Screen size influences TV mounting height because larger TVs require slightly higher placement to maintain a comfortable viewing angle. While the center of smaller screens aligns between forty two and forty eight inches, larger screens, like seventy inches or above, may be centered around forty eight inches or slightly higher. This balances the vertical field of view and ensures the entire screen fits comfortably within your natural gaze. Adjust height within a few inches depending on room layout and seating distance to maintain ergonomic viewing and reduce neck movement during extended watch times.
