Every tool a maker actually needs

Yarn Calculator

Your pattern gives you a yarn name. Not a skein count. Enter your yardage and weight, Yarnzy returns the exact number of skeins. Not a guess. The real number.

Stitch Calculator

Know your gauge. Know your width. Yarnzy does the one calculation every knitter skips and every frogged project proves they shouldn't have.

Unit Conversion

Meters to yards. Grams to ounces. Your pattern is European, your yarn is American, Yarnzy makes both speak the same language instantly.

Yarn Substitution

Your pattern's yarn is discontinued. Enter your yardage and weight, get the exact skein count for whatever yarn you're swapping in. Before you buy anything.

Increase & Decrease Calculator

Even shaping doesn't happen by feel. Enter your stitch count and rows, Yarnzy spaces every increase and decrease so your finished piece shows it.
