Ask people which wall in their house needs art and almost nobody says the hallway. It is the wall they walk past ten times a day, see more often than any other, and have never once considered.
It is also, for a set of specific reasons, the easiest wall in a British house to get right.
Why hallways suit art
Three reasons, all peculiar to how these spaces work.
First, a hallway is passed through rather than sat in, which means a strong single image is a pleasure rather than a presence you have to live with. A bold piece that would dominate a sitting room is simply a moment in a corridor.
Second, hallways have almost no furniture, so there is nothing competing. Most living room walls are half obscured by a sofa, a television and a bookcase. A hallway wall is a clear surface, which is exactly what art wants.
Third, it is the first thing anyone sees, including you, ten times a day. A well chosen piece there does more work per pound than the same piece anywhere else in the house.

Viewing distance, and the one real constraint
British hallways are narrow, frequently under a metre and a half, which means you never step back from the art. You see it at close range and at an angle as you pass.
That changes what works. Fine detail is wasted, since nobody stops to study it. Strong composition, clear shape and definite colour are what read at a glance and from the side.
It also means very large pieces struggle, since you cannot get far enough back to take them in. A medium piece at close range beats a large one you can never see whole.
Height in a corridor
Slightly lower than the usual gallery convention. The standard advice puts the centre of a piece at 145 to 150cm, which assumes a viewer standing back and looking straight ahead.
In a hallway you are moving and your eyeline drops slightly. Around 140 to 145cm to the centre reads better, and it also keeps the piece clear of the light switches, coat hooks and radiator that occupy most British hallway walls at around a metre.
Working with the actual wall
Hallway walls are rarely clear runs. There is a radiator, a meter cupboard, a light switch, a staircase eating the top half, and a coat rack.
Rather than fighting that, use the sections it creates. The wall above a radiator is a natural frame for a horizontal piece, provided the artwork sits at least 30cm clear of the top so rising heat does not affect it. The stretch beside a door frame takes a narrow vertical piece. A stairwell wall suits a piece hung to the eye line of someone climbing rather than someone standing at the bottom.

Lighting a dark hallway
Most British hallways have no natural light at all, which is the main reason people avoid putting anything there.
The fix is a picture light or a small wall light placed to one side rather than a brighter ceiling bulb. A pool of warm light on a single piece transforms a dark corridor, where a brighter overhead simply makes it a bright corridor.
Our guide to lighting a piece properly covers the angle, and the same principles apply to flat art.
What survives a busy route
A practical consideration nobody mentions. Hallways carry bags, coats, hoovers, bicycles and children, and anything on the wall will eventually be knocked.
Canvas is more forgiving than glass here, since a knock dents rather than shatters. Hanging at a sensible height keeps pieces clear of shoulder level where bags swing. And two fixings rather than one keeps a piece level through the small daily impacts a hallway delivers.
Which pieces suit
Strong compositions rather than subtle ones. The blue half Buddha mandala and the gold half Buddha mandala at 60 by 80cm are portrait format, which suits a narrow wall better than a landscape piece, and the graphic quality reads at a glance.
The three heads in black works for the same reason: repetition reads instantly and the strong contrast survives poor light.
For a set rather than a single piece, four 30 by 30cm pieces hung in a row along a corridor gives you something at intervals rather than one thing you pass, which suits a longer hallway well.

The other hallway object
Worth saying since it follows the same logic. Hallways are the traditional placement for a laughing Buddha, facing into the home to greet what enters, and a console with a figure below a piece of wall art is a complete arrangement rather than two separate decisions.
Our guide to where a laughing Buddha should face covers that convention.
Questions people ask
Is a hallway a good place for art?
One of the best. It is passed through rather than sat in, has almost no competing furniture, and is seen more often than any other wall in the house.
What size art suits a narrow hallway?
Medium rather than large, since you can never step back far enough to take a big piece in. Portrait formats suit narrow walls better than landscape ones.
How high should hallway art hang?
Around 140 to 145cm to the centre, slightly lower than the usual gallery height, since you are moving rather than standing back. It also keeps pieces clear of switches and radiators.
How do I light a dark hallway?
A picture light or small wall light to one side of the piece rather than a brighter ceiling bulb. A pool of warm light on one object transforms a corridor; a brighter overhead just makes it brighter.
Will art get damaged in a busy hallway?
It will get knocked eventually. Canvas is more forgiving than glass, hanging above shoulder level keeps pieces clear of bags, and two fixings keeps things level.
