CraftCRAFTNUMA
About us
Free tools and practical explanations for people who sew, knit, crochet, quilt and make things.
What CraftNuma offers
CraftNuma is an independent clothing and craft calculator and learning project for an international audience. Our launch collection contains ten browser-based calculators in five categories, with interfaces in English, Spanish, French, Arabic, Hindi and Urdu.
Free core tools
All core calculator functions are free forever. You do not need to register, sign in or pay to calculate.
How we explain results
Every calculator states its formula, example and limits. Conversions use international units. Planning tools use explicit geometric or proportional assumptions and do not replace a pattern’s instructions, a swatch or a fitting check.
Original learning content
Our English guides explain the decisions behind the numbers and link to related tools. Other-language article editions will be published only when complete and reviewed. The website’s language interfaces are not a claim that every guide has been translated.
How the project may earn money
Advertising, affiliate partnerships and sponsorships may help fund the project. Current ad spaces are inactive reservations. Future commercial content and affiliate relationships will be clearly disclosed, and the core calculators will remain free.
Corrections and partnerships
Tell us if a result, explanation or translation needs correction. Please include the tool or guide name and enough detail to reproduce the issue. Use our contact page for support, advertising, affiliate and sponsorship enquiries.
