After struggling recently to find a couple of lampshade options for the cute little pair of milk glass lamps my mom had scored for me at a thrift sale, I decided to write a quick post to provide some guidance on size and shape for your next lampshade hunt.
1. Shape of the shade. When possible, the shape of a fabric shade should be similar to the base shape. You’ll also want to consider where the lamp will be placed. Will it be placed in a tight corner or grouped with other items where it’s likely to hit something?
Most lamp shades and bases generally fall into one of these shapes:
- Round – ball or cylinder
- Square
- Oval
- Rectanglular
- Hexagon
2. Shade bottom diameter. The best way to determine the bottom diameter of the shade for your table lamp is to measure the lamp height from the bottom edge of the table lamp base to the top of the lamp stem, (just below the socket cap).
The shade you choose for your lamp should have a bottom diameter that is within 2”, plus or minus, the measured height of your lamp. For example, if your lamp height (measured by the method noted above) is 14” tall, the shade you select (depending on your preference for a small, medium, or larger looking shade) should have a bottom diameter of 12”, 13”, 14”, 15” or 16”.
3. Selecting the shades overall height. The overall height of the shade is directly related to the height of the harp. As a general rule, the overall height of the shade should not exceed the the height of the harp plus 1/ 2”.
For example, if your harp is 7” tall, the shade you select should have an overall height in the range of 7 1/ 2” to 6 1/ 2”.
The shade height is important because you want adequate coverage of the bulb without covering the lamp base.
Note: Fringe and tassel should not be included in the measurement of the overall height of the shade.
Some table lamps, like my little milk glass duo, have multiple sockets or “clusters.” not a harp. In this case determining the proper height of a shade is similar to a lamp with a harp. The height of the shade should not exceed the the height of the cluster stem plus 1/ 2”, and should not be smaller than the height of the cluster stem minus 1/ 2”. To select the bottom diameter of the shade for your lamp, see step 2 above.
Because I like some of my lamps to have a small “wardrobe” of two shades, one for spring and summer and one for fall and winter, I selected a black linen bell shape for fall/winter and a burlap drum shade for spring/summer.
Feel free to drop back in and let me know what you scored for your lamps.
