YarnYield: Knitting Calculator

YarnYield helps knitters plan a project before the first stitch. Enter your gauge, finished size, and the weight of a swatch to see how much yarn you need, then spread increases or decreases evenly across a row or over several rows.

Yarn estimate
• Enter stitches and rows per 10 cm or 4 in, the finished width and height, and the weight of your gauge swatch
• See the yarn needed in meters or yards and in grams, plus how many skeins to buy
• Add an extra allowance and the number of pieces
• Get the cast-on count, with an optional stitch multiple for ribbing and lace, and the total number of rows

Even increases and decreases
• Spread increases or decreases across one row with step-by-step instructions that start and finish symmetrically
• Choose make 1, knit front and back, or yarn over for increases; knit 2 together or slip slip knit for decreases
• Plan sleeve, armhole, and neck shaping over several rows, on right-side rows or every row, at one edge or both
• See the exact shaping rows and the interval between them

Made for real projects
• Quick-start examples for scarves, blankets, hats, yokes, sleeves, and more
• Metric and imperial units, converted as you switch
• Save projects with notes, load them again, and share the result as text

Yarn amounts come from your own swatch, so they follow your yarn, needles, and stitch pattern. Estimates are a guide; a little extra yarn is always wise.
