About Skein & Stitch
How this calculator works
This calculator estimates the yarn needed for a knitted or crocheted blanket. It uses blanket area, yarn weight, craft, and stitch density, then rounds the result up to whole skeins.
The calculation factors are planning assumptions, not certified consumption standards. Use a pattern’s yardage or a measured swatch to refine your estimate. The calculator and reference table use the same factors.
