1. Calculate the Right Diameter

Use this formula to find the ideal chandelier diameter based on the size of your room:

Diameter = Room Length + Room Width (in feet)

For example, a room that is 12 feet by 15 feet would give:

12 + 15 = 27 inches

This will be the recommended chandelier diameter. You may adjust slightly for style or proportion preferences.

2. Consider Ceiling Height

• Standard Ceiling (8 feet): The chandelier should be 20 to 24 inches in diameter.
• For Higher Ceilings (9-10 feet): Add 3 inches for every additional foot.
• For Very High Ceilings (Over 10 feet): Consider larger chandeliers (24 inches or more) or multi-tier options.

3. Ideal Chandelier Height

The height of the chandelier is important for visibility and elegance. Here’s the guideline:

• Dining / Living Rooms: Hang the chandelier 30 to 36 inches above the table.
• Entryways / Hallways: The chandelier should be at least 7 feet above the floor.
• If the ceiling is higher, add 3 inches for each additional foot of ceiling height.

4. Light Coverage

Ensure that your chandelier provides ample lighting for the room’s size. Consider wattage and the number of bulbs:

• Small Room (Up to 100 sq ft): 60-100 watts
• Medium Room (100-250 sq ft): 100-200 watts
• Large Room (250+ sq ft): 200-400 watts

5. Style and Placement

• Dining Table: Choose a chandelier with a width of 1/2 to 2/3 the width of the table.
• Living Rooms & Entryways: Choose a size that complements your space—neither too large nor too small.
