How to measure a rectangle lamp shade:
Top (width x length): The top dimension has both a width and a length.
Bottom (width x length): The two bottom dimensions are measured the same way as the top. 
Slant Height: The height of the shade is measured along the slant. Slant height on a rectangle is measured at the mid-points of the top and bottom rings along the LONGEST SIDE.
