One of the easiest ways to dress up your space and update the style is by changing your chandelier. Before you run out the door in search of the perfect chandelier, make sure you know the dimensions of your space. An appropriately sized chandelier should serve as a beautifying focal point that fits seamlessly into your overall design scheme.
For a room without furniture: Add the length and width of your room in feet, and then convert that number to inches. For example, a room that is 12 feet by 14 feet (12 + 14 = 26) would require a chandelier this is approximately 26 inches wide.
For a room with furniture: If you already have a dining room table in the space, the width of your chandelier should be about a foot smaller than the width of your table. This will leave a 6-inch clearance from the outer edge of the chandelier to the table’s edge.
The bottom of your chandelier should rest at least 30-34 inches above the tabletop. Adjust according to personal preference, fixture style and ceiling height. It is okay to hang your chandelier a bit higher in dining rooms with cathedral ceilings.
Chandelier height should be about three inches for each foot of ceiling height, so for a room with a standard 8-foot ceiling (3 x 8 = 24), choose a chandelier with an approximate height of 24 inches.
