Height from floor to eyes when seated
Distance from seat to wall
Vertical height of TV screen
TV wall mount height calculator uses ergonomic principles and viewing angle optimization to determine the perfect mounting height for your television. The calculation considers your natural seated eye level and maintains an optimal viewing distance that reduces neck strain.
mount_height = eye_level - (viewing_distance × tan(17.5°)) + (tv_height ÷ 2)This formula ensures the TV center is positioned at an optimal 17.5-degree viewing angle below your horizontal line of sight, which is recommended by ergonomic studies for comfortable viewing.
Optimal 17.5° downward viewing angle from eye level to TV center
The 17.5-degree viewing angle is based on research from the Society of Motion Picture and Television Engineers (SMPTE) and ergonomic studies that show this angle minimizes neck strain while maintaining optimal visual comfort. This angle falls within the recommended range of 15-20 degrees below horizontal.
