect ratio, the width and height of each pixel are equal (1:1), which is typical for most modern displays, cameras, and video formats.
