Recessed Lighting Guide: 5 Distances That Work: Smart recessed lighting distances for small spaces — 5 ideas from a decade of kitchen and apartment makeovers

I once installed recessed lights too close to a client's crown molding and spent an entire Saturday convincing them it wasn’t a UFO invasion — lesson learned: distance matters. Small mistakes like that taught me how big an impact proper recessed lighting placement has on a room's mood and function. Small spaces especially can be magical if you get the spacing right; they force you to be clever with light and layout.

1. Classic wall-wash — 12 to 18 inches from the wall

For a soft, even glow that highlights artwork and textures, I typically place cans 12 to 18 inches from the wall. This distance helps wash the vertical surface without creating harsh glare. Advantage: great depth and accent effect; downside: takes more fixtures for even coverage on very tall walls.

2. Task-focused kitchen lighting — 24 to 30 inches from the wall

Over counters and islands I aim for 24 to 30 inches from the wall line so the light hits work surfaces effectively. In one small galley kitchen I remodeled, this spacing reduced shadows dramatically and made food prep safer. Trade-off: you may need dimmers to avoid a clinical feel at night.

3. General ambient spacing — 4 to 6 feet between fixtures

For overall ambient light in living rooms, spacing fixtures 4 to 6 feet apart works well. I use closer spacing in low ceilings and wider spacing in rooms with higher ceilings. It’s a forgiving rule that balances brightness with fixture count and cost.

4. Accent for cabinets and shelves — 6 to 12 inches insets

When lighting inside or above cabinets, recess lights 6 to 12 inches from the cabinet face to create a clean highlight without spilling light onto the ceiling. I once used this trick to make a small built-in feel custom and luxe. Minor challenge: you’ll need careful aiming or baffles to prevent hotspots.

5. Hallways and narrow spaces — 3 to 4 feet from walls

In corridors I place fixtures about 3 to 4 feet from the wall to avoid tunnel vision and ensure even illumination along the pathway. This spacing keeps the hall bright and welcoming without cluttering the ceiling with too many lights.

If you want to quickly visualize different recessed layouts for your room, I often sketch and then test options with a room planner to get proportions right before cutting holes.

Tips 1:

Practical rules: use lower lumen bulbs for close spacing, add dimmers for flexibility, and always check insulation-contact ratings before installation. For a full floor-to-ceiling layout mockup I sometimes export to a free floor plan creator to confirm fixture placement in 3D.

FAQ

Q: How far from the wall should recessed lights be?

A: For a wall-wash effect, 12–18 inches is typical; for general ambient lighting focus on fixture spacing rather than wall distance. Exact placement depends on ceiling height and desired effect.

Q: What's the best spacing between recessed lights?

A: A good rule is 4–6 feet apart for ambient lighting, closer for low ceilings and task areas. Consider light output and beam angle when finalizing spacing.

Q: Can recessed lights be too close to the wall?

A: Yes — too close can create glare, uneven light, or visible hot spots. Stay at least 12 inches for wall-wash looks and use baffles or adjustable trims if needed.

Q: How do I calculate the number of recessed lights needed?

A: Use room square footage and desired lux level: divide total lumens required by lumens per fixture. For quick planning, designers often use the 4–6 feet spacing rule as a practical shortcut.

Q: Are there insulation concerns with recessed lights?

A: Definitely — use IC-rated fixtures in contact with insulation to avoid fire risk. Non-IC cans require clearance; always follow local electrical codes.

Q: What beam angle is best for recessed lighting?

A: Narrow beams (15–30°) suit accenting; wider beams (60°) work for ambient light. Choose based on whether you want focused or spread light.

Q: Can I use recessed lights in bathrooms?

A: Yes, but use fixtures rated for damp or wet locations near showers. Follow electrical safety guidelines and place lights to minimize shadows around mirrors.

Q: Where can I mock up recessed light plans in 3D?

A: I often use a 3D floor planner that lets me place fixtures and visualize shadows before installation; this reduces guesswork and prevents surprises.
