Warp and Weft Calculator

Please enter the finished width and length desired, along with your estimates of how much your yarn will shrink, its weight and cost, and other measurements.

When you press "Calculate" you will be able to see the width at the reed, the length of your warp yarn you will use when winding your warp, and your total yarn cost.
