TV Wall Covering: Molding Layouts Sized to Your TV
A TV wall covering works best when it is sized around the screen: a center frame or panel about 12 in (30 cm) wider and taller than the TV, side frames that split the rest of the wall evenly, and every molding line kept clear of the mount plate. Painted molding is the lowest-cost covering that still looks built in.
Most TV wall ideas are photo galleries: slats, marble, wallpaper, backlit shelves, with no dimensions anywhere. The problem shows up on installation day, when a frame rail lands exactly where the wall mount needs to sit flat on the drywall. You already know a plain wall behind a big black screen looks unfinished. This guide gives you TV sizes in inches and centimeters, the frame layout for 43 to 85 in screens on 12 and 14 ft walls, the mount height formula, and the clearance rule that keeps the mount flat. Our tv wall covering kit is the layout this guide starts from. The Square Edge Wall Molding arrives cut to size and ready to stick on.
Quick answer: Make the center frame the TV width plus 12 in: about 69 in (175 cm) for a 65 in TV. Split the remaining wall into equal side frames with 4 in gaps. Keep all molding outside the mount plate's footprint, plan in-wall cable plates inside the TV outline, and paint frames the wall color. Kits start at $210. A pre-cut option is the Shadow Box Molding Kit, Contemporary Accent Wall Panels, which installs with adhesive instead of nails.
Key takeaways
- A 16:9 TV is 0.87 x its diagonal wide and 0.49 x tall: a 65 in screen is 56.7 x 31.9 in (144 x 81 cm).
- Center frame = TV width + 12 in; on a 12 ft wall that leaves 29.7 in side frames for a 65 in TV and 21 in for an 85 in TV.
- A frame rail under the mount plate stops the mount sitting flat; keep molding at least 2 in outside the plate.
- KEF's formula puts a 65 in TV's center 60 in above the floor for a 36 in seated eye level.
- Painted molding costs $210 to $612 per wall in our kits, far below slat or stone cladding.
Which TV wall covering should you choose?
Choose by budget, room style and whether the wall must stay flat for a mount. Painted frame molding gives architecture for the least money and keeps the mount area flat. Wood slats add warmth and texture, wallpaper adds pattern, and stone or tile effects are the most expensive and heaviest.
| Covering | Look | Mount compatibility | Effort |
|---|---|---|---|
| Painted frame molding | Classic to modern, built in | Easy: plan frames around the plate | Low with a pre-cut kit |
| Board and batten grid | Bold, architectural | Plan a batten-free zone for the plate | Medium |
| Wood slat panels | Warm, textured | Mount needs spacers or a cut-out | Medium |
| Wallpaper or paint color | Pattern or color only | No issue | Low |
| Stone or tile effect | Heavy, high-end | Drilling through cladding | High |
Caveat: a very busy covering competes with the picture. Behind a screen you watch for hours, tone-on-tone molding or a deep paint color is easier on the eye than a strong pattern.
How big is your TV in inches and centimeters?
TV sizes are diagonal measurements, but layout needs width and height. For a standard 16:9 screen, width is about 0.87 times the diagonal and height about 0.49 times. Use the panel size here as a planning figure, then check your model's spec sheet, because bezels and stands vary by a fraction of an inch.
| TV size | Screen width | Screen height | Center frame (TV + 12 in) |
|---|---|---|---|
| 43 in | 37.5 in (95 cm) | 21.1 in (54 cm) | 49.5 in (126 cm) |
| 50 in | 43.6 in (111 cm) | 24.5 in (62 cm) | 55.6 in (141 cm) |
| 55 in | 47.9 in (122 cm) | 27.0 in (68 cm) | 59.9 in (152 cm) |
| 65 in | 56.7 in (144 cm) | 31.9 in (81 cm) | 68.7 in (175 cm) |
| 75 in | 65.4 in (166 cm) | 36.8 in (93 cm) | 77.4 in (197 cm) |
| 85 in | 74.1 in (188 cm) | 41.7 in (106 cm) | 86.1 in (219 cm) |
How to lay out molding around a TV: a worked example
Center the layout on the TV, make the middle frame 6 in (15 cm) wider than the screen on each side, and divide the rest into two equal side frames using the same gap everywhere. On a 12 ft (144 in) wall with a 65 in TV and 4 in gaps, that gives a 68.7 in center frame and two 29.7 in side frames. If you want trim that sticks on rather than nails on, see the Minimalist Wall Paneling.
- Screen width: 65 x 0.8716 = 56.7 in.
- Center frame: 56.7 + 12 = 68.7 in (174.5 cm), full height between the 4 in top and bottom margins.
- Space left: 144 - 68.7 - (4 x 4 in gaps and margins) = 59.3 in.
- Each side frame: 59.3 / 2 = 29.7 in (75.4 cm).
- Height: on an 8 ft wall with a 4 in baseboard, every frame is 92 - 8 = 84 in (213 cm) tall.
- Molding: 2 x (68.7 + 84) + 2 x 2 x (29.7 + 84) = 305.4 + 454.8 = 760 in, about 63 ft (19.3 m).
| TV size | Side frames on a 12 ft wall | Side frames on a 14 ft wall |
|---|---|---|
| 43 in | 39.3 in each | 51.3 in each |
| 55 in | 34.0 in each | 46.0 in each |
| 65 in | 29.7 in each | 41.7 in each |
| 75 in | 25.3 in each | 37.3 in each |
| 85 in | 21.0 in each | 33.0 in each |
If side frames fall under about 18 in, drop them and use one wide center frame with generous margins, or split each side into a stack of two frames above and below a shelf line.
How high should the TV go, and where must the molding stop?
Set the TV height first, then plan the molding around the mount plate. KEF's formula puts the screen center at seated eye level plus 0.22 times the viewing distance; for a 65 in TV viewed from 109 in with a 36 in eye level, that is 60 in from the floor. Keep every molding rail at least 2 in outside the mount plate.
The formula comes from KEF's TV height guide: viewing distance = screen size x 1.67, and center height = eye level + viewing distance x 0.22. Then:
- Mark the TV center on the wall at your chosen height.
- Outline the mount plate around it using the bracket's own dimensions, and find the studs it will screw into.
- Keep a molding-free zone: the plate must sit on flat drywall. A 13 or 20 mm frame rail under any corner of the plate tilts the TV.
- Plan cables: in-wall power and cable plates go inside the TV's outline, below the mount, so they are hidden and never fall on a rail.
- Check an articulating arm's swing: if the TV pulls out and turns, keep frame edges outside its swing so the screen does not hit the molding.
Good news for the center frame layout: with a frame 6 in wider than the screen, the rails sit well outside a typical mount plate, which is smaller than the screen. Problems come from grids and slats that cross behind the TV.
Pro tips
- Cut a cardboard template the exact size of your screen and tape it up with the molding layout. Live with it for a day; TV walls look different with the lights off.
- Paint the wall and frames a mid-to-dark tone. A dark wall makes the black screen disappear when it is off, which is the whole point of a TV wall.
- Install the mount and run cables before the molding, then fit the frames around it; never the other way round.
- Center the layout on the TV even if the TV is off center on the wall, then let the outer margins absorb the difference.
- Use a satin finish only if no window faces the wall; otherwise eggshell cuts glare off the frames.
- Leave a 1 in reveal between a floating media console and the bottom rail of the frames, so the console does not hide the lower line.
Common mistakes with TV wall coverings
- A rail under the mount plate. The TV tilts and the bracket stresses the drywall. Fix: molding-free zone around the plate.
- Frames sized to the wall, not the TV. The screen straddles two frames. Fix: center frame = TV width + 12 in.
- Cable plates on a frame line. Fix: plates inside the TV outline, planned before installation.
- Bright white contrast molding behind a big screen. It frames the black rectangle harshly. Fix: tone-on-tone or a darker shade.

Frequently asked questions
What can I put on the wall behind my TV?
Painted frame molding, board and batten, wood slats, wallpaper or a deep paint color all work. Molding is the lowest-cost way to make the wall look architectural while keeping a flat area for the mount.
Can you mount a TV over wall molding?
Mount it on the flat wall inside a frame, not on top of a molding rail. The plate needs flat drywall and stud fixings; plan the frames so the plate fits between rails.
How much does a TV accent wall cost?
With pre-cut molding, about $210 to $612 for the kit plus paint for one wall. Cladding in slats or stone effect usually costs more and takes longer to install.
How high should a TV be mounted on a feature wall?
Per KEF's formula, eye level plus 0.22 times viewing distance; for a 65 in TV at about 9 ft, roughly 60 in to the screen center. Lower is more comfortable for long viewing.
What color should a TV wall be?
Mid to dark tones such as charcoal, navy, deep green or taupe. They reduce glare and help the screen blend in when it is off; paint the molding the same color.
