Measuring the Lampshade

1
Measure the top diameter with a ruler. Hold a ruler over the top of the lampshade, and measure from one side of the circle to the other. Use inches or centimeters depending what unit you’re most comfortable with.^{[1]

- Write the measurement down so you remember it.
2
Flip the lampshade over and measure the bottom diameter. Place the ruler over the bottom opening of the lampshade and measure it from one side to the other. Using inches or centimeters, record the measurement on paper for your reference.^{[2]

- If the lamp’s neck is exposed from under the lampshade, that means you need a longer lampshade.

Measure the side height of the lampshade. Flip the shade over so the top is facing up and measure the side of the shade with a ruler. The height is measured from top to bottom.^{[3]

- If the lamp is too tall for the shade, the harp will be exposed and cause a top-heavy effect.
- If your lamp is going to sit at eye level, it’s important to make sure the shade will be tall enough to cover the harp.
4
Measure the holder drop height. This is the distance from the top of the lampshade to the fitter. The fitter is the metal piece inside that holds the lampshade on the lamp. To measure the holder drop height, turn the lampshade upside down and hold the ruler from the top of the lampshade to the end of the holder drop.^{[5]

Choosing a Lampshade Fitting

1
Pair a spider fitting with a harp lamp. The harp attaches to the lamp base, and the spider fitting sits on top of the harp. You use a finial to screw the fitting on top of the harp. The shade sits on top of the removable metal harp of your lamp.^{[6]

Put an UNO fitting on smaller table lamps and swing arm wall lamps. An UNO fitting attaches directly to the lamp socket via an inner ring, which is held in place by the bulb. Installing one doesn’t require tools. All you need to do is screw in the bulb and attach the shade.^{[7]

- An UNO fitting is also recommended for bridge arm floor lamps.
- UNO fitters can be found on small and medium shades, and rarely on large and oversized shades.
3
Use a clip-on fitting for small accent lamps, nightlights, and chandeliers. This is a wire fitting that clips directly onto the lightbulb. There are different clip-on sizes, so make sure that the one you choose matches the size and shape of your lightbulb. Clip-on lampshades come in different sizes such as bell, conical, coolie, cylindrical, and drum shape.^{[8]

Choosing a Style

1
Select a lampshade to match the lamp’s base shape. As a general guideline, the lamp’s base should match the shape of the shade. If the lamp has a round base, you should use a round lampshade. Use a square shade on a lamp with an angular or square silhouette. However, there are exceptions to these rules.^{[9]

- For example, candlestick lamps have many curves and angles, so they can be paired with any lampshade.
- Pair a round shade with a square lamp that’s sitting on a round table.
2
Pick a lampshade that’s wider than the baseplate. Some lamps have flat, round baseplates, so a lampshade that’s wider than that will give the lamp a balanced look. With a wider lampshade, the lamp won’t look unbalanced. Vice versa, if the lampshade is decorative, choose a simple base^{[10]

Choose a smooth lampshade for a modern look. Smooth lampshades can be found as drum shapes and go with contemporary lamps. They go with simple shaped lamps. Box-shaped shades are also modern^{[11]

Pair pleated lampshades with antiques for a cozy vibe. Pleated shades go with Victorian era and other antique lamps. Bell shapes are also ideal for a Victorian-style lamp and antique décor.^{[13]
