1. How to determine the chandelier’s diameter
Measure spaces’ length and width in feet, sum them up and that will be approximate diameter for the chandelier in inches.
For example 16 feet (Room Length) + 8 feet (Room Width) = 24 feet; The chandelier should be about 24 inches for its diameter
2. How to determine the chandelier’s height
Measure the space’s floor to ceiling distance in feet, multiple by 2.5 will be the approximate height for the chandelier in inches. This rule mainly apply to pendant style chandelier while not necessarily apply to ceiling style chandelier.
For example 11 feet (Room Height), 11*2.5 = 27.5 The chandelier should be about 27.5 inches for its height
3. How to determine the appropriate height for hanging a chandelier
If you are hanging the chandelier on an open floor, chandelier’s bottom should at least be 7.5 feet away from the floor.
If you are hanging the chandelier above a dining table or kitchen island, chandelier’s bottom should be 30 to 36 inches away from the tabletop.
Dining Room & Kitchen island
If you are hanging the chandelier above your dining table or kitchen island, you can also decide the size of the chandeliers based on the size of your dining table or kitchen island. We generally recommend that the length or diameter of the chandelier should be between 1/2 and 3/4 of the length of the dining table or kitchen island.
For example, let's say that you have a dining table with 60 inches in length. The chandelier should be between 30 (60 x 1/2) to 45 (60 x 3/4) inches in diameter or length (Same here 1/2 to 3/4 of the kitchen island length)
Two-Story Foyer with Staircase
The general guideline is to use the second floor as a reference point. Hanging the chandelier slightly lower than or at the top of the staircase. This way, when you are at the top of the staircase, the top of the chandelier will be at your eye-level.
On the other hand, many designers advocate for independent placement just to make the chandelier the focal point or placing the chandelier about another architectural features. For example. if there is a large transparent window above the door, it should be centered in the window for best visual result from outside.
Long Hallways
For example, the hallway’s width is 8 feet. The chandelier’s diameter should be about 20 (8 x 2.5) inches
