If you’re hanging a chandelier over a table, make sure the bottom of the chandelier is 30” from the table surface. Adjust accordingly for taller family members. For higher ceilings you may increase that height to about 36” - 42” above the table.
Kichler Lighting Suggests:
Don’t worry, the formula is simple. Just add up the dimensions (in feet) of a room to arrive at the minimum diameter (in inches) for your chandelier. For example, if the dining room is 12’ x 14’, add 12 and 14 to equal 26. A 26” diameter should be the minimum size used in the room for maximum impact. If you are considering a linear chandelier, the length should be between 1/3 and 1/2 the length of the table. Now that you know the size, it’s time to figure out what shape is right for your space.
