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.
The ideal optimum viewing distance is affected by the horizontal angle viewed by the camera capturing the image. One concept of an ideal optimal viewing distance places the viewer at a point where the horizontal angle subtended by the screen is the same as the horizontal angle captured by the camera.
