Stitchulator’s calculators are based on standard quilting, knitting, crochet, sewing, and weaving formulas, checked against published sources. Their results are careful estimates, so where a result differs from your pattern or swatch, follow the pattern and swatch.

Calculator Results Are Estimates
Each calculator computes yardage, stitch counts, cutting sizes, or prices from your inputs, using formulas cited on its page. Real projects vary in ways no formula can measure:
- Gauge and tension differ between makers, so two people working with the same yarn can need 10% more or less of it and finish at different sizes.
- Fabric varies in usable width, shrinks when washed, and stretches on the bias.
- Patterns have their own seam allowances, ease, and construction choices; follow those over any general rule.
Measure, swatch, and check results against your pattern before cutting fabric or buying materials. Where we suggest buying a little extra, that margin is part of the advice.
Pricing Calculators
The pricing calculators total materials, time, and overhead into a price. They are planning tools, not business, tax, or legal advice. Prices that suit your market, and the taxes and licenses that apply to your sales, depend on where you live and sell.
Sources and Accuracy
Reference figures come from the organizations that publish craft standards, such as the Craft Yarn Council, and from yarn and fabric makers’ own published charts, and the sources are named on each page. Worked examples are checked against the calculator’s own output. If you find an error, please write to contact@stitchulator.com, and we will correct it.
Advertising
We show ads served by Google AdSense so we can offer the calculators free. Ads are chosen by Google, not by us, and an ad’s appearance is not a recommendation of the product. Calculator results are never influenced by advertisers.
