How To Measure Your Screen

It is critical that you measure your monitor screen correctly to ensure proper fit of your computer filter.

To determine filter size, measure diagonally from one corner to the opposite diagonal corner. Be sure to measure only the viewable screen area. Do not include the dimensions of the screen's frame or casing.
