HOW TO MEASURE A LAMPSHADE

Measure a lamp shade using a straight ruler or taught tape measure, measuring in inches. You will need four measurements:

 

Top Width x Bottom Width x Slant and lastly, the Drop

 

1) The width across the top: should be measured from the outside edge of the top rim, to the outside edge of the top rim on the opposite side. Make sure the ruler passes through the "center" of the shade to ensure you are reading the maximum distance between the two sides.

 

2) The width across the bottom: should be measured from the outside edge of the bottom rim, to the outside edge of the bottom rim on the opposite side. Ensure you measure "through" the center of the shade so that you are reading the maximum distance from edge to edge.

 

3) The slant: should be measured in a straight line regardless of whether the shade has straight, vertical, sloped or curved edges in profile. Measure from the outside edge of the top of the shade, to the outside edge of the bottom of the shade. It's okay for this to be diagonal when the top of the shade is smaller than the bottom. Do not measure the "vertical" height. Always measure the slant from the outside edge of the top rim to the outside of the bottom rim, even if the sides of the lampshade are actually vertical.

 

4) The drop: is the distance from the top rim of the shade, to where the shade attaches to the lamp. This drop may be more significant for a tall cylinder or drum shade.

 

5) Rectangular or oval shades: have an additional measurement when viewed from above or below, the depth from front to back.
