OVER A TABLE The fixture’s diameter should be ½ to ⅔ of the width of the table.
Allow 30 to 34 inches between the surface of the table and the bottom of the fixture.

Allow 30 to 34 inches between the top of the island and the bottom of the light fixture.

The space between the pendants should be larger than the diameter of the pendant.

If you have a 2-story foyer, the bottom of your fixture should not be lower than the second floor.
Foyers with windows, be sure to center the chandelier within the window.

The bottom of the shade should be less than 60 to 65 inches from the floor.

Allow 75 to 80 inches between the surface of the floor and the bottom of the light fixture.

The bottom of the shade should not come as high as the eyeline of someone sitting on the bed. The shortest person to use the bed regularly would be a good bar to set for this measurement. Use the measurement to purchase the right lamp.

The bottom of the lamp shade should not be lower than the eye level of a seated person. It can be at or above eye level. If you're buying multiple floor lamps, try to keep them all within a close height range. This prevents each led standing lamp from looking awkwardly tall or short.
