Starting wick range

CD-12 to CD-14

Vessel inside diameter maps to a starting cotton-wick range (CD-style sizes). This is a starting point, not a guaranteed burn.

You can still enter wick unit cost for the cost line on a candle.

How this calculator works

How we calculate this

  1. Suggestion comes from diameter bands (about 1.6 in, 2.2 in, 2.8 in, 3.3 in, 3.9 in).
  2. Wick cost is quantity × unit cost if you are costing a candle.

Example

Example: a 2.8 in jar

A 2.8 inch inside diameter lands in a CD-12 to CD-14 starting range for many soy jars. Fragrance and wax can move you off that range.

  • Always test burn.
  • Wide vessels often need two wicks rather than one huge wick.

How much should I charge?

Wick cost is usually small. The risk is a bad burn, which is a waste and reputation cost — test before you sell.

Pricing tips

  • Measure inside diameter at the wax line.
  • Keep notes: wax + FO % + wick + jar.

Common mistakes

  • Treating a chart as a substitute for a test burn.
  • Selling an untested fragrance load in a new vessel.
