Light sizes to check before you buy
Designers start from three simple numbers.
- Add the room's length and width in feet. The total is a good chandelier diameter in inches. A 12 by 14 foot room suits a light about 26 inches across [1].
- Over a dining table, pick a light about 1/2 to 2/3 the table's width [1].
- Hang it 30 to 36 inches above the tabletop [1].
- Want the numbers for your room? Use the chandelier size calculator, or the pendant spacing calculator for a kitchen island.
Every picture is a preview made by AI at a believable size, not a measurement. How to check the size before you buy.
