Measuring for Oval and Rectangular lampshadesįor oval or rectangular shades, please note there will be two additional measurements, due to the fact that the shade is wider than it is front-to-back. 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.

Note: Do not measure the "vertical" height. It's okay for this to be diagonal when the top of the shade is smaller than the bottom. Measure from the outside edge of the top of the shade, to the outside edge of the bottom of the shade. The height, measured on a slant, should be measured in a straight line regardless of whether the shade has straight, vertical, sloped or curved edges in profile.Ensure you measure "through" the center of the shade so that you are reading the maximum distance from edge to edge. The width across the bottom, which should be measured from the outside edge of the bottom rim, to the outside edge of the bottom 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. The width across the top, which should be measured from the outside edge of the top rim, to the outside edge of the top rim on the opposite side.

Measure a lamp shade using a straight ruler or taught tape measure, measuring only in inches. Measuring a lampshade will help you to find the right size shade for your lamp.
