Generally, the height of a lamp shade should be the same or slightly shorter than the height of the lamp body. The circumference of the shade bottom should be approximately 2-1/2 times the circumference of the widest part of the lamp body. The shade should be placed so it covers the socket when viewed at eye level.
Note: 2-Piece Harps make it easy to switch to larger or smaller Harps.
