I have decided to do 3 15" pendants on my 11ft island. I was planning on 2 oversized ones (22"), but with only 9 ft ceiling height, the big ones looked odd.I have googled various advice for spacing of pendants. This is what I came up with. Does my math seem correct? My pendants will be 30inches apart, leaving 13.5 inches on the ends. Center of pendant 1 will be at 21 inch mark, center of middle pendant at 66inch mark(center of island), and center of 3rd pendant would be at 111 inch mark.
