TV mounting height calculator

How it works

The calculator places the screen’s center at your eye height when it can, and otherwise as low as the furniture underneath allows. It then works out the angle from your eyes to the center of the screen and compares it with THX’s 15° guideline.

• Eye height: 42 inches for a sofa (Samsung’s figure); recliners about 4 inches lower (the UNIC cinema handbook gives 2–6 inches); in bed, your mattress height plus about 30 inches, the ANSUR II median seated eye height; standing, about 62 inches.
• Under the TV: a console adds a 2-inch gap, or 4 inches above a soundbar (Sonos Arc Ultra’s minimum). A fireplace adds 4 inches above the mantel.
• The limit: 15° above your eye line (THX). Cinema designers allow up to 25° for the front row and cap the angle to the top of the picture at 45° (UNIC); ergonomic guidance for screens prefers slightly below eye level (ANSI/HFES 100).

Over a fireplace, the height is only half the question. TV makers’ operating limits are 104°F (Samsung, LG, Sony) or as low as 95°F (TCL, Hisense examples), so measure the wall temperature with the fire lit before mounting. See TV above a fireplace.
