Actually, the rule of thumb is to align your eyes (straight ahead) to about 3/4 up the height of viewable area of the screen. That is, about 1/4 of the screen is above eye-level, the rest is below and this should apply to any reasonable screen size.
By this formula, a 55-inch-diagonal screen has an ideal viewing distance of 65 inches, or 5.4 feet. 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.
