    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]

    If the camera's angle were always the same, an ideal viewing distance could be easily calculated. However, the camera's horizontal angle varies as the focal length of its lens changes. If the camera's sensor has fixed dimensions, a shorter focal length (wide angle) lens captures a wider angle of view, requiring the viewer to sit closer to the ...

    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.
