Are you sure this will fit this dining room?

I'm seeing it hung in room with taller ceilings typically

There seem to be two sizes

Yes, I’m doing the smaller size. My ceiling is 9’ and the room is 17x14, so I think the size will work.

I want to do the black + polished brass version to bring out the gold leafing in my artwork. Just not sure if I should coordinate the sconces with the fixture, or with the polished nickel fixtures in the butler pantry area ?

Do they have a rectangular version?
