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.
