Blanche Field shades can be made in any size you can imagine and are usually sized to fit a particular lamp.
The subjective aspect of deciding on the appropriate size of the shade for a particular lamp cannot be reduced to guidelines or rules of thumb. Lamp bases vary so widely that any guideline for one would immediately be thrown out for the next. A good eye is the best determinant for general size as well as for shape.
- One general observation is that the bottom of the shade, when viewed horizontally, should be level with the bottom of the bulb socket in order to keep the shade from appearing as though it is draped over the lamp.
- If the vertical position of the shade needs adjustment up or down, there are a variety of spacers and harps that can adjust the height. These are available at most lighting stores.
