Why Downlight Spacing Matters for Your Lighting Design
Proper downlight spacing is critical to avoid dark spots, glare, or an overly “spotty” ceiling. Whether you’re installing kitchen downlights, bathroom recessed lighting, or bedroom ambient lights, spacing impacts both aesthetics and functionality.
In this guide, you’ll learn:
- The golden rules for downlight spacing
- Room-specific layouts (kitchens vs. living rooms)
- How beam angles and ceiling heights affect spacing
- Common mistakes to avoid
The 3 Golden Rules of Downlight Spacing
- The “Divide by 2” Rule
For general ambient lighting:- Ceiling Height (ft) ÷ 2 = Spacing Between Downlights (ft)
Example: An 8-foot ceiling = lights spaced 4 feet apart.
- Ceiling Height (ft) ÷ 2 = Spacing Between Downlights (ft)
- Beam Angle Determines Spread
- Narrow beam (25°-40°): Accent lighting (artwork, shelves) – space closer.
- Wide beam (60°-120°): Ambient lighting – wider spacing.
Use our Downlight Beam Angle Guide to choose the right angle.
- Avoid Wall Glare
Keep downlights at least 2-3 feet away from walls to prevent harsh shadows.
Room-by-Room Downlight Spacing Guide
1. Kitchen Downlight Layout
- Task Areas (Countertops): Space 4-5 feet apart with 90° beam angles.
- Over Islands: Align 2-3 downlights centered above the island (30-40° beams).
- Low-Profile Downlights: Ideal for kitchens with low ceilings.
Pro Tip: Pair downlights with under-cabinet LED strips for layered lighting.
2. Living Room Recessed Lighting
- Ambient Lighting: Space 5-6 feet apart with 120° beam angles.
- Accent Walls/Art: Add adjustable downlights 2-3 feet from the wall (30° beams).
3. Bathroom Downlight Placement
- Shower/Tub Zones: Use waterproof downlights (IP65+) spaced 3-4 feet apart.
- Vanity Lighting: Avoid casting shadows on faces – install downlights 18-24 inches from the mirror.
Downlight Spacing Calculator (Cheat Sheet)
Ceiling Height | Beam Angle | Recommended Spacing |
---|---|---|
8 ft | 90° | 4 ft |
10 ft | 60° | 5 ft |
12 ft | 120° | 6 ft |
Common Downlight Spacing Mistakes
- Overlighting Small Rooms: Too many downlights create a “swiss cheese” ceiling.
- Ignoring Dimmable Options: Non-dimmable LED downlights limit flexibility.
- Forgetting Trim Styles: Baffle trims reduce glare, while open trims maximize brightness.
A: 4-6W LED downlights (2700K-3000K) create a cozy ambiance.
A: Yes! Combine recessed downlights with a statement pendant for layered lighting.
A: With 8-foot ceilings and 90° beams: 9 downlights (3 rows of 3, spaced 4 ft apart).
