Outline the screen
Tape the full width and height to the wall. A diagonal number can hide how much visual space the television actually occupies.
Complimentary TV Planner
Choose the screen for the seat, not the showroom.
Use the distance from your main seat to the screen to find a practical size range, then check placement against your console and seated eye level.
Three checks matter more than the diagonal.
Protect comfortable sight lines
A screen mounted too high can create neck strain. Begin near seated eye level, then adjust for the real viewers and furniture.
Plan the whole wall
Leave room for speakers, cable access, ventilation, a correctly rated mount, and a console that does not force the screen too high.
