The next question I get asked is what size chandelier for above the dining room table.
This excerpt is taken from Currey & Company lighting:
A general guideline is to choose a chandelier that has a diameter equal to one-half the width of the table. The general appearance of the chandelier must be taken into account, too; that is, if it is a light airy piece it may be slightly larger than the standard.
Also the distance between the bottom of the chandelier and the top of the table should be 30"- 34" in a room with an 8' ceiling. Add 3 inches for each additional foot of ceiling height.
