The simple formula to find ideal TV mounting height is to measure your seated eye level, usually about forty two to forty eight inches from the floor, and align the TV screen’s center at that height. To do this, add your sofa seat height plus the typical eye-line range above the seat, which averages between twenty six and thirty six inches. For example, if your sofa seat is eighteen inches tall, adding thirty inches places the screen center at forty eight inches. This method prioritizes natural head posture and clear sightlines. Adjust slightly based on viewing distance and screen size for maximum comfort and minimal glare.
