Hi Sawyer, I agree with everyone above. I think 3 of your 13.5" pendents is a good amount to fit your island. I think you can space them at lease 30" apart. That will give you at lease 12.75" from the edge of the island. (for example: 12.75" space + 13.5" pendent + 30" space + 13.5" Pendent + 30" space + 13.5" pendent + 12.75" space = 126" Island). Good luck!
