About FiberTools
Made by a Maker, for Makers
FiberTools started because I was frustrated. I picked up fiber arts a couple of months ago and quickly realized that the tools and references scattered across the internet were either clunky, buried in ads, or locked behind a signup wall. I wanted something better—fast, accurate calculators that work the way crafters actually think.
So I built them myself.
What You’ll Find Here
FiberTools is a growing collection of free calculators and references for crochet, knitting, weaving, spinning, and embroidery:
- Yarn & fiber — yarn weight, yardage estimates, fiber content
- Gauge & sizing — gauge calculators, blanket sizing, hat sizing
- Needles & hooks — size converters, hook guides, needle comparisons
- Specialty crafts — weaving sett, spinning ratios, tapestry planning
- Stitch tools — stitch counters, increase/decrease calculators
New tools are added regularly, and I’m always looking for ideas on what to build next.
How I Build
- Accuracy first. Fiber arts math matters. I double-check every formula and test with real-world values.
- No gatekeeping. No signup walls, no premium tiers, no email harvesting. Open the page, use the tool.
- Mobile-ready. Most of us reach for our phone mid-project. Every tool works on any screen size.
- Privacy by design. All calculations happen in your browser. I don’t collect or store your project data.
