The Great Candle Jar Size Debate: Net Weight vs. Water Weight

When shopping for high-quality candles, you might have noticed that the sizes of candle jars can be a bit confusing.  Many candle makers often mislabel the sizes of their candles, creating confusion for customers. Instead of accurately stating the net weight of the wax, some manufacturers use the water weight capacity of the jar, which can be misleading.  For instance, a jar that can hold 16 oz of water might only contain 14 oz of candle wax, because water is heavier than candle wax.  Yet they still label it as 16 oz. This inconsistency can lead to misunderstandings about the actual amount of candle you’re purchasing.


Understanding Candle Jar Measurements


Net Weight of Candle Wax:

The net weight refers to the actual weight of the candle wax that fills the jar. This is often the most accurate representation of what you're getting in terms of candle material.  


Water Weight Capacity:

Some manufacturers use the water weight capacity to advertise their candles. This measurement refers to the total volume the jar can hold if it were filled with water. For example, a jar that can hold 16 oz of water might only be able to hold 14 oz of wax due to the differences in density and volume between water and wax.


Why the Difference?

The difference in measurements often comes down to marketing and industry standards. Using the water weight capacity can make the jar size seem larger, which might appeal to their customers. However, incorrect labeling can lead to confusion and disappointment if the customer is expecting a certain amount of wax. 


Which Measurement Should You Trust?

For transparency and to ensure you know exactly what you’re getting, it’s best to look for the net weight of the candle wax. This measurement tells you the exact amount of candle material you’re purchasing. At Mountain City Candles, we always specify the net weight of our candles right on the jar to provide clear and accurate information to our customers.

Common Questions About Candle Jar Sizes

Why does my 21 oz 3-wick candle jar only have 17 oz of wax?

The jar may hold 21 oz of water, but due to the density and volume differences, it only holds 17 oz of wax.


Is it better to use net weight or water weight for candles?

Using net weight is generally better for accuracy. It clearly indicates the amount of candle wax you’re getting.


How can I tell if a candle’s size is based on wax or water weight?

Check the product details. Reliable manufacturers will specify whether the size refers to the net weight of the wax or the jar’s water weight capacity.


Why is there no standard in candle jar measurements?

Since there’s no regulated standard for candle sizing, manufacturers use varied practices, which can lead to inconsistencies. Always look for the net weight of the candle wax to make informed choices.


Conclusion

Understanding candle jar sizes can be tricky, but knowing the difference between net weight and water weight can help you make better purchasing decisions. Always check for the net weight to ensure you’re getting the right amount of candle wax.
