Crochet Scarf Calculator

Use this calculator to estimate the amount of yarn you’ll need for your new crochet scarf. Be sure to keep the same unit of measurement (ounces or grams) for both the swatch weight and skein weight.


Create a sample swatch with the same stitch, yarn and gauge that you plan on using for the final project.


This is the yarn you used for the swatch and will be using for the scarf.
