Candle Jar Sizes

Start with the planned usable wax fill, target burn format, wick layout, label area, lid, box and desired shelf presence. Review outside dimensions together with the internal diameter and actual usable volume.

A wider jar may require a different wick configuration from a tall narrow jar. Request the drawing and sample, then confirm fill weight, component fit and burn performance before production.

A jar’s stated capacity does not directly equal the finished candle’s wax weight. Capacity is a volume reference, while wax weight also depends on wax density, headspace, wick base, vessel geometry and the chosen fill line. Use the listed capacity to compare models, then weigh the actual wax formula in a physical sample. Product labels and costing should use the validated net fill of the finished candle.

We can provide the jar dimensions needed for wick development, but a final wick specification must be validated with the actual candle formula. Wick performance changes with inner diameter, wax type, fragrance load, dye, wick material and the intended burn profile.

Use the vessel dimensions to select starting wick candidates, then complete repeated burn testing before approving the finished candle.

Match the lid to the exact finished jar opening and rim, including any insert, sealing ring or internal structure used by the lid. Nominal diameter alone is not enough to confirm fit.

Approve the jar-and-lid combination on production-representative samples, check opening and closing feel, and then confirm the assembled height and fit inside the final retail and export packaging.
