You may need replacement lamp shades for all kinds of reasons. A fabric lamp shade may get dirty, stained or torn. You may want to change your color scheme and have a fairly neutral lamp base so that only the shade needs to be replaced. Or you may break fragile glass lamp shades and need replacements for these.
When looking for replacements there are a few things to watch out for.
1. Ensure the Shade Matches the Base
The shade of your lamp needs to be the right size for base so that they are in proportion. A tiny shade on a large lamp base looks ridiculous as does a huge lamp shade on a tiny base. Also make sure that the two are in keeping in terms of color and style. They don't need to be the exact same color but they should tone with each other. And, as for style, twin a modern lamp base with a contemporary shade, an art deco base with an art deco type shade and so on.
2. Make Sure it Has The Right Fitting
It's no good finding the perfect replacement in looks if it does not actually fit your lamp. If you're not sure take your lamp base with you when you go shopping or simply measure the fitting.
3. Your Lamp Shade Should Match the Room
As well as the shade matching the base the whole lamp need to be in keeping with the style of the room so that it enhances it rather than detracts from it. A traditional room will not suit an ultra-modern lamp and vice versa. Also the colors of the lamp need to tone in with the color scheme of the room.
4. Make Sure Your Lamp Will Cast the Right Kind of Light
If you need a lamp for reading, don't use a dark glass or fabric shade which will mask too much light. If you need to cast light upwards to provide more general lighting then choose a torchiere type shade rather than a classic one. Also check that the shade can take a powerful enough light bulb. Some of them are only made for the weakest bulbs.
