Get in Touch with CraftCalc Hub

CraftCalc Hub is built by crafters, for crafters. Whether you knit, crochet, bake sourdough, pour soy wax candles, or work with epoxy resin, our goal is to give you the most accurate, easy-to-use, and completely free calculators on the web.

We are a small independent project and your feedback genuinely shapes what we build next. If you have noticed a bug in any of our calculators, have a suggestion for improving an existing tool, or have an idea for a brand-new calculator that would help your craft, we genuinely want to hear about it.

Community requests we have already acted on include adding custom blanket sizes to the Yarn Yardage Calculator, supporting multiple wax types and fragrance densities in the Candle Wax Calculator, and adding a levain percentage breakdown to the Sourdough Hydration Calculator. Every suggestion from our community is read carefully and shapes the roadmap.

We typically respond to messages within one to three business days. For bug reports, please include your browser name and version, your operating system and device type, and a description of the steps required to reproduce the issue. The more detail you provide, the faster we can get a fix out to all users.

For partnership, sponsorship, or affiliate inquiries, please use the same form and briefly describe the nature of your request. We are always open to working with craft supply brands and maker-focused businesses that align with our crafter audience. We believe in transparent, authentic partnerships that provide real value to the people who use our tools every single day.
