Starting wick range
CD-12 to CD-14
When to use this calculator
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
- Suggestion comes from diameter bands (about 1.6 in, 2.2 in, 2.8 in, 3.3 in, 3.9 in).
- 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.
