Every flat I have lived in, I have moved the desk at least three times. The first arrangement is whatever the previous tenant did. The second is what a furniture shop suggested. The third — the one that finally stays — is always decided by two things nobody measures: what I actually do at the desk, and where the light falls at the hour I sit there.
The question "wall or window?" sounds like it has two answers. It has at least four, and the right one depends on the work.
Face the wall, and the wall becomes your whole world
The case for facing a wall is concentration. When the desk looks at a blank surface there is nothing to pull the eye, and for work that happens entirely on a screen — spreadsheets, code, email triage — that blankness is a kindness. Draughtsmen face their boards. Examiners face their desks. There is a reason.
But the wall you face for three hours a day is the most looked-at surface in your home, and most people give it no thought at all. If the desk faces the wall, the wall is not background — it is the room. A scuffed, socket-covered plasterboard at eye level will make the work feel temporary, in a way you will never consciously attribute to it.
So the first rule: if the desk faces the wall, the wall deserves one deliberate thing — a single framed print, a shelf with two objects, even just a coat of dark paint. One. A wall you face should be quieter than a wall you look at occasionally, but never dead.
Face the window, and you bring the street into the work
The case for facing the window is mood, and mood is real. Daylight on the desk, seasons visible, a sense of being in the world rather than sealed off from it. For work that involves thinking more than typing — reading, sketching, planning — a window-facing desk is the better room.
The cost is exactly the benefit: the window shows you everything. Movement pulls the eye involuntarily — that is biology, not weakness of character. And in the evening, a window facing you becomes a black mirror with your own face lit in it, which is a strange companion.
There is also the light problem, which people discover rather than foresee: a window directly ahead means glare on the screen for half the day and backlight for the other half.
The answer that usually wins: side-on
Place the desk so the window is to one side. This is the arrangement that survives.
You get daylight across the work surface rather than into your eyes. The view is there when you deliberately look up — which is the whole pleasure of a view — and gone when you look down. The screen faces inward, no glare, and in the evening the window is beside you rather than opposite.
One refinement, learned from years of drawing at a board: put the window on your non-dominant side. Right-handed, the light comes from the left; your writing hand does not cast a shadow across the page, and a lamp placed on the same side extends daylight into the evening without conflict. Left-handers mirror this, which is why the "correct" side of a room is not a fact about rooms but a fact about you.
The numbers that decide the rest
Placement is the first decision and dimensions are the second, and the second is where most home desks fail quietly.
Depth, 60–70cm. A 45cm desk is a writing desk from an era of pen and paper. A screen plus a keyboard plus a cup needs 60cm, and 70cm is comfortable. Below 60cm your forearms hang off the edge and your shoulders round forward within an hour.
Clearance behind, 80cm. You need 80cm between the desk edge and whatever is behind it to push the chair back and stand up without climbing over the chair. This is the measurement that makes a desk "not fit" in a room where it visibly does. If you cannot get 80cm, put the desk side-on to the wall rather than facing it and use the room's width instead of its length.
Screen top at eye level, 50–70cm away. The top edge of the monitor should sit at or just below your horizontal sight line, so your eyes rest slightly downward. On a laptop that means a stand — a £15 riser and a separate keyboard does more for your neck than any chair.
Never in front of a radiator. A radiator under a window is the classic desk position and the worst one: rising heat dries your hands and face, cooks the screen, and the window above gives you glare from one direction and draught from another. If the only wall is the radiator wall, put the desk beside it, not across it.
The corner is not wasted. An L-shaped arrangement in a corner gives you two work surfaces — screen on one leg, paper on the other — in less floor area than a single long desk, because the corner is floor you were not using anyway. The catch is the chair: a corner desk needs the corner cut at 45 degrees or you will sit with your knees against a right angle.
One more thing worth measuring before anything is bought: the distance from the desk to the nearest socket. A four-gang extension under the desk is fine; a cable across the floor to the far wall is the reason people stop using a desk they set up carefully.
And when there is no good answer
Some rooms offer one wall, one window, one radiator and no choices. Then stop solving it with furniture and solve it with light.
A mirror on the wall opposite the window will pull daylight halfway across the room — the oldest, cheapest and most underused piece of lighting equipment there is. A desk lamp with an opaque shade at head height turns a dead wall into an acceptable one. And if the corner is truly dark, the honest move is to accept it: a dark corner with a chair and a lamp is a reading corner, and the desk goes to the kitchen table instead.
The mistake is not putting the desk in the wrong place. The mistake is treating desk placement as a one-time decision — the room changes with the season, the work changes with the month, and a desk that cannot be moved is a desk that will be resented by February.
