How do I calculate the correct wattage to light a room?
Use some basic arithmetic. Room Length x Room Width x 1.5 = Proper Amount of Watts to Light a Room. For example, let’s take a 12x16-foot room: 12x16x1.5 = 288 watts of lighting. Therefore, a five-light chandelier using 60-watt bulbs will provide adequate light for the room.

For more concentrated lighting over a task or work area such as a kitchen island, simply multiply the dimensions of the island by 2.5.

How do I calculate the size and height for a chandelier in my foyer?
To determine the chandelier’s diameter, simply add the foyers dimensions together. For example, let’s say you have a 12x12-foot foyer: 12+12=24. Therefore, the foyer chandelier’s diameter should be approximately 24-inches in width.

The bottom of the chandelier should always be at least 7-feet from the floor. If there is a window above the front door, center the chandelier so it can be seen from outside. If the foyer is extra large, you may also want to include wall sconces for additional light.

What is the correct height for a chandelier over a table?
The bottom of the chandelier should be at least 2 1/2 feet above the table.

How much higher from the mattress top can the night table be?
Bedside tables should be 2-3 inches higher than the mattress - never lower. The surface should be large enough to hold a lamp, phone, alarm-clock/radio, glasses and reading material.

How tall should my night table lamp be?
When you are sitting in bed, the bottom of a table lamp's shade should be at eye level.
