Find the optimal distance for a given screen. Example: for a 4K UHD screen 140 cm high (112 inches diagonal), the optimal distance is 140 × 1.6 = 224 cm. Find the right screen size. Example: for a 1080 HDTV used at a distance of 250 cm, you need to find a screen whose height is close to 250 / 3.2 = 78 cm (63 inches diagonally).
The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, typically measured in inches. It is also sometimes called the physical image size to distinguish it from the "logical image size," which describes a screen's display resolution and is measured in pixels. [1] [2]
A good rule of thumb is that your viewing distance should be about 1.5 to 2.5 times the TV's diagonal measurement. For a 50-inch TV, this means sitting between 75 and 125 inches away.

Perspective modifies the Z and Y coordinates of the object point, by a factor of D/(D–x), while binocular shift contributes an additional term (to the Y coordinate only) of s·x/(2·(D–x)), where D is the distance from the selected system origin to the viewer (right between the eyes), s is the eye separation (about 7 centimeters), and x is ...
