A 23-foot open-plan living room is one of the most common floor plans in 2026, and the most common decorating problem inside it is the wall. A wall this long is the largest single surface in most homes, and a single piece of art that is too small looks like a postage stamp on a billboard. A wall this long is asking for either a single panoramic piece, a wide diptych, or a deliberate sequence. Most of the advice online treats a 23-foot wall like any other wall. The advice is wrong. The 23-foot wall needs its own shortlist.
This guide is for the people on r/DesignMyRoom who have a 23-foot open-concept living room with a brick fireplace, a bay window, and a spiral staircase, and who are trying to figure out what to put on the largest wall in the room. The shortlist below is for 2026, for warm mid-century modern, and for walls between 20 and 30 feet long.
Why the 23-foot wall is different from a 12-foot wall
Most of the wall art advice online is written for 8 to 12-foot walls, which is the size of a wall behind a standard sofa in a 1990s living room. A 23-foot open-plan wall is a different animal. The wall is not just longer, it is also competing with three or four focal points. In a typical 2026 open-plan living room, the wall has to coexist with a TV on the adjacent wall, a brick fireplace, a bay window, and a curved staircase. The wall is the supporting player, not the lead.
The mistake most people make on a 23-foot wall is to put a single 36-inch piece in the center of the wall and leave the rest blank. A 36-inch piece on a 23-foot wall is not a focal point. It is a small object on a large surface. The eye does not know where to land, and the wall reads as half-finished.
What actually works on a 23-foot wall
Three options work in 2026. The first is a single panoramic piece in the 70 to 90-inch range, hung slightly off-center to balance the TV on the adjacent wall. The second is a wide diptych in the 80 to 100-inch total range, which gives the wall a deliberate object without taking on the commitment of a single oversized piece. The third is a three-piece sequence with 6 to 12 inches between frames, which lets the wall breathe while still reading as a single composition.
Avoid stacking small frames in a grid. A grid of 9 to 12 small frames in a 23-foot wall reads as a gallery wall from a 2010s Pinterest board, not a 2026 living room. A grid works on a 10-foot wall, where the frames can sit at eye level. A grid on a 23-foot wall has to either be very large (which is hard to source) or very small (which is a postage stamp).
Size: how big to go on a 23-foot wall
For a 23-foot open-plan wall, the rule of thumb is that the art should be roughly 50 to 60 percent of the wall width. That works out to 138 to 166 inches in total, or 70 to 90 inches for a single piece, or 80 to 100 inches for a diptych. The piece should be hung so its center sits between 60 and 65 inches from the floor, which is standard eye level for a 6-foot adult.
Hang the art slightly off-center if the room has a TV on an adjacent wall. The center of the art should be 12 to 24 inches off the visual center of the wall, leaning away from the TV. The TV pulls focus on its own, and a centered art piece ends up competing with it.
Color: what works in a 2026 open-plan living room
Three palettes consistently work on a 23-foot wall. The first is muted teal and deep blue, which is the most common 2026 living room palette and works in both warm and cool MCM. The second is terracotta and rust, which is the higher-contrast warm option and works against a cream or sage sofa. The third is pale cream and warm white, which is the softest option and works in a wabi-sabi or Japandi room.
Avoid pure black and high-contrast black-and-white photography on a 23-foot wall. Black reads as a hole in the wall, not a piece of art. A 23-foot wall needs a piece with color in it, or the wall reads as a black rectangle on a beige wall.
Texture: why a hand-painted impasto piece works on a 23-foot wall
A hand-painted impasto oil painting in the 70 to 90-inch range is the difference between a wall that looks like a gallery and a wall that looks like a poster. The reason is simple. A flat printed canvas is a photograph of a painting wrapped around a frame. At 80 inches wide, the print reveals itself as flat. A hand-painted impasto has actual paint buildup on the surface. The ridges catch natural light from the bay window and the side light from the brick fireplace differently throughout the day. The wall feels like it has something on it, not just a color.
The price difference is real. A flat printed canvas in the 70 to 90-inch range runs 80 to 250 USD. A hand-painted impasto in the same size runs 174 to 234 USD at our studio for a 60 by 90 cm piece, scaling up to 500 to 1,500 USD at a gallery for a true 80-inch piece. The flat print is cheaper. The impasto is the one that still looks considered in five years.
Three pieces that work on a 23-foot open-plan wall
The first is the Clash of Forces panoramic wildlife oil painting. The piece is a horizontal pull, which is the right format for a 23-foot wall. The color story is deep teal and warm gold, which sits inside the warm MCM palette while the panoramic format pulls focus across the room. Hang it 6 to 8 inches above a low walnut sideboard, and the wall reads as a deliberate object.
The second is the Oceanic Whirl dynamic school of fish painting. This is the wider option for a 23-foot wall with a bay window. The horizontal pull of the school of fish gives the long wall a horizon line that the bay window is also asking for. The palette is muted teal and cream, which sits inside the 2026 open-plan palette. Hang it 12 inches off-center to balance the TV on the adjacent wall.
The third is the Aegean Tides large textured blue and white abstract. The piece is a soft blue and white abstract, which is the wabi-sabi option for a 23-foot wall with a curved staircase. The impasto surface catches the bay window light, and the piece reads as a quiet object against a walnut and brass warm MCM room. Hang it as part of a three-piece sequence with two smaller pieces on either side, and the wall reads as a deliberate composition.
What to do if you already bought a 36-inch piece for a 23-foot wall
Hang it in the bedroom or the office, where a smaller piece reads as a focal point. A 36-inch piece is not a focal point on a 23-foot wall. It is a placeholder. Move the small piece to a quiet wall and put a panoramic or diptych on the long wall where the wall is asking for a deliberate object.
If the budget is tight, a flat printed canvas at 70 inches can work as a stopgap, but plan to replace it within 12 to 18 months. The flat print will fade and the wall will start to read as flat. A hand-painted impasto holds its surface and its color for 20-plus years.

Large wall art behind the couch and 23-foot wall FAQ
How wide should art be behind a couch? Two-thirds to three-quarters of the couch width. A 2.4 m (8 ft) sofa gets a 1.6 to 1.8 m wide art piece, hung with the bottom of the frame 15 to 20 cm above the sofa back. A 2.8 m (9 ft) sofa gets a 1.9 to 2.1 m wide piece. A 3.2 m (10.5 ft) sectional gets a 2.1 to 2.4 m wide piece. The art should be wider than the sofa back, not narrower.
How do you fill a 23-foot wall? Three options, in order of preference. First, a single oversized piece, 1.8 to 2.4 m wide, with the bottom of the frame 30 to 50 cm above the floor (if the wall is empty) or 15 to 20 cm above the nearest furniture. Second, a diptych of two pieces, each 1.2 to 1.5 m wide, with 10 to 15 cm between them. Third, a gallery wall of 5 to 9 pieces, 40 to 60 cm each, hung 145 to 155 cm to center.
What is the formula for a 23-foot living room wall? Single piece width equals 0.6 to 0.8 times the wall width. For a 23-foot (7 m) wall, that is 4.2 to 5.6 m, but most rooms top out at 2.4 m wide art because of shipping and weight. So the realistic formula is a single 1.8 to 2.4 m wide piece (or a diptych totaling that width), hung centered, with the bottom 30 to 50 cm above the floor if the wall is empty.
What is the most popular art size for a 23-foot wall? 60 by 90 cm (24 by 36 in) is the most-shipped size in our collection for a 23-foot wall. 90 by 120 cm (36 by 48 in) is the most-shipped for the wall behind a 9 to 10 foot sofa. Panoramic 60 by 90 cm or 90 by 120 cm pieces, hung as a single piece or a diptych, are the highest-converting size for the long wall.
How do I pick art for a long wall with no furniture below? Same single-piece formula, but the bottom of the frame should be 30 to 50 cm above the floor, not above the furniture. The piece is the focal point of the wall, not the anchor of a furniture group. The REGATTA textured sailboat impasto is the most-shipped 23-foot wall piece.
