Square wall art: the quiet luxury

There’s something about a square. It doesn’t lean toward portrait or landscape – it simply rests, balanced and calm, and a little unexpected on a wall. In 39.4x39.4 in (100x100 cm) it becomes a statement with the restraint of a gallery piece. Here’s why the square feels so exclusive, which size to choose, and how to frame it so it looks its best.

Why the square feels so exclusive

Most art is a rectangle, which is exactly why a square stands out. Its equal sides give it a stillness that portrait and landscape formats don’t have – nothing pulls the eye up or sideways, and the motif just sits there, centered and confident. It’s the format of art books, gallery catalogs and record sleeves, and it carries some of that feeling with it.

In 39.4x39.4 in the effect grows. One large square above a sideboard or bed has the presence of an original painting, without the busyness of a gallery wall.

Where a square works

Above the bed. One 39.4x39.4 in square centered above a queen bed is calmer than a pair and bolder than a single rectangle.

Above a sideboard. A square echoes the low, long lines of the furniture without competing with them. A 27.6x27.6 in print above a 39–47 in sideboard is just right.

In a grid. Four 19.7x19.7 in prints in two rows, 2 in apart, read as one large square – graphic, ordered and very calm.

Mixed in. One square breaks up a row of portrait prints and makes the whole group look more curated. Four ideas, drawn to scale above the furniture they suit:

The statement

One 39.4x39.4 in square centered above a 63 in bed or sideboard. Calm, grand and impossible to miss.

The grid

Four 19.7x19.7 in prints with 2 in between them, about 41 in across – made for a 63–71 in sofa.

The pair

Two 27.6x27.6 in prints side by side, about 57 in wide, above a 79 in sofa or a king bed.

The mix

A 27.6x27.6 in square between two 15.7x19.7 in portraits – the square holds the center of the group.

Frame it like a gallery

Our square frames come in 19.7x19.7, 27.6x27.6 and 39.4x39.4 in and in 16 colors – classic oak, dark oak, black and white, and softer or bolder shades like teal, plum, mint and sky blue. Choose "Add frame" on the poster’s product page and you get both in the same order. In 39.4x39.4 in the frame is sold together with the poster: we mount it and deliver it ready to hang.

For the full gallery look, add a mat board. A 15.7x15.7 in poster fits a 19.7x19.7 in frame with a mat, and a 19.7x19.7 in poster fits a 27.6x27.6 in frame – the wide border gives the motif room to breathe. Square mat boards come in 11 colors, from white and black to red, blue and orange.

Poster or canvas?

Square canvas comes in 19.7x19.7, 27.6x27.6 and 39.4x39.4 in, printed on finely textured canvas and delivered ready to hang. Add a floating frame in oak, dark oak, black or white, and the small shadow gap around the edge gives it the depth of a gallery piece. Painterly motifs like Out of Vase Blooms I and Porthmeor Sunset are beautiful on canvas, while graphic prints and photography come into their own as framed posters.

Torn between two sizes?

Tape both squares on the wall and look at them from the sofa or the doorway. A square has no long side, so it can look smaller on the wall than the numbers suggest – if you’re in doubt, go for the larger one.

What sizes do square posters come in?

Our square posters come in 15.7x15.7, 19.7x19.7, 27.6x27.6 and 39.4x39.4 in (40x40 to 100x100 cm). Square canvas comes in 19.7x19.7, 27.6x27.6 and 39.4x39.4 in.

Which frame fits a square poster?

A square poster fits a square frame in the same size: 19.7x19.7 in a 19.7x19.7 in frame, and so on. There’s no 15.7x15.7 in frame – a 15.7x15.7 in poster goes in a 19.7x19.7 in frame with a mat board.

Can I buy a 39.4x39.4 in frame on its own?

No, the 39.4x39.4 in frame is only sold together with a poster in the same size. We mount the poster and deliver it ready to hang.

Is there a mat board for 39.4x39.4 in?

No. Square mat boards fit our 19.7x19.7 in frames (with a 15.7x15.7 in poster) and 27.6x27.6 in frames (with a 19.7x19.7 in poster).

What size square should I hang above a sofa?

Above a 79 in sofa, one 39.4x39.4 in square or two 27.6x27.6 in side by side. Above a smaller sofa, four 19.7x19.7 in in a grid look great.

Does square canvas come ready to hang?

Yes. Our canvas prints arrive ready to hang, and you can add a floating frame in oak, dark oak, black or white.
