80 inches is the diagonal measurement. The aspect ratio will be 16 horizontal by 9 vertical.

Using Pythagorean's theorem we can determine:

  • diagonal^2 = horizontal^2 + vertical^2
  • diagonal^2 = 16^2 + 9^2
  • diagonal^2 = 256 + 81 = 337
  • diagonal = 18.36

Using these ratios:

  • 80 inches diagonal / 18.36 = horizontal / 16 = vertical / 9
  • 80 inches diagonal = horizontal * 18.36 / 16 = vertical * 18.36 / 9
  • 80 inches diagonal : 69.72 inches horizontal : 39.22 inches vertical

So the dimensions of an 80 inch flat screen television will be a bit larger than 70 inches by 40 inches.
