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 Dutch word meaning "little quintal"; a measure that was a half of a barrel. 1 barrel = 4 firkins = 2 kilderkins [36 Imp. gal.] 1 hogshead = 6 firkins = 3 kilderkins [54 Imp. gal.]: 1 butt = 12 firkins = 6 kilderkins = 3 barrels = 2 hogsheads [108 Imp. gal.] {Beer bottles in South Africa were different from in other countries.}

The display aspect ratio (DAR) is calculated from the physical width and height of a display, measured each in inch or cm (Display size). The pixel aspect ratio (PAR) is calculated from the width and height of one pixel. The storage aspect ratio (SAR) is calculated from the numbers of pixels in width and height stated in the display resolution.
The diagonal screen size of a CRT television is limited to about 100 cm (40 in) because of size requirements of the cathode-ray tube, which fires three beams of electrons onto the screen to create a viewable image. A large-screen TV requires a longer tube, making a large-screen CRT TV of about 130 to 200 cm (50 to 80 in) unrealistic.
