I love the Gardner pendants by Hudson valley but cannot figure out the sizing. Our island is 6 feet long by 27 inches deep with 9ft ceilings. I was going to go with 2 pendants but they come in 3 different sizes. What size would you go with?

9 inch: height 23, width 9

11 inch height 28, width 11

13 inch height 31, width 13
