How to build a gallery wall around a TV

Screen sizes are quoted as diagonals, which are useless for layout. For a 16:9 panel, the width is the diagonal multiplied by 0.87 and the height is the diagonal multiplied by 0.49. A 55 inch class panel is therefore about 48 by 27 inches, a 65 inch about 57 by 32, and a 75 inch about 65 by 37.

Those figures cover the panel itself. Measure the actual outside edges of your set including the bezel and any wall bracket that projects beyond it, and use that rectangle in the plan. If the mount plate is wider than the screen, the plate is the boundary, because a frame placed against the panel edge will foul it during installation.

Set the screen height from seated eye level on the sofa you actually use. Sit down, have someone measure from the floor to your eye, and place the screen centre at or slightly above that figure. This almost always puts the screen centre below the 57 to 60 inch convention, which is fine: the art defers to the screen, not the other way round.

The conflict is worth naming because it is the root of most bad TV walls. If you hang the screen high enough for the art to sit at a conventional height, you get a screen that is uncomfortable to watch. If you hang the screen correctly, the surrounding frames sit lower than they would elsewhere in the room, and that is the correct compromise.

The keep-clear zone is larger than the screen. Hold 4 to 6 inches around the panel edge so frames do not visually collide with it, and if the mount articulates, measure the arm at full extension and full swivel and record the widest footprint it sweeps. That swept rectangle, not the parked position, is the real obstacle.

Allow for the soundbar and the cables. A soundbar wants 2 to 3 inches of clear wall below the panel plus its own height, and any vertical cable route, whether a surface cover or an in-wall channel, becomes a strip you should treat as a no-drill zone until the wall has been checked. Verify what is behind the wall before drilling anywhere near it.

The cleanest solution is two matching columns, one each side. The width arithmetic is simple: column width, plus the gap to the panel, plus panel width, plus the gap, plus column width. With 8 inch wide frames, 4 inch gaps and a 57 inch panel, the total is 81 inches, and you still need clearance to the trim at both ends.

That is the trap with flanking columns: they need a wide wall. If the available width is under about 90 inches for a 65 inch panel, either drop to a single column of narrower frames each side, or abandon symmetry. Squeezing the gap below 4 inches makes the frames look stuck to the screen rather than arranged around it.

An asymmetric wrap runs frames across the top and down one side only, stepping away from the panel as it goes. It needs far less width than flanking columns and it suits a TV mounted off centre on its wall, which is common when a chimney breast or a door dictates the position.

The named failure mode is the falling corner: an L-shaped wrap that leaves the screen apparently sliding out of the open corner. Fix it by placing one piece below the wrap on the same vertical line as the far panel edge, which closes the shape visually without adding a full column. Check the bounding box centre afterwards, since a wrap pulls it sharply towards the occupied side.

A switched-off screen is a large dark rectangle, and the quickest way to integrate it is to repeat that value in the frames: black mouldings, dark mats, or high-contrast black and white prints. The screen then reads as the largest member of a family rather than an intruder.

The trade-off is that dark frames on a pale wall raise the contrast of the whole group, which makes the arrangement busier and every gap error more visible. On a light wall, a middle path works better: dark mats inside lighter frames, which echoes the screen without turning the wall into a chessboard.

Enter the panel and its swept mount footprint as a furniture obstacle, the outlet as an outlet zone, and the cable route as a no-drill zone. The fit check then reports any frame that crosses them as an error rather than leaving you to notice it on the wall. Lock those zones so they cannot be nudged while you experiment.

With the obstacles in place, constrained auto-fit will place the remaining frames in valid positions with the clearance you set, and tell you plainly when a piece cannot be placed at all. That is more useful than a layout that quietly overlaps the screen, and it is why a TV wall is worth planning numerically rather than by eye.
