Ergonomic TV Wall Mounting: Seated Eye-Level Coordinates & Viewing Angles
Mounting a flat-screen television at the correct height is critical to prevent cervical neck strain and visual fatigue. The Society of Motion Picture and Television Engineers (SMPTE) and THX standards mandate that the vertical center of the television screen should be positioned directly at your eye level when seated in your primary viewing position.
The Wall Bracket Height Formulas
Screen Center Height = Seated Eye Level (Typically 42 inches from floor on standard sofa)
Bottom of TV to Floor = Seated Eye Level - (TV Screen Height ÷ 2)
Common Screen Size Mounting Guidelines (Based on 42" Eye Level)
