Skein calculator
Turn the yarn length in your pattern into a practical number of skeins, with an optional margin for swatching and small variations.
How the skein calculator works
The calculator divides your required yarn length by the length in one skein. It then rounds up to a whole skein after applying the safety margin you choose.
Worked example
A project needs 2,430 meters and each skein contains 120 meters. With no additional margin, 2,430 ÷ 120 = 20.25, so you should purchase 21 skeins.
Frequently asked questions
Should I add a safety margin?
A 5–10% margin is useful when your tension may differ, you plan to swatch, or dye-lot availability is limited.
Why does the calculator round up?
Yarn is sold in complete skeins, so any partial result needs one additional skein.
Can I use yards instead of meters?
Yes. Keep both length inputs in the same selected unit and the result will use that unit.
