Hallway recessed lighting: one straight, honest row
Hallways are the simplest recessed layout in the house — a single centered row — and the easiest to get slightly wrong by stretching the spacing.
Quick answer
Run one row of downlights along the hallway’s centerline, spaced 5–7 feet apart: a 10-foot hall needs 2 fixtures, a 16-foot hall needs 3, and a 20-foot hall needs 3–4. Four-inch fixtures suit the narrow ceiling.

- Beam angle
- 60–90° — wide beams bridge the gaps
How many recessed lights for a hallway?
| Room size | Ceiling | Fixtures | Layout | Light level |
|---|---|---|---|---|
| 4′ × 10′ | 8′ | 2 fixtures | single row, ~5′ apart | ≈ 20 fc |
| 4′ × 16′ | 8′ | 3 fixtures | single row, ~5′ apart | ≈ 19 fc |
| 5′ × 20′ | 9′ | 3 fixtures | single row, ~7′ apart | ≈ 12 fc |
Long halls tempt you to stretch the spacing; past 7 feet the ceiling reads as a row of spotlights with dark valleys between. Add the fourth fixture.

Anchor the ends, then divide the middle
Start half a spacing from each end wall (2–3 feet), then divide the remainder evenly. Fixtures should land near doorways where hands find switches and keys find locks. If the hall has art, this is the cheapest gallery you will ever build: shift the row 18 inches toward the picture wall or use small adjustable gimbals, and the corridor becomes a display.
In narrow halls, 4-inch fixtures keep the ceiling in scale — a row of 6-inch cans in a 3-foot-wide corridor looks like runway lighting.
The switching matters more than the wattage
Halls are pass-through rooms: three-way switches at both ends are non-negotiable, and a motion sensor or a low-level dimmer scene earns its keep every midnight. Warm 2700–3000K keeps the transition from bedroom to hall gentle.
How far apart should hallway recessed lights be?
Five to seven feet along a single centered row, starting 2–3 feet from each end wall. Under an 8-foot ceiling, closer to 5; under a 9–10 foot ceiling you can stretch toward 7.
Should hallway lights be 4-inch or 6-inch?
Four-inch is the usual pick — output requirements are low, and small apertures suit narrow ceilings. Use 6-inch only in wide halls (5 feet and up) or where you’re matching adjacent rooms.
Do stairway landings follow the same rule?
Treat each landing as its own small room with one centered fixture, and make sure the stair flight itself is lit from above without your body shadowing the treads — a fixture near the top of the flight does it.
