Determine the correct diameter. Measure the length and width of the room in feet, and add those two numbers together. For example, if your room is 8 feet wide by 12 feet long, the sum is 20 feet. Change that number to inches and you will get a number that works for the diameter of your chandelier. In this case, a chandelier with a diameter of 20 inches would work well in an 8-foot by 12-foot room. For a dining room, the chandelier should have a diameter around 12 inches less than the table is wide. It's always better to have a chandelier that is slightly too big than too small.
Measure for the length. The taller the ceiling, the taller the chandelier can be. A foyer chandelier should hang about 7 feet off the floor, measuring from the bottom of the chandelier. For a chandelier suspended above a dining room table, there should be around 30 inches from the bottom of the chandelier to the tabletop for a dining room with an 8-foot ceiling.
Decide where to hang your chandelier. The location will affect the style of home lighting you choose. While most people think of chandeliers in dining rooms or a foyer, there are many other places you can hang a chandelier. Hang one with a dimmer switch over your bed in a master bedroom and turn it down to candlelight level for a romantic feel. Install a mini chandelier over a claw-foot tub in your bathroom for a touch of glamour. Consider installing mini chandeliers over a large kitchen island instead of standard pendant lights for a chic look.
Pick a style that matches the room. The chandelier should complement, not detract from, the theme of the room. A chandelier in a little girl's room, for example, could have colorful crystals dangling from it. A chandelier in a rustic dining room might be made with twigs or faux antlers. For a shabby chic room, try a chandelier with a distressed black or white finish and antique glass sconce shades. A recent trend in chandeliers is drums shades combined with crystals. A black drum chandelier with a cluster of dangling glass, for example, looks incredible in a modern dining room.
Adjust the height of the chandelier. Use pliers to remove links in the chain and coil up the extra electrical wire in the ceiling housing. If the chandelier does not have a chain, see if it has a sliding adjustment on the cord. Most chandeliers without chains have a sliding mechanism that allows you to double up the cord and shorten the length.
