A:
Monitors are measured by their screen size. To measure your monitor position one end of a measuring tape at the lower corner of the screen, then pull the measuring tape to the opposite, upper corner of the screen. This measurement is your screen size. Always measure the diagonal across the screen, as this is how manufacturers measure them.
If your monitor, screen only, measurers 18.5 inches on the diagonal then this privacy filter will meet your needs.
