Replacing a dated light fixture with a beautiful ceiling medallion and chandelier is a great way to improve the look of a room. Adding a dimmer switch is a perfect way to control the level of lighting when entertaining.

Chandelier Size

There are several methods of determining the proper size of a chandelier:

  • Room Size: The length and width of the room added together in feet should equal the diameter of the chandelier in inches. Example: a 12′ by 12′ room should have a 24″ diameter chandelier (12 + 12 = 24″).
  • Table Size: In a dining room, the diameter of a chandelier should be at least half the width of the table. Example: a 42″ wide table should have a 21″ minimum diameter chandelier (42″ ÷ 2 = 21″). Another method is to make the diameter of the chandelier no larger than the width of the table minus 12″. Example: a 42″ wide table should have a maximum 30″ diameter chandelier (42″ – 12″ = 30″).

Chandelier Height

The height of the chandelier is based on the ceiling height and location:

  • Entry Hall: The lowest point of a chandelier should be a minimum of 6½’ from the floor. If possible, or with higher ceilings, hang it 7′ from the floor.
  • Dining Table: The bottom of a chandelier should be at least 30″ above the dining table (59″-62″ from floor). For ceilings higher than 8′, add 3″ for each additional foot of ceiling height. Example: With a 10′ ceiling, the bottom of the chandelier should be approximately 36″ above the top of the table.

Hanging a Chandelier

  • Start by determining the height of the chandelier.
  • Next, cut the support chain to length, leaving the electrical wire about 6” longer.
  • Turn the power to the light off at the circuit breaker box and remove the old ceiling fixture.
  • Run the wires through the trim ring and ceiling medallion, then through the hollow threaded tube in the center of the ceiling box.
  • Attach the wires to the house wiring using wire nuts.
  • Push the medallion and trim ring up against the ceiling, screw on the lock nut, and attach the chain.

Installing a Dimmer Switch

  • Select a dimmer switch that has a rated capacity high enough to handle the combined wattage of all the bulbs in the chandelier added together.
  • Turn the power off to the fixture at the breaker.
  • Remove the cover and existing switch.
  • Attach the dimmer to the wires using wire nuts.
  • Fit the wires back in the box, and screw the switch to it.
  • Replace the cover and turn on the power.

CFLs and Dimmer Switches

Compact fluorescent light bulbs (CFL) can’t be used with a dimmer switch unless they specifically state that they are designed to work with a dimmer switch.

    Danny = THere is talk about the new CFL? light bullbs. How does one dispose of them when they are burned out. I hear that there is a very complicated procedure because they contain mercury. Thanks

    I did not know that you could not use CFL bulbs with a dimmer switch. After installing the switch I tried to use a CFL bulb, now the fixture makes a buzzing noise. What can I do to fix this. Is the problem in the fixture or the switch?

    Hi Stanley,
    I have updated the article above to include the information you were looking for about chandelier height.

    I have a dining room chandelier that was connected to a dimmer switch, but did not dim. I replaced the switch (talking to someone at Home Depot to make sure I did it correctly) but the lights still will not dim. There are only 6 lightbulbs, and it does not exceed the 600 watts for the switch. What could be the problem with this? The chandelier itself seems to have a power wire and a ground wire going up to the ceiling. Does the fixture itself make a difference?

    I recently purchased a 7-light (60-W ea) chandelier to replace an older one in my dining room. I started to review the manual when I found a statement that the chandelier should not be used on a dimming circuit. What’s the problem with a dimming circuit if I’m using incandescent bulbs and the dimmer is rated to handle that wattage?

    Hi Jim,
    I have a dimmer on the multibulb chandelier in my house, and it works fine. As long as you use incandescent bulbs (most CFLs aren’t dimmable), I don’t know of any reason you couldn’t put a dimmer on it, but I would contact the company that made the chandelier and ask them. If there is a reason, be sure to let us know what it was.

    I’m trying to install a chandelier. It has 2 unmarked wires and a ground. The box has 3 wires + grd. (Black, red, white) and green ground. If I put black on 1 wire and white on the other,and put the grounds together, where does the red go?

    Hi Ron,
    Is it a three way switch by chance, with another switch going to the same fixture on the other side of the room? If not, you should only need two wires.

    i have a 11′L x 43″W table and i saw a oval chandeliers 40″w x12″D ( its long and narrow)and my room is 20′ x 13′-6″. i was wondering if the fixture is not too small above my table? what should be the dimension of a chandelier if you want to have a modern look and go in the length?

    The chandelier that I saw, Hope by Luceplan, comes in two sizes, 43″w x 26″h or 28.2″ x 21.2″. My table is 8ft w x 4ft L and extends approximately 40 more inches when opened fully. The living room and dining room are opened to each other and measure 17’4″ x 32’5″. The ceiling is 9ft. The larger chandelier is so impressive but I dont know if it would be too large. Which one do you recommend and how high do I hang it?
