For a 65-inch screen, the distance increases to 77 inches, or 6.4 feet. For an 80-inch screen, it's 95 inches, or 7.9 feet. You can do the math in reverse if you're trying to select a screen size for a predetermined viewing distance: Viewing Distance x 0.84 = Screen Size.
In any case, viewing distance is as important as choosing the size or resolution of your TV (because all three are related), and so the next time you buy an HDTV, please take into consideration the viewing distance as well.
