Computer Monitors are typically measured and marketed by the diagonal length of the screen. The diagonal can be calculated by using the Pythagorean theorem; that is to take square root of the combined height squared plus the width squared.
left top corner to right bottom corner.
EDIT: Screen size is usually measured across the diagonal - as screens can be different shapes. Older screens are more square than the newer 'wide-screen' monitors. Measuring across the diagonal provides a 'standard' method of determining the screen size. Snakester1962 (Supervisor)
As i said above Left top corner to right bottom corner.....
Resolution is Measured in Pixels
The resolution of a monitor is measured in picture elements, or "pixels" for short. Pixels are tiny dots that display on a computer monitor in one of millions of colors, shades and hues. To the viewer, the many pixels in a computer monitor combine to form a viewable picture.
Vertical Measurements
The first consideration in measuring a monitor's resolution is the number of lines displayed on the monitor from top to bottom. While a traditional television display may consist of about 480 lines, higher resolution computer monitors squeeze at least 1080 lines onto the display.
Horizontal Measurements
Each of the many lines measured in Section Two above is comprised of hundreds or thousands of tiny dots (pixels). Generally, the number of pixels contained in a line is proportional to the number of lines in the monitor's display; more lines means more dots in each line.
Resolution is Measured in Horizontal x Vertical Pixels
When a monitor's resolution is described, the description generally consists of the number of dots (pixels) contained in each line followed by the number of lines on the monitor. For example, a 1600 x 1200 display would contain 1600 pixels per line and display 1200 lines. An older monitor that displays resolutions of 640 x 480 would display 480 lines containing 640 pixels each. By this measurement, the number of dots per line can be multiplied by the number of lines to identify the total number of pixels displayed by the monitor. Using the examples above, a 1600 x1 200 monitor would display 1,920,000 individual pixels. An older monitor with a resolution of 640 x 480 would display 307,200 individual pixels. Because the individual pixels combine to display a complete picture, a higher number of pixels generally means a clearer picture.
Diagonally. A 17'' monitor is 17 inches from the bottom left corner to the top right corner.
The size of a T.V. screen is measured diagonally. From the top left corner to the bottom right corner, vice versa.
From corner to corner, not including the bezel.
the size of a tv screen is measured diagonally from a one corner to the other i.e top left corner of screen to the bottom right cornber of the screen the size is given in inches.
with a tape measure
If you mean the screen size, then it is measured by the diagonal of the screen from corner to corner.
Lenth
screen size of any computer or tv screen is measured along the diagonal. so screen size 14 inches means that the length of the diagonal of the screen is 14 inches
it is measured in speed because of how fast it can transfer to the screen
Manufacturers measure monitors by screen size. The measurement is taken diagonally, from the bottom left of the screen to the top right corner of the screen.
Screen size is measured diagonally in inches between opposite corners of the screen.
The S4 mini has a screen size of 4.3 inches (measured diagonally) with 540x960 pixels.
Every screen I have ever heard of is measured from corner to corner. Televisions, LCDs, computer monitors, everything I know of. Always has been. Also, there is a difference is screen size and VIEWABLE screen. For example, if you have a 23" monitor, it may only be 21" viewable. Manufacturers market the total screen size, which is more than the viewable size.
Diagonally across the screen. (From top left to bottom right, or top right to botom left.)
This laptop features a standard 15.4" diagonally measured wide screen display as per the manufacturer.
The display size of the screen is measured on the diagonal. For instance, lower left hand corner to upper right hand corner. For the TV itself, the size will vary on the case design.
If you mean a TV's actual size, you measure the screen diagonally
