Chandelier Size Calculator: Find the perfect size for every shape table and room (with illustrations)

Choosing the perfect chandelier can be an overwhelming decision. There are lots of factors to consider. I’m going to help you take all of the guesswork out of the equation.

There are two different size measurements, one for chandeliers that will hang over a table and one for chandeliers in a room. Once you have your chandelier, there are more measurements to consider like how low should it hang from the ceiling?

This is a simple, straightforward answer to your all of your chandelier size questions. If you have specific questions about a chandelier you are considering purchasing, leave a comment with the details of your room size or table size.

Size Calculator: Chandelier Over A Table

The formula for a chandelier size over a table is:

Table width in inches – 12 = maximum chandelier width

This formula works if you have a square or circular table. For example, if you have a 42-inch square or circular table, you want a 30-inch wide chandelier. If your table is rectangular, you still use the same formula for the width of the table, but you might want to consider a chandelier that isn’t round but more rectangular.

Rectangular chandeliers – If your chandelier is rectangular, the chandelier should not be closer than 12 inches from the long ends of the table.

Size Calculator: Chandelier For A Room

Use this formula if you are looking for a chandelier for your bedroom, living room, entry or any room where there is no table.

Room width in feet + Room Length in Feet = maximum chandelier width in inches

To give you an example, a room that is 12 feet wide by 14 feet long should have a 26-inch chandelier. You can go larger, but if you size down the chandelier might look too small for the space.

Size Calculator: Chandelier Height Over A Table

The rule of thumb for chandelier height is:

30-36″ above the table

This formula should be adjusted for the height of your ceiling. You can read more about the ideal height for a chandelier and how to adjust it here.

Size Calcultor: Chandelier Height For A Room

The height of a chandelier in a living room, bedroom, entry or any other room depends on the height of the ceiling.

For 8 foot ceiling, hang chandelier with bottom 7 feet from the ground

If your ceilings are higher than eight feet, the chandelier shouldn’t be hung higher than eight feet. If you have a chandelier hanging in an open 2-story area, it should not hang below the first story.

  1. Wow – you make it so easy Andrea! I’ve got a couple chandeliers in boxes waiting to be hung, and now I know how to do it, and even where to put one of them that I couldn’t decide before! Thanks for the completely useful info and inspiration! Happy Sunday!

  2. Hi Andrea!

    Thank you for your easy formula. My livingroom is 15’ L x 21’ W. I know I shouldn’t get a chandelier less than 36” but how big should I go if I want the chandelier to be the focal design element in the room?

    1. Madelyn,

      I think I would focus on finding one that you love the look of first. Then you can narrow it down by size. You can go bigger, but not if the ones you love don’t come that large. I would also look at how high your ceilings are. You can definitely go bigger than 36″ if your ceilings are 10 feet high. Its hard to say exactly how big you can go, do you have one in mind? If so share a link to it. I hope this helps.

    Redoing our kitchen and having difficulty placing chandelier. the window is off center. we opened wall to LR and centered chandelier on dining area window. problem the table and chairs are too close to pantries which go into dining area. purchased 24” chandelier as table was 48” round. if we open table with 18” leaf it fills the space better. I could send pictures so you could visualize better.

    1. The chandelier should be in the center of the table even if that’s not the center of the window. I would love photo if you’re willing to share you can always email me at [email protected]. I don’t think 24″ is too large for 48 inch round table.

      Thanks for your question!
