Measuring lamp shades for table lamps Most table lamps take a shade with a bottom diameter of 16" or less, unless the table lamp is especially tall. "Mini" table lamps will need a much smaller shade. Measure the lamp's height from the bottom of the base to just below the bulb socket. Try to find a lampshade with a bottom width approximately equal to this measurement. A good height for lamp shades for table lamps is about 3/4 of the width of the shade, or 3/4 the height of the base up to the socket. You'll want to make sure that when the lampshade is positioned on the lamp, it will be tall enough to cover the top of the lamp fitter, and also hide the hardware, socket and part of the neck of the lamp base. When you view the lamp from the side you shouldn't see the hardware parts. Measuring lamp shades for floor lamps Floor lamps take a shade with a bottom diameter of 13",14",16" or 18" or larger. Similar rules apply as for table lamp shades, where the shade needs to be tall enough to cover the hardware so that you don't see the lamp socket or fitter from the side. Floor lamps typically require a slightly larger shade than table lamps. Also due to the height of the lamp, they tend to look better with a drum or floor-style shade. A floor shade is almost a drum shade, except the sides are slightly slanted. This shape complements the proportions of the floor lamp. White Lamp Shades A white lamp shade similarly can give your lamp a look of elegance and sophistication especially allowing the lamp base to be featured if it is colorful or interesting. White shades are clean and purifying, and may reflect upon white elements in the room or act as a canvas for other colors you wish to feature.
