Wick Sizing Guide
Wick sizing is one of the most important variables in candle performance.
Small changes in wick size can significantly affect:
- melt pool development
- fragrance throw
- flame stability
- burn consistency
- soot production
This guide is intended to provide a foundational framework for wick evaluation and testing.
Important Note
There is no universal wick size.
Wick performance depends on:
- vessel diameter
- wax type
- fragrance load
- dye usage
- environmental conditions
All wick recommendations should be validated through controlled testing.
General Starting Framework
Small Vessels
(2–2.5 inch diameter)
Typically require:
- smaller single-wick configurations
Medium Vessels
(2.5–3.5 inch diameter)
May require:
- larger single wicks
- or dual-wick configurations
Large Vessels
(3.5+ inch diameter)
Often require:
- multiple wick systems
- higher heat distribution
Testing Recommendations
When evaluating wick size:
- test multiple wick sizes
- document each burn cycle
- evaluate flame behavior over time
- observe melt pool consistency
Testing is more reliable than assumptions or generic charts.
Final Thought
The correct wick is not chosen by theory alone.
It is proven through testing.
