Okay...I've researched online and I'm still not sure about choosing a chandelier for our 2 story foyer. This is what it looks like now. The entry is 8 ft x 11ft and is 18ft tall. Obviously the chandelier is way too small, and for some strange reason, the builder installed it centered on the hallway rather than the room. The bottom of the windows is 12 feet up. What size chandelier should I look for (height and width) and how high should we hang it?
