Though you make your choice of style too well, you might go wrong with the dimensions. A very useful tip to choose the right sized chandelier is - add the length and width of your foyer and the number you get should be the diameter of your entryway chandelier! Also, remember that the fixture should be fixed at least seven feet above your floor. As they play a major role in your home decoration, it is good to select them after much analysis.
When it comes to the amount of lighting, foyer always needs more amount of light as it is the front entrance. Also, see to that you do not provide too much of bright light. That may result in producing glare, right at the entrance, and this may annoy the guests when they step in. But if you have anything really attractive in your foyer or if you have a staircase there, then it is mandatory to use a bright foyer chandelier or spot lights. If you have beautiful pictures or paintings displayed on your walls, you can showcase them with gallery styled accent lights or track lights in your foyers. Accent lighting is always an added advantage for foyer decoration.
