Sizing Lampshades for Your Floor Lamps

For you to size lampshades for your floor lamps, you have to size their respective heights and diameters.

Sizing Lampshade Height

You can size the height of a lampshade by measuring your floor lamp.Use tape or ruler to measure your floor lamp from the bottom of the base to where the socket attaches to the base. Then measure the widest part of your lamp base.

You can note down the numbers so that you do not forget them.The general rule is that the height of the lampshade should be between 0.25-0.4 of the height of your lamp base.Therefore, to get the right lampshade size for your floor lamp, multiply the height of your lamp base by 0.25 and 0.4.

If the base of the Tiffany arched floor lamp is 20 inches high, the lampshade should be between 5 and 8 inches.An inch variation in each direction still works if your preferred shade is outside the proposed range.

If you have to choose between shades of different sizes, always go for the larger one. A larger shade does not restrict you and can be modified to fit on lamps of different sizes.

It is best to use the side measurement instead of height if the top, side and bottom dimensions are provided for your prospective lampshade. The side and height dimensions are identical or fairly similar in different types of shades.

Sizing Lampshade Diameter

The diameter at the bottom is essential in refining your search for a lampshade of the right size.There are different ways to size the diameter of the lampshade for your floor lamp.

You can use the height of your floor lamp to calculate the correct diameter of your shade. This way, you can go for a shade within a two-inch range of the height of your lamp.For example, if the height of the Tiffany standing floor lamp is 8 inches, you can use a shade with a diameter between 6-10 inches.

Alternatively, you can use the width of your lamp to find the diameter of your preferred lampshade. You can do this by simply multiplying the width of the lamp by two.A Tiffany torchiere floor lamp that is 12 inches wide needs a shade measuring at least 24 inches wide.

Using your lamp’s diameter to size a lampshade is ideal for floor lamps. This is because such lamps can be taller, making it difficult to use the height to size the width of the shade.  Also, if the lampshade is tapered, its diameter should not be more than your floor lamp’s height.

Lampshade Fitting

Other than the size of the shade, you also need to know the type of fitter your floor lamp uses.A fitter is a component that attaches the lampshade to your floor lamp.Here are the different types of lamp fitters.

  • Clip-on. As the name suggests, it clips onto the bulb of your lamp without extra hardware. They are either large or small in size. The large fitters are the ones you can use for floor lamps.
  • Spider fitters. This is the common type of fitter used for floor lampshades.
  • UNO fitters. It attaches directly to the socket and does not need a harp. In most cases, it’s built into lamp designs.

The type of fitter for your lamp can affect the sizing of the lampshades for your floor lamp. Therefore, it is best to consider the type of fitters on your lamp while measuring the diameter and height of the desired shade.

Lampshade fitters are not ecumenical and as a result, there is need to check the base of your lamp and existing shades to determine the style of fitter for the lampshade.
