When mounting a flat-screen TV on your wall, it is important to mount it at the proper height. What this proper height is ultimately depends on your preferences and the room's seating situation, but regardless of where you want to mount the TV, there is a way to ensure you measure the height properly. By measuring where you want the top of the TV to be located and subtracting the distance from the top of the TV to the wall mount, you can ensure your TV is mounted in the exact desired location.
Measure from the base of the wall up to the point on the wall where you want the top of the TV to rest. Write this measurement down. For example, if you want the top edge of the TV to be five feet from the base of the wall, the measurement would be 60 inches.
Measure from the top of the back of the TV to the point on the back of the TV where the wall mount attaches. Write this measurement down. For example, this measurement could be 15 inches.
Subtract the measurement you obtained in the previous step from the measurement you obtained in step 1 to obtain the height for your wall mount. For the example, the height of our wall mount would be 45 inches. This wall mount height would result in a TV whose top edge rested 60 inches up the wall.
