Stitchulator is a free collection of calculators for quilting, knitting, crochet, sewing, and weaving: yardage, stitch counts, cutting sizes, and fair prices, answered before you cut or cast on.

What the Site Does
Makers keep asking the same questions: how much backing a quilt needs, how many stitches to cast on, how to space twelve decreases across a row, what to charge for a commission. We answer each one with a dedicated calculator, its formula, and a worked example you can check by hand.
- Quilting: fabric, backing, binding, borders, blocks, triangles, and precuts.
- Knitting and crochet: gauge, cast-on counts, even shaping, hats, socks, sweaters, and blankets.
- Yarn: yardage, weights, substitution, held-together strands, and weaving.
- Sewing: yardage, fit, gathers, pleats, zippers, cushions, and tablecloths.
- Pricing: fair prices for handmade quilts, knits, crochet, sewing, and embroidery.
How the Calculators Are Checked
We base every calculator on a published method: craft-standard bodies such as the Craft Yarn Council, yarn and fabric makers’ charts, and the established techniques quilters, knitters, and weavers already use, credited on the page. Worked examples are computed by the calculator itself and checked against the text, so the numbers you read match the calculator’s results. Pages are reviewed again whenever a formula or reference figure changes.
Your Numbers Are Never Sent
