A lamp harp is a metal wire assembly that mounts below the lamp socket, supporting the lampshade, and is often secured with a finial. Harps typically have brass, nickel, bronze, or antique brass finishes, with some being crafted from solid cast brass. Lamp harps are essential for floor and table lamps, ensuring the stability and positioning of lampshades. 

Moreover, the harp height should be considered especially when replacing a lampshade. Harps vary in size from 4 - 15 inches and are available in half size, like shoes.

How to Choose the Right Size of A New Lamp Harp 

Now that you’ve seen the different types of lamp harps, it’s essential to understand how to choose the right one for your specific lamp and shade. Selecting the correct size and type ensures not only a perfect fit but also an improved aesthetic and functionality for your lamp. Follow this step-by-step guide to make sure you’re choosing the best harp for your needs!

Step 1. Measure the lampshade:

Start by holding the shade in place over the lamp base. Measure from the top of the shade down to the point where the bottom of the harp will sit. This provides a rough idea of the harp size you’ll need. This is the critical way to determine the correct harp size as well as the measurement of lamp size generally. For example, if the measurement is 7.5 inches, you would round it up to 8 inches.

Step 2. Harp size guidelines:

  • Use the Formula: Overall Height - Fitter Recess = Harp Size (Length).
  • Rounding: Harps are sized in increments of ½ inch. If your calculation results in a fraction less than ½ inch, round down to the nearest ½ inch.
  • Example Calculation: For a shade with an overall height of 8 inches and a fitter recess of 0.25 inches, the harp size would be 7.75 inches, which rounds down to 7.50 inches (or 7 ½ inches).

Step 3. Consider other factors:

Ensure that the harp’s attachment method is compatible with your lamp. Harps can be attached using either a saddle (standard) or a detachable finial. Moreover, attach the selected harp to your lamp and then place the lampshade on it. Adjust the harp’s position as necessary to achieve the desired height and overall balance of the shade.
