Our larger diameter candle covers are available from 1.75" up to 4" diameter. The smaller of these are often used as a candle cover on odd sized sockets. Our larger options are designed for creating a more substantial look on your fixture. For example, for our 3" and 4" diameter candles picture a large fixture in an open space or hotel lobby. Of course these larger sizes can be used in a smaller space but this gives an idea of the look of these candles.
