So How to measure ?

1. Take a measuring tape or ruler (for small screens).

2. Hold the tape diagonally (from top left corner to bottom right corner) on the viewable area (the glowing screen only not the borders) of the monitor or LCD screen.

3. Now write down the accurate size in Inches or Cm (Centimetre).

Hope you got the right way now 😀
