Plan your warp. Learn from the cloth.

See the arithmetic

Set finished dimensions, sett, picks, shrinkage, take-up and loom waste. Review estimated warp and weft yarn with the calculation explained.

These are estimates from your inputs. Add your own reserve for sampling, joins and mistakes.

Keep the original plan

Edits create revisions. Finished samples stay linked to the revision they tested, so you can compare planned dimensions with your measured results.

Keep a useful free notebook

The calculator, one active plan, unlimited archives and full backups are free. Permanent Pro adds multiple active plans, reusable presets and side-by-side comparisons. No subscription, ads or app account.
