A TV is measured diagonally based on its screen size, so a 32" television means that the screen is roughly 32" when measured from the top left corner of the picture area to the bottom right corner. Do not include the plastic frame in the measurement, just the TV picture area. TV Armor has 13 sizes designed to fit TVs ranging from 19" to 65". For example, the TV Armor 50-52 model fits TVs ranging in size from 50" to 52". Choose the TV Armor size that covers your TV screen size.
