Yarn Skein Calculator
Round a length requirement and extra allowance to whole skeins.
What would you like to do next?
Convert a pattern length into packages to purchase
Enter the yarn length required by a pattern, length on one skein or ball, an extra percentage, package weight and price. The calculator adds the allowance, divides by labeled length and rounds up to a whole package. It then shows total labeled length, approximate purchased weight and estimated cost for the rounded quantity.
Match yarn specifications before buying
Keep yards with yards or meters with meters, and compare fiber, weight category, gauge and yardage rather than package count alone. Swatching, size changes, stitch pattern, dye lot, substitutions, knots and mistakes can all change the amount required.
Frequently asked questions
Does the skein count round up?
Yes. The purchase quantity is always a whole package.
Can I mix yards and meters?
No. Requirement and per-skein length must use the same unit.
Does equal skein count mean equal yarn?
No. Compare labeled length, weight and yarn specification.
