Disclaimer & Affiliate Disclosure

Estimates are estimates

Content on CraftCalc is provided for general informational and educational purposes only. Yarn estimates, stitch counts, resize calculations and yardage figures are planning approximations, not guarantees: gauge, tension, fibre, stitch pattern and construction all change real outcomes. Always knit a test swatch for anything where running short or oversizing matters, and buy a buffer ball. Reference charts (needle sizes, body measurements, yardage bands, size charts) quote the named published sources, which themselves describe their figures as guidelines — verify against your pattern and your body before cutting or casting on.

Affiliate disclosure

Some links on this site are affiliate links, marked as such. If you click one and make a purchase, we may receive a commission at no additional cost to you. This helps fund the site. We only link to product categories genuinely relevant to the page (tools a maker would plausibly want), never to specific yarn brands as "recommendations".

Advertising disclosure

This site displays third-party advertisements (e.g. Google AdSense). Ad content is not endorsed by us and ads are labeled or visually separated from editorial content.

Accuracy & sources

Every factual page carries a "Last verified" date for its source tables. Craft standards and size charts do change (the Craft Yarn Council's system gained new categories in recent years, pattern companies revise charts), so treat the date as the freshness boundary of the numbers and re-check primary sources for anything critical.
