What it helps you decide
Choose a starting wick test band from vessel and wax inputs.
Candle testing
Choose a wick testing range from vessel and wax inputs.
Generate a practical starting band for common wick series, plus a reminder when a multi-wick test is more appropriate.

Your numbers
Vessel and wax
Use the filled example first. Then replace each field with a measured value or your best current estimate.
Step 1Answer one question at a time. Your example values stay available.
Important limit
Every candle requires controlled burn testing.
Full burn testing is mandatory. Vessel geometry, wick supplier, wax lot, fragrance chemistry, dye, cure time, room conditions, and safety standards can change performance. Test the final formula and container through the full burn cycle.

How to use the Wick Sizing & Vessel Guide
Choose a starting wick test band from vessel and wax inputs. The calculator runs privately in your browser and is designed to make the assumptions behind the answer visible.
What to have ready
Measure the real mold, vessel, fabric, or batch; then use the exact supplier ratio, density, usage ceiling, cure instructions, and expected waste.
Key inputs: Inside vessel diameter; Wax family; Fragrance load; Wax melt point; Dye / additive load.
How to use the result
Use the estimate to prepare a controlled test quantity. Confirm fit, cure, burn, color, strength, or cut yield before committing a full production run.
