Work out weaving warp length instantly with clear inputs, formula shown and shareable results.
Each warp end must cover the finished length plus take-up and shrinkage plus loom waste, and the total yarn is that length multiplied by the number of ends. Loom waste is a fixed length regardless of project size, which is why short warps are so inefficient and weavers batch several projects on one warp.
Warp length
per end = finished length x (1 + take-up) + loom waste
Total yarn
total = warp length x number of ends
per end = finished length x (1 + take-up) + loom waste. Each warp end must cover the finished length plus take-up and shrinkage plus loom waste, and the total yarn is that length multiplied by the number of ends.
Loom waste is a fixed length regardless of project size, which is why short warps are so inefficient and weavers batch several projects on one warp.
Enter number of warp ends, finished project length, loom waste, take-up and shrinkage allowance. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
