The width across the bottom is what is referred to as the lampshade size. So a shade with the example measurements above would be referred to as a 16 shade.
The vertical height is approximately 1 less than the slant. The shade is normally 40% of the total height of the lamp, from the top of the slant to the bottom of the lamp.If you have an existing shade and want a similar one, simply measure it and find our shade with a similar measurement. If the measurements are not exactly the same as your shade, the height is the most important size to match with your existing shade. If you do not have an existing shade or simply want something different in style and/or size, measure from the top of the lamp's harp to just below the socket in which the bulb fits. Then match it to the height of a shade on our site. The item "Burlap Regular Hard Back Drum Lampshade" is in sale since Thursday, January 8, 2015.
