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.

A common size for LCDs manufactured for small consumer electronics, basic mobile phones and feature phones, typically in a 1.7" to 1.9" diagonal size. This LCD is often used in portrait (128×160) orientation. The unusual 5:4 aspect ratio makes the display slightly different from QQVGA dimensions. 160×128 (20k) 160 128 20,480 5:4 UNNAMED UNNAMED
On 2D displays, such as computer monitors and TVs, display size or viewable image size (VIS) refers to the physical size of the area where pictures and videos are displayed. 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.
This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g., red indicates a 4:3 ratio).
As a result of these size limitations, rear projection systems became popular [8] [9] as a way of producing television sets with a screen size larger than 12 inches. [10] Using a 3 or 4 inch monochrome CRT driven at a very high accelerating voltage for the size (usually 25,000 volts [ 11 ] though RCA did produce a larger five inch tube that ...
A 1997 study, which hypothesized that increases in screen size would give rise to increased feelings of presence, found that the content was more important than the screen size. The findings were that for commercials , action-adventure and reality programming an increase in the feeling of presence did correlate with increased size.
