Picking out a lampshade for a table lamp may seem simple, but there are actually a few guidelines to follow in order to find the right fit. While there are no hard and fast rules, understanding lampshade sizing and how to match the shade style to the lamp base will ensure your lighting looks balanced and cohesive.
Lampshade Size Matters
Contents
When considering lampshade size, both the width (diameter) and height are key measurements. As a general guideline:
- The width of the lampshade should be roughly equal to the visible height of the lamp base. So measure from the bottom of the base to the start of the light socket or bulb housing.
- The height of the lampshade will typically be around 2/3 the height of the visible lamp base.
- Make sure the shade is wider than the widest part of the lamp base itself, so it does not appear too small.
To put this into practice, if your lamp base measures 6 inches wide and the total visible height is 18 inches, you’ll want to look for a shade that is about 6 inches high and 12 inches wide. The width matches the width of the base, and the height is 2/3 of the total visible height.
When shopping for lampshades, you’ll see the dimensions listed for the top diameter, bottom diameter, slant (if applicable), and height. So match those measurements to the measurements of your lamp base for the best fit.
Measuring Your Existing Shade
If you already have a lampshade that you want to match the size and proportions of, it’s easy to measure it to find a suitable replacement. You’ll just need a tape measure to note the following dimensions:
- Top diameter (width)
- Bottom diameter (width)
- Slant or taper (if not straight)
- Overall height
With these dimensions in hand, you can then browse shades with the same or very similar proportions.
Choosing the Right Shade Shape
Beyond the size, the shape of your lampshade also matters when it comes to complementing the lamp base. Some guidelines:
- Square or rectangular shades pair best with straight, angular and geometric lamp bases.
- Rounded shades like empire, bell, and drum styles typically suit curved, spherical or sloping lamp base shapes.
- Oval and cylindrical drum shades are versatile options that can work well with squared or rounded bases.
- Column table lamps with long, vertical bases can potentially work with almost any shade style.
So match the shape and contour of the lampshade with the overall shape and lines of the lamp base for a cohesive look. An empire or oval shade on a square, modern lamp base would look a bit disjointed. But that same empire shade on a curved pedestal lamp base helps unify the look.
Lampshade Attachment Styles
When selecting a replacement lampshade, you’ll also need to make sure you get the proper lamp fitting or attachment. There are three main options:
Spider fitters: This is the most common type used for table and floor lamps. The metal arms (spider) attach the shade to a central harp, which then connects to the lamp socket.
Uno fitters: Uno shades attach directly to the lamp socket, so no harp is required. These integrated shades are common on smaller accent lamps.
Clip-on fitters: As the name implies, these shades have clips that attach directly to the bulb. Clip-ons are frequently used on chandeliers and sconce lights.
Check your existing lampshade to determine the type of attachment you need when buying a new shade. Spider fittings are by far the most prevalent, but make sure your new shade has the proper hardware.
Setting the Right Shade Height
Here are some additional tips for positioning your shade at the optimal height:
- For reading lamps, keep the shade below eye level to direct light downward and avoid glare.
- For accent lamps, a higher shade creates more ambient, diffused light vs. task lighting.
- Let the size of the lamp base itself visually guide the proportion for shade height. Taller bases suit taller shades.
You can adjust the shade height by moving the harp up or down on a spider fitting or adjusting chain links on clip-on styles. Find the ideal position for both aesthetics and ideal lighting.
When Rules Can Be Broken
While the above guidelines provide a great starting point for pairing lampshades with lamp bases, don’t be afraid to break the rules if you love how a shade looks on a base outside the recommended sizing and shapes. Trust your own eye for balance, color and style. If a tall drum shade on a short, geometric lamp gives you the perfect pop of color, go for it. There is no single “right” look. Experiment and have fun with different lampshades to reflect your personal taste and Transform a room.
Additional Tips for Picking Lampshades
- Select shade materials like linen, silk or cotton for softer, diffused lighting. Metallic and plastic shades direct light more sharply.
- Make sure the shade allows proper airflow and does not touch the light bulb.
- Consider an opaque shade to hide the bulb vs. a translucent style to allow some light through the shade material itself.
- Check that the shade width allows the base to still be visible so it does not appear hidden or engulfed.
- Mix and match shade styles on multi-light fixtures like dining room chandeliers.
- Layer multiple lampshades on a single base for eclectic flair.
- Complement your room colors and motifs with a printed or painted shade.
With these guidelines for properly measuring and selecting lampshades, you can confidently choose shades that enhance both the form and function of your table lamps.
Size absolutely matters, but so does finding just the right aesthetic for your unique style. Sources say there are no hard and fast rules when it comes to lampshades – if you love it, it’s the perfect shade for your lamp.
