For a typical setup (8-foot viewing distance, 55" TV, 42" seated eye height):
Mount at 27.7 inches from floor
How This Calculator Works
Our 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.
The Formula
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.
Shows optimal 17.5° downward viewing angle from eye level to TV center
Scientific Basis
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.
- Reduces cervical spine stress compared to looking up at high-mounted TVs
- Maintains natural head position for extended viewing sessions
- Optimizes eye movement patterns for better visual tracking
- Accommodates various seating arrangements and viewer heights

Given Measurements:
- Viewing Distance: 8 feet (96 inches)
- TV Height: 32 inches (55" TV)
- Seated Eye Height: 42 inches
Calculation Steps:
- Calculate viewing angle offset: 96 × tan(17.5°) = 30.2 inches
- Add half TV height: 32 ÷ 2 = 16 inches
- Final height: 42 - 30.2 + 16 = 27.8 inches
Result: Mount the TV so its center is 27.8 inches from the floor
This places the TV at an optimal viewing angle for comfortable extended viewing.
