By accessing and using Crochet Calc (the "Site"), you agree to these Terms of Use. If you do not agree, please do not use the Site. These terms apply to all visitors and users of the Site.

2. Use of Calculators

Our calculators provide estimates based on the gauge measurements and project dimensions you enter. Calculator results are mathematical approximations intended to assist with project planning. They are not guarantees of exact yarn requirements or finished dimensions. Actual results may vary based on stitch pattern complexity, tension variations, yarn characteristics, blocking, and other factors. Always purchase extra yarn as recommended by our tools (typically 10-15% buffer).

3. Content Accuracy

We make every effort to ensure our guides, data tables, and articles are accurate and up-to-date. All content is researched against Craft Yarn Council standards and reviewed by experienced fiber artists (see our Editorial Standards). However, we cannot guarantee that all information is free from error. If you discover an inaccuracy, please contact us so we can investigate and correct it promptly.
