Your project will almost certainly have to be adjusted somewhat. **The following steps will explain the process I used on this project and will use the measurements that I used. And since I would need a heavy duty lag bolt eye to hang the chandelier, I couldn't use a standard light fixture ceiling shroud, so that would have to be made as well. This meant I would need about 65' of wire. This provided plenty of light for the room and would fill out the look of the piece. Considering the dimensions of the rooms and chandelier itself, I chose to use 12 bulbs, 6 per beam. This provided an easier installation and better weight capabilities than typical old work ceiling fan mounts. I settled on installing a beam between the rafters which the the chandelier and electrical box would be mounted to. Since each beam weighed 25-30 pounds, weight became a concern for using a standard ceiling fixture box which only support about 75 pounds if installed as "old work" (installed after the drywall has already been installed). If you want your chandelier to hang down farther, just make the chains longer. Which meant the chains needed to each be about 20" long. Our beams are about 8" tall so if we left a 12" gap between the beams and the ceiling, the lights could hang about 15" below the beams. If you have 8' ceilings, you could still use our dimensions for an over-the-table chandelier. We have 10' ceilings and figured we need about 7' of head clearance underneath leaving about 3' for the whole chandelier. With the chandelier itself hanging down from the ceiling and the lights hanging even further down, head clearance can easily become a real problem, especially on lower ceilings.
