Overview
Pixel aspect ratio (PAR) is width:height of individual pixels. Square pixels = 1:1. Display aspect ratio (DAR) is screen width:height. Essential for video processing and conversion.

Pro Tips
Web and modern computer displays strictly use square pixels (PAR 1.0).
DV NTSC (Standard Definition) has a PAR of roughly 0.91 (tall and thin).
DV PAL has a PAR of roughly 1.09 (short and fat).
Incorrect PAR settings in your editing software lead to images looking stretched or squashed on TVs.

Fun Facts
Formula: DAR = (Width × PAR) / Height; PAR = (DAR × Height) / Width
