Make estimates more reliable without false precision

A calculator can produce many decimal places from uncertain inputs. That does not make the yarn estimate equally precise. The most useful improvements usually come from measuring your sample and your actual loom waste.

Round at the right stage

Keep the calculation values unrounded while estimating. Round warp ends upward to a complete threading repeat. Then round each yarn or color upward to the package size you can buy. A meter conversion in the middle should not silently drop an end.

Check the biggest drivers

More pieces increase both woven warp and weft. A denser beat raises weft requirements. A wider body increases both end count and the distance each weft pick travels. Larger outside loom waste affects warp alone.

The main planner makes those relationships visible. The weft calculator also shows pick count, which helps expose a mistyped PPI or a length entered in the wrong unit.

Compare the result with experience

After weaving, record the actual finished measurements, yarn remaining, and any changes made during weaving. Keep the sample alongside the plan. Use the next estimate as a controlled adjustment from that evidence.

Gist’s planning guidance emphasizes sampling and loom-specific waste. WeaveCompass deliberately avoids presenting one fiber percentage as a guarantee for every yarn and structure.

Offline Studio lets you compare saved plans; the free planner can export each scenario as a JSON file. Neither changes the need to verify the physical cloth.
