Choosing the right size of the candelabra lamp for your living room is complicated. However, a small suspended light can easily get ignored if it's installed in a big space. And, if the lamp doesn't have a strong design to attract the attention of the guests. On the other hand, large girandoles can be too overwhelming in a small space. Thus, the right candelabra lamp is proportional to the height and width of the room. Moreover, it depends on the furniture size in the room where you wish to place the light. So, to measure the size of the candelabra lamp for foyers or living room, you need to measure the length and width of the room. Then you need to add those figures together. And the sum of those two numbers is the approximate diameter of this lamp in inches.
