With so many different shapes, sizes, and styles of light fixtures available, it’s easy to forget that they actually serve a real purpose; other than to look pretty of course. Recently, we have had a few customers ask us if the chandelier or pendant they are shopping for will be enough light for their room. And we tell them the simple method of how to find out.
It can seem like a daunting task to figure out how much light is needed in any room, but I assure you it is super easy and simple. All you need is basic math and the measurement of the length and width of the room in feet.
Calculate Wattage Needed for Any Room:
Sounds like it might be complicated, but it really is just simple math. To start all you need to do is multiply the length of the room in feet by the width of the room in feet. This will give you the square footage. For example, a 16 foot long by 14 foot wide room has a square footage of 224.
Once you have the square footage of the room, you can use it to find out how much wattage you will need for general lighting in the room. The reason the wattage calculation is important, is because most incandescent lighting fixtures have a maximum wattage listed. For example, a 6 light chandelier that uses incandescent bulbs might have a maximum wattage of 60 watts per light, for a total of 360 watts for the fixture. How would you know if 360 watts is enough for your two-story foyer light? Or is 360 watts overkill for the intimate breakfast nook?
To calculate the total wattage needed, multiply your square footage by 1.5. Going back to our example of the 16’ by 14’ room, which has a square footage of 224, we would multiply 224 by 1.5 and get 336 watts. The general lighting in the room will need to reach the 336 watts mark to ensure there is plenty of overall light.
