How accurate is the yarn estimate?

The estimate is based on average stitch density and typical crochet patterns for each project type. Actual usage varies with your tension, stitch pattern, and hook size. We recommend buying 10–15% extra as a buffer.

What yarn weight should I choose?

Match the weight to your pattern. Worsted (4) is the most common for blankets and hats. Fingering/sock (1) works for delicate shawls. Bulky (5–6) is great for fast, cozy projects. Check the yarn label for the weight number.

What is a standard skein size?

The calculator assumes 200 yards (183 m) per skein, which is a common medium-weight skein. Many worsted skeins are 180–220 yards; check the label on your specific yarn and adjust the skein count accordingly.

Does hook size affect the yardage?

Hook size affects gauge (stitch density). A larger hook produces looser, more open stitches and uses slightly less yarn per square inch, while a smaller hook uses more. The estimator applies a small correction factor based on common hook size ranges.

Can I use this for tunisian or tapestry crochet?

Tunisian crochet typically uses 10–20% more yarn than regular crochet due to denser fabric. Add that buffer to the estimate. Tapestry (colorwork) usage depends on color changes; estimate each color separately.
