Your warp worksheet

Enter finished dimensions, then the sett and picks measured on the loom. Shrinkage is the percentage lost from woven size. Take-up is extra yarn over a straight woven distance. Set them separately for warp and weft.

Loom waste is added once. Unwoven allowance is added per item, for fringe or spacing. Woven hems belong in the finished length. Estimates exclude any extra reserve you choose for joins, mistakes or sampling.

Keep learning

Editing a saved plan creates a new revision. Select a revision before recording a finished sample to preserve the original assumptions. Enter measured dimensions before and after finishing. Negative observed shrinkage means the sample grew.

Keep your records

Free includes the calculator, one active plan, unlimited archived plans and full export. Archive a plan to free the active slot. Create JSON backups in Settings; CSV is a readable worksheet and cannot be restored. Restore replaces this device’s records after confirmation. Make a backup before replacing them.

Permanent Pro

Pro adds multiple active plans, reusable presets and side-by-side comparisons. If checkout is interrupted, use Restore purchase. Do not start another purchase while one is pending. Use the Google Play account that purchased Pro.

Storage trouble

A save failure leaves the prior saved record intact and retains the editor for retry. Check free device storage and close other Loom Plan windows. Do not clear app data to fix a save problem.
