ASPECT RATIO & DIMENSION SCALE UNITS
4:3 Aspect Ratio & Dimension Scale Units
What are "units"? I use the term in the following chart to illustrate how much a particular dimension set is divided by its core elemental aspect ratio. For example, "NTSC Standard Resolution (720 x 540)" is "180" times larger than its 4:3 aspect ratio; that is 4 x 180 (width) = 720; and 3 x 180 (height) = 540.

16:9 Aspect Ratio & Dimension Scale Units
What are "units"? I use the term in the following chart to illustrate how much a particular dimension set is divided by its core elemental aspect ratio. For example, "HDTV 720 (1280 x 720)" is "80" times larger than its 16:9 aspect ratio; that is 16 x 80 (width) = 1280; and 9 x 80 (height) = 720.
