55-inch TV
The ideal distance is about 6 ft 2 in. Sit between 5 ft 6 in and 7 ft 5 in for a cinematic picture. At those distances a 4K panel shows no visible pixel structure, so resolution is not the limit; picture size is.

How we got these numbers
A 55-inch 16:9 screen is 47.9 inches wide and 27 inches tall. The distance recommendations come from viewing angle standards used in cinema design: SMPTE recommends the screen fill at least 30° of your horizontal field of view, and THX recommends 36°, with 40° widely used as the maximum for the best seat.
Converting those angles into distances for a 47.9-inch-wide screen gives 7 ft 5 in (30°), 6 ft 2 in (36°), and 5 ft 6 in (40°). The resolution limit uses visual acuity: 20/20 vision resolves about one arcminute, so past 3 ft 7 in the individual pixels of a 55-inch 4K panel merge together.
If you sit farther than 7 ft 5 in, consider a larger screen. If you sit closer than 5 ft 6 in, the picture will feel like an IMAX front row: some people love it, most prefer to step back or size down.
