Where a desk sits relative to a window determines light quality for the entire workday. It affects screen glare, eye strain over long sessions, and how you appear on video calls. It is the single most impactful desk placement decision in a room with a window. For the complete desk placement process — clearance rules, wall and corner configurations, and how to map the whole room — see the small home office layout guide.
The three positions
Desk position relative to window
| Position | What happens | Verdict |
|---|---|---|
| Desk perpendicular to window (light from side) | Natural light illuminates desk surface and face; no glare on screen | Best option |
| Desk facing window (window in front of screen) | Direct light hits the screen surface and causes glare; washes out display | Avoid if possible |
| Desk facing away from window (window behind screen) | You are backlit; screen is bright against a dark wall; can work with blinds | Works with management |
| Desk parallel to window but offset | Partial side lighting; some glare depending on window width and sun angle | Acceptable compromise |
Perpendicular placement: how to set it up
Perpendicular means the window is to your left or right when you are seated at the desk. The light enters at a 90-degree angle to your line of sight.
For right-handed people, a window to the left is slightly preferable — it illuminates the writing surface without the hand casting a shadow. For left-handed people, a window to the right is preferable for the same reason.
The key is that the window faces the side of the room, not the face of the monitor. Even if the angle is not perfectly 90 degrees — say, 60 to 75 degrees — the improvement over facing or backing the window is significant.
When the room layout prevents perpendicular placement
In many small rooms, there is only one window and one viable wall for the desk. If the window wall is the only option:
Window in front (desk faces window):
- Use window blinds or frosted film to diffuse direct sunlight
- Set monitor brightness higher to compete with ambient light
- A monitor hood can help in rooms with very intense direct sun
Window behind (desk faces into room, window behind):
- This is manageable with the right monitor and lighting
- Use a matte screen filter or ensure the monitor has low-glare coating
- The main problem is overcast-day visibility — on grey days, the room light behind the monitor is brighter than the screen. A desk lamp in front solves this
- See the reduce screen glare guide for specific adjustments
North, south, east, and west: does window orientation matter?
Window orientation affects light quality throughout the day more than total light quantity:
- North-facing windows (in the Northern Hemisphere): Consistent diffuse light all day; no direct sun; easiest to work with — any desk position works
- South-facing windows: Direct sun for most of the day; strongest glare risk, especially in summer; perpendicular placement most important
- East-facing windows: Direct morning sun; perpendicular placement or blinds needed before midday; afternoon light is indirect
- West-facing windows: Direct afternoon and evening sun; perpendicular placement important after midday; morning work is unaffected
Video call lighting and windows
For video calls, natural light from in front of the face is ideal. Perpendicular window placement (light from the side) is adequate. Window behind the face (backlighting) creates a silhouette — the camera exposes for the bright background, making your face dark.
If the only window position is behind the desk, add a small LED panel on the desk in front of you to fill in the backlight. This is the most common and cheapest fix for poor video call lighting.
Frequently asked questions
Should a desk face the window or face away from it?
Neither is ideal. Facing the window creates screen glare. Facing away from the window creates backlight. The best position is perpendicular — window to your side. If you must choose between facing toward or away, facing away is generally easier to manage: a desk lamp adds front light to compensate for the backlit situation.
Is it bad to have a window behind your desk?
A window behind the desk creates two issues: it backlights you on video calls (your face appears dark), and on overcast days it can be brighter than the screen, causing eye strain. Both are manageable — a desk lamp in front and blinds to diffuse the window light solve the practical problems. It is not ideal but is workable.
Should a desk face the wall or the room?
Facing the wall is the most common and practical choice for a home office desk. It reduces visual distraction while working, gives a clean backdrop for video calls, and makes wall-mounted storage above the desk accessible. The alternative — desk in the centre of the room facing in — takes more floor space and requires cable management from the floor.
Does the direction a window faces matter for a home office?
Yes, because it determines when and how intensely direct sunlight enters. North-facing windows give consistent indirect light — the easiest to manage. South-facing windows bring direct sun for most of the day — perpendicular placement or good blinds are important. East and west facing windows bring direct morning or afternoon sun respectively.
