Some images simply need more room than one poster can give. A towering wave, a lone swordsman against a burning sky, a car caught mid-drift under neon. Instead of hunting for a giant print that's awkward to carry and harder to hang, you can split the image across several posters. That's the idea behind triptych wall art and, more broadly, multi-panel wall sets.
What exactly is a wall set?
One artwork, divided across several posters. Hung side by side with 3 cm of wall between each panel, they rebuild the complete picture. Those narrow gaps don't interrupt the image; they give it rhythm, much like the gutters between manga panels or the folds of a Japanese screen.
The idea has deep roots. Painters centuries ago spread their grandest scenes over three hinged panels, which is where the word triptych comes from. The modern version keeps that power: from across the room you read one big image, and up close each panel almost stands on its own.
Layouts and their exact dimensions
With identical panels and 3 cm gaps, every configuration has fixed measurements. Here they are, so you know in advance what your wall can take.
Diptych (1×2): 63 × 50 cm
Two panels side by side. Compact enough for the wall above a single bed, a small chest of drawers or a desk. A football shirt split down the middle shows the effect nicely: one shirt, two halves in conversation.
Triptych (1×3): 96 × 50 cm
The classic. At 96 cm wide it's almost exactly two-thirds of a 140 cm bed, which makes it the natural choice above a double headboard. A samurai-at-dusk landscape, for example, unfolds across three portrait panels.
Frieze (1×4): 129 × 50 cm
Four panels for a banner effect. It suits 160 cm beds, sofas and long hallways. Picture a great wave in the spirit of Japanese woodblock prints rolling across that full width.
Horizontal panorama (1×3 landscape): 156 × 30 cm
Three panels turned sideways form a long, low strip. Ideal above a large sofa, a TV unit or a corner desk. A night-time drift scene, for example, makes the most of that cinematic, widescreen shape.
2×2 grid: 63 × 103 cm
Four panels in a tall block, higher than it is wide. Perfect for a narrow stretch of wall beside a wardrobe or a door. A retro arcade scene turns it into one glowing neon grid, like the front of an arcade.
3×3 grid: 96 × 156 cm
Nine panels, a feature wall in its own right. It needs a clear wall and decent ceiling height. Fill it with one big gig-poster image and the concert-hall feel is guaranteed.
Where wall sets work best
- Above the bed: a triptych or frieze anchors the bed visually and can stand in for a decorative headboard.
- In a gaming setup: behind the monitors, a horizontal panorama stretches the game out across the wall.
- In a living room or café: a 3×3 grid becomes the focal point, the spot everyone wants in their photos.
- Along a hallway: a 1×4 frieze follows your movement and reveals itself as you walk.
What to avoid: squeezing a set between two windows that sit too close together. It needs breathing room, at least 20 to 30 cm on each side.
Hanging with 3 cm gaps: the method
Even spacing is the whole trick. A panel that's off by a few millimetres breaks the flow of the image. Here's how to get it right.
- Lay everything on the floor first. Arrange the panels in order with 3 cm between them and check that the image lines up across every join.
- Mark a reference line. Using a spirit level, run a strip of masking tape horizontally where the top edges will sit.
- Find the centre. Measure the middle of the space and mark it. The central panel, or the central join for an even number, lines up with that mark.
- Cut a 3 cm spacer. A strip of stiff card exactly 3 cm wide, slipped between panels, keeps every gap identical.
- Hang from the centre outwards. For grids, work row by row, using the same spacer vertically.
A 3×3 grid is 156 cm tall. Centred at about 150 cm from the floor, it runs from roughly 72 cm up to 228 cm, so check your ceiling height and leave comfortable space above. For fixings that won't mark the wall, our guide to hanging posters without damaging walls compares every option.
Wall set or separate posters?
Go for a set when you want one powerful image, a clear focal point, something that feels like a single artwork. Choose separate posters if you like to swap things often, mix several worlds or arrange freely. The two also combine beautifully: a triptych in the middle, a standalone poster on either side. Our guide to planning a gallery wall covers that approach.
One image, a few centimetres of wall between the panels, and the whole room changes scale.
