Planning your weaving projects just got easier! This free Warp & Weft Calculator takes the guesswork out of determining how much yarn you need for your rigid heddle loom. Simply enter your project dimensions, sett, and other simple weaving details, and the calculator will automatically determine your warp and weft yardage.
No more running out of yarn mid-project or buying too much—get precise calculations for warp length, weft requirements, and shrinkage allowance all in one place. Try it out below!
If you prefer the old school method of pen and paper, I have you covered for that too! Check out my free printable calculations sheet that also includes a mini class to walk you through filling out the calculations!
Please note, the calculator is not perfect, for example, the weft section at the bottom does overestimate slightly. Hopefully I can fine-tune that!
