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.
About this free craft materials & fabrication tool
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.
Excel spreadsheet export
Download the Wick Sizing & Vessel Reference Workbook
Use the Wick Sizing & Vessel Guide in your browser, then export a branded .xlsx materials worksheet to save material measurements, supplier assumptions, and the quantity planned for the project.
This gives you a portable materials worksheet you can save with an order, production record, planning meeting, or pricing review. The workbook keeps the source link and date with the numbers, making it easier to understand where the result came from when you reopen or share it later.
Spreadsheet questions
Using this tool as an Excel workbook
Use the browser calculator for speed, then take the result into the spreadsheet workflow that fits your business.
Can I export the Wick Sizing & Vessel Guide to Excel?
Yes. Enter your information, review the live result, and select Export to Excel. Batch Scale creates a branded .xlsx workbook with your inputs and the result shown by the tool.
What is included in the Wick Sizing & Vessel Reference Workbook?
The workbook includes a Tool Result sheet, an Inputs sheet, the original calculator link, and the date generated. When a supported calculator has an Excel formula profile, its result cells remain connected to the editable input cells.
Can I use the spreadsheet in Google Sheets?
You can import the .xlsx workbook into Google Sheets. Because spreadsheet applications sometimes interpret formulas and formatting differently, confirm any important result after importing—especially before using it for pricing, safety, compliance, or production.
Is the Excel download free?
Yes. The calculator and workbook are free. The first Excel export on a device asks for your email and permission to receive occasional practical Batch Scale resources. Once captured, later tool exports on that device download directly.
