If you're looking at a 4K ultra-high-definition television, the formula changes a bit. Because of the increased resolution, the recommended ideal viewing distance is between one and 1.5 times the screen size. So, if you bought a 50-inch TV, it should be placed between 50 to 75 inches away..
Herein, what size does 4k matter?
The short answer is that between 5 and 6 ft. is the ideal viewing distance for a 55” or 65” Sony 4K Ultra HD TV. However, on a 55“, you can now sit as close as 3.6 ft and enjoy a visibly smoother and more detailed picture (e.g you won't see the individual pixels).
Furthermore, can you really tell the difference between 1080p and 4k? In short, it depends. The difference between 1080p and 4K is undeniable in that a 4K screen is capable of displaying four times the number of pixels as a 1080p screen. From a distance, it is virtually impossible for someone to tell the difference in quality between a 1080p and 4K screen.
Correspondingly, what size TV does 4k make a difference?
A 4K TV simply boosts that pixel count: Usually, 4K refers to a display resolution of 2160p, or 3,840 x 2,160 pixels. That's roughly four times larger than a 1080p picture, hence the term "4K." (Technically, 4K isn't the same as 2160p, but the technical differences are so minor that it doesn't really matter.)
