We find that our candles fill a medium-size room nicely. For larger rooms or rooms with high ceilings we recommend our  16oz candles or 2 or more 12 oz. Smaller candles are better burned at a desk or in a small space such as a bathroom. Because we use natural soy wax, our candles will not have the same scent throw as paraffin candles. We like that our candles are not overwhelming, but rather can be used every day.
