Foyer Tips Choosing a Light Fixture
A factor in determining whether to hang a flush mount, semi-flush mount, pendant or a chandelier is to make sure the bottom is at least 7 feet from the floor.
For multi-story foyers with a window above the front door consider centering the chandelier so it can be seen from outside.
If you have a foyer that is very large you may want to add wall sconces. Sconce should be installed about 60" off the floor and be 6 to 8 feet apart.
There really is not a set rule for the diameter of a foyer fixture. We like to see a visual balance without overwhelming the space while still providing a statement.
