What Size of Lamp Harp Do You Need?
In order for the bottom of your lampshade to sit below your lamp’s light socket, you’ll need the right size of harp. Select a harp thats at least 1 inches shorter than the height of your lampshade.
If you would like a more dramatic look, with your lampshade covering a portion of your lamp’s base, choose a harp that’s 2-3 inches shorter than the height of your lampshade.
