A monitor's size is the distance (usually measured in inches) from corner to corner, diagonally across the screen.
This applies to widescreen and normal/full screen monitors.
However the manufacturer's specified size might be slightly more than the actual 'viewable size' for a couple of reasons:
1. They tend to round-up. So what they might call a 24 inch monitor might actually only be 23.5 inches.
2. A CRT monitor's size traditionally includes the casing around the screen, for reasons dating back to the invention of the technology decades ago. This doesn't apply to lcd flat panel monitors.
See the related link(s) for a more indepth guide and a tool for getting an approximate measurement of a monitor screen size.
By Measuring the monitor diagonally this will give you the screen size.
The specific models of the laptops usually have uniform sizes of the screens. So, if you know the model number, you can very easily look up its screen size.
The measurement of the width of a television screen can be done with a measuring tape. Typically, however, television screen measurements are done based on the length of the diagonal of the screen. To measure this, place the measuring tape at one corner of the screen and measure the distance to the opposite corner.
you would use a ruler to measure a computer screen.
you measure the computer screen diagonally, so if you have a 17" computer screen, and you measure it straight from side to side, then its not 17". You have to measure diagonally. I.e. Top left coner of the screen ( do not include the housing) to the bottom right side of the screen
foot
The same way you measure a TV screen, diagonally (any corner to opposite corner).
by measuring diagonal length
Most computer companies use inches to display their screen sides.
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
Yes, you measure the TV, or monitor screen (computer) diagonally. On the newer flat screens the measurement may be a tad off, but you can get the general idea.
Use A Tape Measure.
The main unit of measure on a computer is pixels. Most icons on a computer are 16x16 pixels by default.
You should not. You should use centimetres.
Measure diagonally with a tape measure from corner to corner of the viewable area only. Doesn't matter if you start on the top corner or the lower corner.
