It has been suggested that you add the length and width dimensions of the room together in order to determine the proper diameter of the fixture to be placed in that room. For example, if the dining room measures 12ft by 14ft, use a fixtures that is approximately 26 inches in diameter. If you don’t feel the fixture suites the table it would hang over, then use the table’s width as the chandelier’s diameter.

The bottom of the chandelier should not be any lower than 30” from the top of the table and no higher than 36” above the tabletop.

The bottom of the fixture should be at least 7 feet from the floor. Therefore, if you have a low ceiling, you may need to install either a semi-flush or ceiling mount fixture. However, if you have a tall ceiling, you may need a 2 to 3 tier chandelier.

If you are hanging a fixture that weights over 50 pounds. This would apply to a fixture being hung from the ceiling or the wall.

The proper height for wall sconce installation is 60” from the floor.

Multiply the length times the width of the room, and then multiply that number by 1.5. For example, if the room is 12 ft by 16ft we would multiply 12 X 16 to equal 192. Then multiply 192 X 1.5 and you get 288watts. IF you are using lighting in a high task area, multiply the square footage of the room by 2.5 to get the amount of wattage required instead of 1.5.
