🔧 How to Calculate the Ideal Chandelier Size

✅ Formula for Diameter

Room Length (ft) + Room Width (ft) = Recommended Diameter (inches)

Example:
For a 14’ x 12’ room → 14 + 12 = 26 → Ideal fixture diameter ≈ 26 inches

 

---

✅ Recommended Fixture Height

Ceiling Height (ft) × 2.5 to 3 = Fixture Height (inches)

Example:
A 10-ft ceiling → 10 × 2.5–3 = 25–30 inches fixture height
