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]
For perspective, such a device at 15 inch (38 cm) screen size would have to display more than four Full HD screens (or WQUXGA resolution). The PPI pixel density specification of a display is also useful for calibrating a monitor with a printer. Software can use the PPI measurement to display a document at "actual size" on the screen.
The hemidiagon (1:½ √ 5) longer side is half the one of the root-5 rectangle and is produced by projecting the diagonal of half a square until it is perpendicular with the origin. Besides the square and the double square, the only other static rectangle included in the list is the hemiolion , which is produced by projecting 90° or 180 ...
It is expressed as two numbers separated by a colon (x:y), where x corresponds to the width and y to the height. Common aspect ratios for displays, past and present, include 5:4, 4:3, 16:10, and 16:9. To distinguish: The display aspect ratio (DAR) is calculated from the physical width and height of a display, measured each in inch or cm ...
The aspect ratio also affects the perceived size of objects on the screen. [5] The native screen resolution together with the physical dimensions of the graphics display can be used to calculate its pixel density. An increase in the pixel density often correlates with a decrease in the size of individual pixels on a display.

Apple is working towards bringing the foldable iPad, said to be the size of two iPad Pros when unfolded, to market around 2028, Bloomberg's Mark Gurman reported in the "Power On" newsletter on Sunday.
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
