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!
Calculate Your Warp & Weft Requirements
I hope this calculator is super helpful and helps you get started on your weaving project quickly and easily!
Until next time…
Happy Weaving!
Thank you so much for this tool! I’m a pre-weaver (waiting for loom to arrive) and was really lost trying to figure out how much yarn was needed for a project. I’ve watched dozens of your videos on UouTibe and they’re so helpful.
That’s great to hear Tammi, thank you! And congrats on the new loom, which one did you decide on? 😀
I bought 2 hardback notebooks to weave covers for. I will try this out since I know the definite dimensions needed. Thanks!
Great, I hope they turn out well 😊
