How to use this tool

  1. Enter mandrel diameter, wire diameter, and inside diameter springback in the displayed units.
  2. Calculate and use each labeled result for chainmail ring aspect ratio. Compare the result with a measured sample before committing materials.

Try this example

{
  "mandrel": 6,
  "wire": 1.2,
  "spring": 0.3
}

Accuracy and scope

Jewelry geometry only. Weave compatibility depends on ring closures and material; not a load-bearing rating.
