Lamp Shade Measurements

by Jim Hoyle
Lamp shades are measured: Top x Bottom x Side i.e. 7 x 20 x 12 which is 7" wide
top, 20" wide bottom, 12" side/slant/slope
Note that the last measurement is not the vertical height but rather the side,
slant or slope which is slightly different.
In the case of a drum (barrel or cylinder) style the side is the same as height
but we do not use vertical height in measuring lamp shades.

Oval and rectangle have 5 measurements: 2 top measurements, 2 bottom
measurements, 1 side measurement. i.e. 7/12 x 10/16 x 13
One final measurement is the DROP or RECESS, the source of great confusion
in selecting the correct size lampshade. I mention it last because we consider
it last. INITIALLY FORGET ABOUT IT until after you have selected the correct
size. KISS = Keep It Super Simple and your fitting will be
super simple. If you attempt to find a specific size and a particular
DROP/RECESS, you will likely fail. It is like buying a car to fit your tire
wheels and completely unnecessary. First, find the correct shade shape and size that you
need. We can tell you the correct size HARP or SHADE HOLDER PIPE required for
that shade. If yours is different, simply order the harp or shade holder pipe
along with your shade - simple.
