Sofa seat height directly influences TV mounting height because your seated eye level depends on it. Typically, sofa seat heights range from sixteen to twenty two inches. Add about twenty six to thirty six inches to the sofa seat height to estimate your eye level. For example, an eighteen-inch sofa seat plus thirty inches yields a forty eight-inch TV center height for ideal viewing. This ensures the TV aligns comfortably with your eyes without forcing neck strain. Adjust for personal preferences, furniture padding, and viewing distance to perfect the height relative to your seating setup.
