We're looking to replace the ceiling fan in our dining room with a chandelier, and I'm having some questions about sizing. The table is 75"x42" when it's at its normal size, but it does have two 18" extensions that are sometimes used, at which point it becomes a 111"x42" table. The room is 13'x17', and the ceilings are a little over 9' tall.

According to the various theories it should either be 21" in diameter (half the width of the table), or 21-31.5" (50-75% of the width of the table), or 30" (12" less than the width of the table), or 30" (length + width of the room), 26" (8" of table space should be left on either side of the chandelier). But none of these theories deal with having a dining room table with extensions.

So I've had a few thoughts:

1) one 26.5" round chandelier (which seems like the safest bet, but I don't know how good it will look when my table is fully extended or if the lighting will be sufficient)

2) one 30.5" round chandelier (which might suit the scale of the extended table, but might look too big for the regular size table)

3) one 40x24" linear chandelier (which would probably provide the best lighting for the extended table, but would this look weird with the regular table?)

4) two 18.5" round chandeliers (these chandeliers are a bit larger than they recommend for double chandeliers (I've read it should be 1/3 the width of the table, so 14" in my case) and I don't know if it would look weird with the regular table, but would probably do well for when the extensions are in. But then there's the issue of fixing the ceiling for where the old ceiling fan was, as there will be no fixture taking its place)

Which of these options do you think would work best with the space I've described, and why? Or do you think none of these would work, and suggest something else?

Many thanks in advance for your help!
