4K is a video standard that means that the frame is 4096 by 2304 pixels.
The 4k video refers to a video having a horizontal resolution of about 4000 pixels.
However, pixels are different sizes on different displays, so the answer is 58.74 pixels per inch on a 75-inch 4K television, for example, but 440.58 pixels per inch on a 5"-inch full HD smartphone screen.
There are several different standards. In general, 4K refers to a resolution of roughly 4,000 pixels wide and about 2,000 pixels high. That makes it the equivalent of four 1080p screens in height and length. Currently 4K is a catch-all term for a number of standards that are reasonably close to that resolution.
