What it helps you decide
Estimate mold volume and split manufacturer-defined resin ratios.
Resin craft planning
Mix enough resin for the mold—at the manufacturer’s exact ratio.
Estimate volume for rectangular or round molds, add a practical waste allowance, and split Part A and Part B by weight.

Your numbers
Mold and mix ratio
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
Use the manufacturer’s ratio basis.
A 2:1 volume ratio is not automatically a 2:1 weight ratio. Confirm ratio basis, density, working time, maximum pour depth, temperature, PPE, ventilation, and cure instructions from the resin manufacturer.
About this free craft materials & fabrication tool
How to use the Epoxy Resin & Mold Volume Calculator
Estimate mold volume and split manufacturer-defined resin ratios. 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: Mold shape; Length or diameter; Width (rectangle only); Fill depth; Molds / pieces.
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 Epoxy Resin & Mold Volume Excel Spreadsheet
Use the Epoxy Resin & Mold Volume Calculator 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 Epoxy Resin & Mold Volume Calculator 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 Epoxy Resin & Mold Volume Excel Spreadsheet?
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.
