Will it fit / 77-inch above a fireplace
15 of 19 77-inch models have published body sizes with and without the stand · checked 2026-10-26
Will a 77-inch TV fit above a fireplace?
Without its stand, a 77-inch TV here measures 67.4 to 70.18 in wide and 38.4 to 41.32 in tall, according to the makers' spec pages. A clear patch of wall at least 71 x 42 in above the mantel takes any of the 15; the narrowest, the LG OLED77C3AUA, needs 67.4 x 38.7 in.
Every 77-inch TV with a published body size
These are the dimensions "without stand" that each maker prints — the box that hangs on the wall. They are listed narrowest first. LG, Sony and Samsung publish a full width, height and depth for their 77-inch sets on the pages read for this site; the other 4 77-inch models listed on VESA Fit are left out here: LG OLED77T6PUA, Sony K77A60 have a pattern and weight on record but no body size, and LG OLED77M3YUA, LG OLED77W6PUA have a body size (on each model page) but no single with-stand size, so the fireplace and cabinet pages compare the same sets.

Width and height on the wall
The spread between the narrowest and widest 77-inch body is 2.78 in: the LG OLED77C3AUA at 67.4 in against the Samsung QN77S95HAFXZA at 70.18 in. A geometric 77-inch 16:9 picture is 67.1 x 37.8 in, and the bodies differ from it by their frames and by how each maker rounds its class size. If a chimney breast or built-in shelving limits the width, measure between the obstructions and compare with the width column, not with the screen size.
Height matters as much above a mantel, because the TV's bottom edge has to clear the shelf and anything that stands on it. The tallest 77-inch body here is 41.32 in and the shortest 38.4 in. Add the gap you want between mantel and TV to that figure to get the wall height you need below the ceiling or crown moulding. If the wall is shorter than about 38.4 in, a 75-inch set (bodies up to 38.5 in tall) is the next size down.
What 77 inches means over a mantel
A 75-inch set over a fireplace usually spans most of the chimney breast. At up to 41.32 in tall, it also takes a big share of the wall height: add the mantel's height and the gap above it, and on a standard ceiling the top edge can end up close to the cornice. Measure mantel to ceiling before choosing between this and a 75-inch set.
How far it stands off the wall
The thinnest body at this size is the LG OLED77G3PUA at 1 in deep; the thickest is the LG OLED77T4PUA at 10.3 in. On a wall mount the TV sits that far out plus the mount's own profile, which the mount maker prints on its box — a fixed or "low-profile" plate adds the least, a tilting or full-motion arm the most. Over a mantel, a tilting mount is the usual way to angle a high screen back toward the seats.
The LG OLED77T4PUA is not VESA compatible: LG lists no VESA pattern for this model (wallpaper, transparent or supplied-mount designs use LG's own bracket).
Weight on the chimney wall
Without the stand these sets weigh 50.5 to 132.9 lb, with a median of 71.2 lb; the heaviest is the LG OLED77T4PUA. A mount's rating has to cover the TV's weight, and a full-motion arm needs more margin than a fixed plate because the load sits further from the wall. Chimney breasts are often brick or stone; fix the mount with the masonry anchors its maker supplies for that wall, and keep drill holes away from the flue.
Neighbouring sizes
One size down, the 75-inch bodies here are 65.2–66.2 in wide (75-inch above a fireplace). One size up, the 83-inch bodies are 72.7–75.2 in wide and up to 44.19 in tall (83-inch above a fireplace). From a seat 10 ft 5 in away a 77-inch screen fills the SMPTE 30° view; mounting it high doesn't change that distance, but the screen's centre ends up above eye level, so measure from where you sit.
