Just hang one.

Try blowing up two balloons to the same size as the globes, or cut them out of paper, and hang them on strings taped to the ceiling with painters tape. That allows you to stand back and see what you think. It looks like your diagram could work.

Hi Hannah! First of all, thanks for that drawing--helps me visualize the situation. We actually have recommendations for how to hang 2 chandeliers over a long table. The best way to do it is to imagine cutting the table in half and then centering each of the chandeliers over their half of the table. Your chandelier sizes will work, too, based on our sizing recommendations.

Let me know if you have any questions!
