How to Use This Calculator
- Enter the maximum workpiece weight — the heaviest piece of metal you plan to forge.
- Select the work type: Light (jewelry/tongs), Medium (knives/tools), or Heavy (axes/tooling).
- Review Recommended Anvil Weight and Minimum Usable Weight to choose the right anvil size.
- The ideal 50:1 mass ratio for heavy work means heavier workpieces require a proportionally heavier anvil.
- Use the weight range bar chart to compare minimum, recommended, and ideal options side by side.
