The short answer
Ask six questions in order: what the room is for, how big the art must be, which way up it should go, how its colors relate to the room, what you want to look at every day, and how the light falls. Scale and palette rule out most of the wrong choices, and the subject decides between the rest.
Choosing a painting for a room is easier when you stop looking for “the one” and start ruling things out. These six questions, asked in order, narrow thousands of possible pictures to a handful, and the last choice between them is simply the one you like best.
1. What is the room for?
Start with the mood you want. A bedroom asks for calm, a home office for focus, a dining room for conversation, a home gym for energy. Calm comes from soft palettes, wide horizons and still subjects; energy from strong color, diagonals and movement. A bustling street scene suits a hallway better than a bedroom, and a hushed moonlit river suits a bedroom better than a gym.
2. How big must it be?
Measure what the painting will hang above. Most designers size art at two thirds to three quarters of the furniture’s width: about 56 to 63 in over an 84 in sofa. On a bare wall, measure the stretch the picture belongs to, between a door and a window say, and use the same rule. The art size calculator does the arithmetic and lists the standard print sizes in range. Scale rules out more wrong choices than anything else: a painting can be perfect and still look wrong at half the size the wall needs.
3. Which way up?
The wall’s shape decides. Long, low spaces above sofas, beds and sideboards want landscape or panoramic pictures; narrow walls beside doors and windows want portrait shapes; a square niche wants a square. If you love a tall painting for a wide wall, hang it as one of a pair or a trio.
4. How should its colors relate to the room?
There are three honest relationships between a painting and its wall. It can echo the room’s main color, sharing its hue so wall and picture read as one calm surface. It can contrast with it, built around the color opposite on the color wheel, so it stands forward. Or it can sit neutral, soft and low in color, relating to neither. Echo is restful, contrast is lively, neutral is safe. The wall color matcher sorts the paintings into those three groups for any wall color you give it, and the guide to matching paintings to your wall color explains when to choose each.
5. What do you want to look at every day?
Subject matters more than people admit. Still lifes of fruit, bread and wine have hung near food for centuries; water, boats and skies suit a bathroom; flowers and gardens soften a bedroom; children, animals and bright color suit a nursery; movement, sport and wide open views suit a gym. Above all, choose something you will still want to see in a year. A painting you love in an imperfect spot beats a perfect fit you feel nothing for.
6. How does the light fall?
Light changes a painting more than any frame. Opposite a window, glass reflects the view, so choose matte or anti-reflective glazing, or an unglazed canvas print. Dark, low-key paintings, a candlelit interior or a night scene, need a lamp or a picture light, or they turn into a dark rectangle by evening. Pale, luminous works carry a dim corner on their own. Strong sun fades prints, so keep precious pieces out of direct light.
Putting the answers together
By the end you will have a size, a shape, a color relationship and a mood, which is enough to shrink a collection of thousands to a short list. Each room page already applies these rules to its own collection, with a mock-up drawn to scale:
Questions people ask
Should art match the sofa?
No. Matching the upholstery makes a room look like a showroom. Choose a painting that echoes the room's main color or contrasts with its accent color, and let the sofa be one of the things it relates to.
One big piece or several small ones?
One large piece is calmer and suits a focal wall, such as the space above a sofa, a bed or a mantel. Several small ones suit walls you walk past, such as hallways and stairs, hung as a group with 2 to 3 in between frames.
Does famous art look dated in a modern room?
Rarely. Old paintings have aged into soft, earthy palettes that sit well with today's neutrals, and a strong frame or a wide white mat makes even a Dutch still life look fresh. The contrast between an old picture and a new room is often the point.
