Lighting Size & Installation Guide
Why Size Matters
A light isn’t just a bulb on a cord— it’s functional art that frames your room, sets the mood, and whispers volumes about your taste. Choose a fixture that’s too small and it disappears; too large and it overwhelms. Use the simple steps below to strike a gallery-worthy balance every time.
1. Find the Perfect Diameter
| Formula | Result |
|---|---|
| (Room Length in ft + Room Width in ft) → convert sum to inches |
Ideal fixture diameter |
Quick Example
12 ft × 14 ft room → 12 + 14 = 26 ft → ≈ 26 in diameter chandelier or pendant.
Designer Tip: When in doubt, go 1–2 inches larger for statement pieces—you’ll gain drama without visual clutter.
2. Nail the Fixture Height
- Measure ceiling height in feet.
- Multiply that number by 2.5-3 in.
10 ft ceiling → 10 × 2.5-3 = 25-30 in tall fixture.
3. Perfect Hanging Heights
| Where | Hang It Here |
|---|---|
| Dining table | 32–36 in above tabletop |
| Kitchen island | 32–36 in above counter |
| Entryway | Bottom of fixture 7 ft above floor |
| Living room (open ceiling) | Leave at least 7 ft clearance beneath |
4. Styling Multiple Pendants
For islands or long tables, each pendant should span ¼ the length of the surface, spaced evenly for clean symmetry.
5. Room-by-Room Cheat Sheet
| Room | Size Rule | Suggested Fixtures | Hanging / Spacing Notes |
|---|---|---|---|
| Living Room | Diameter formula | Chandeliers, pendants, flush mounts, floor lamps | Keep lowest point 7 ft from floor |
| Dining Room | ½–⅔ table width | Chandeliers, linear pendants | 32–36 in above table |
| Kitchen | ¼ island length per pendant | Pendants, recessed, under-cabinet | 32–36 in above counter |
| Bedroom | Diameter formula | Semi-flush, sconces, bedside lamps | Bedside light ≈ eye level when seated |
| Bathroom | Diameter formula | Vanity sconces, flush mounts | Sconces 65-70 in from floor |
| Entryway | Diameter formula | Chandeliers, flush mounts | Bottom at least 7 ft from floor |
| Home Office | Diameter formula (ambient) | Flush mounts; desk lamps for task | Task lighting aimed at work surface |
6. Detail Notes for Each Space
-
Living Room
- Focal chandeliers or pendants anchor seating areas.
- Layered lighting—table or floor lamps for reading nooks.
-
Dining Room
- Chandelier width: ½–⅔ table width.
- For long tables, two or three smaller pendants maintain balance.
-
Kitchen
- Island Pendants: rule of ¼ length per pendant.
- Under-cabinet LEDs banish shadows for prep work.
-
Bedroom
- Semi-flush ceiling lights for soft ambience.
- Bedside lamps: shade’s widest point should be twice the base width; height roughly equals nightstand height.
-
Bathroom
- Vanity sconces on each side of mirror—shadow-free elegance.
- Ceiling flush mounts keep humidity in check.
-
Entryway
- Statement chandelier greets guests; 7 ft clearance minimum.
- In long halls, space small ceiling lights every 8-10 ft.
7. Ceiling-Height Playbook
| Ceiling | Best Choice |
|---|---|
| Low (≤ 8 ft) | Flush or semi-flush mounts—maximum headroom, ample glow. |
| Standard (9-10 ft) | Chandeliers & pendants shine; keep bottoms ≥ 7 ft high. |
| High (≥ 10 ft) | Go bold with taller, dramatic pieces that draw the eye upward. |
Allow 2.5-3 in of fixture height for every foot of ceiling height to maintain proportion.
