Measuring your TV screen is easy, but it is important that you are careful to record the correct measurements so your screen is made to the correct size.Know what to measure
You need to measure the height and width of your TV where your non glare screen will install.
As seen below, most flat panel TV's have a bezel around the edge that you do not want to measure. You just want to measure the flat glass area of your TV... the part that displays the picture. The green area in the TV below is the area you need to measure.
Measure the height and width
Carefull not to damage your TV, use a tape measure and measure inside the bezel from left to right. This is the width of your screen. Record your measurement to the nearest 1/16th of an inch.
Do the same from top to bottom to measure the height of the screen inside the bezel. Record your measurement to the nearest 1/16 of an inch.
We recommend double checking your measurements by starting over from scratch. Measure the width and the height again and record your findings. Then double check the numbers with what you found the first time. This will help keep you from making a simple error that could have been avoided.
Now, this part you don't have to do. But we have found people have a much
easier time installing their GlareStopper™ screen if they round down at least 1/16 of an inch in both directions. We actually recommend rounding down a full 1/8 of an inch both directions.
This will give you a small gap around the sides of the screen that will not hurt the aesthetics of your TV or your viewing experience. This gap will ease the installation in case you are just a little far to one side or the other at the end of your installation.
If you don't round down it will increase the chance you will need to trim your screen if it fits too snug. Trimming the screen isn't hard, but will be inconvenient.
