Weaving Yardage Calculator

Free tools for rigid-heddle and floor-loom weavers: figure out how much warp and weft yarn a project needs, estimate a starting sett from a measured WPI, and look up a sourced reed/dent reference chart. No signup, nothing uploaded — everything runs in your browser.

Warp & weft yardage calculator

Project size, sett, PPI, take-up & loom waste → total yarn needed.

Sett (EPI) calculator

Measured wraps-per-inch → a starting sett estimate.

Yarn weight ↔ reed/dent reference chart

Sourced starting-point reed sizes by common yarn weight.

These are planning estimates from published weaving-education guidance (see each tool for sources) — always weave a test swatch before committing a full warp.
