The screen diagonal of the monitor or TV screen to calculate
- To calculate the screen size of your device, you only need the height and width of the image area. This allows you to measure easily with a scale or other measuring means. In doing so, you should use the unit of centimeter.
- Then you can calculate the "Pythagorean theorem" the diagonal. The mathematical formula is "a2 + b2 = c2". Where a and b are the width and length dimensions you previously measured.
- Your screen is, for example, 65 cm wide and 45 cm high, the formula is: "652 + 452 = c2" or "4225 + 2025 = c2". Now you need to count only the Numbers "4225", and "2025" and the root of it. The end result is 79.1 cm. If you are not in your head calculate, you can easy a Online Pythagoras calculator use.
- Since most of the screen sizes are given in inches and not in centimeters, you must convert the inches yet. Share the result by the number of 2.54. In our example, it would be so "79,1 / 2,54 = 31,12". The screen would have a diagonal screen size of 79.1 cm, or 31,12 inches.
- Any measurement errors can be compensated for in the end simply by the fact that you round the result.
