What is the aspect ratio?
A televisions aspect ratio is the ratio of a television screens width to height. The ratio is typically presented as whole numbers such as 4:3 or 16:9. The aspect ratio may also be divided out so 4:3 becomes 1.33 (4 divided by 3) and 16:9 becomes 1.78 (16 divided by 9). Traditional Direct View televisons (the type you’e been watching for the last fifty years) have an aspect ratio of 4:3. Television screens are always measured diagonally therefore a 50 inch 4:3 television is 50 inches diagonally, 40 inches wide and 30 inches high. An HDTV television has an aspect ratio of 16:9 therefore the screen is 16 inches wide for every 9 inches high.
