Here's some advice from our guide to light sizing: If you are using a chandelier or ceiling pendant above a kitchen island or table, measure the width or diameter of your table. Then subtract 12" from that number. That's the maximum limit for the width or diameter of a hanging light. All 3 of your considerations fit into the diameter parameters! Yay! In that case, the decision comes down to more things like style, which one you just personally like best, etc. etc. Let me know if I can try to help you narrow it down any further.

Also make sure to hang the pendant at the correct height over your table. That info, and more, is at our light sizing guide: http://bit.ly/1cuh1Fj
