My kitchen island base is 8 feet long so I ordered 3 pendants that are 15.19 H x 10.5 W x 10.5 D. I then decided to extend the granite an additional 15 inches on one side of the island only to allow for wrap around seating. Total granite counter length will be 9"4 but base is still 8 feet. Do I hang the middle pendant over the center of the island or center of the granite? If I hang the middle pendant over center of granite, should I increase size of pendants? The next size up is 20 H x 13.75 W x 13.75 D. Base is installed but granite will not be for a few weeks. Cathedral ceiling if this makes any difference. Thank you.
