Yarn Calculator: How Many Skeins Do I Need?
Enter the yarn length your knitting pattern requires and the length printed on one skein's label. This free calculator converts meters and yards automatically, rounds up to whole skeins, and can include extra yarn for a safety margin.
With 10% extra: 935.0 m (1022.5 yd) needed divided by 200.0 m (218.7 yd) per skein = 4.68, rounded up to 5.
Please enter positive numbers for both yarn lengths.
This estimates skeins by length, not weight. Check that your chosen yarn matches the pattern's gauge, fiber, and thickness. The same weight in grams does not guarantee the same yardage. For multicolor projects, calculate each color separately.
How to Use the Yarn Calculator
- Find the total yardage or meterage required by your knitting pattern.
- Read the meters or yards per ball on the yarn label.
- Choose the correct unit for each field; they can be different.
- Select an optional allowance, then read the recommended number of whole skeins.
Frequently Asked Questions
Can I enter yards for one field and meters for the other?
Yes. The calculator converts between them before dividing.
Why does the result round up?
Yarn is normally purchased in whole skeins, so a fraction of a skein is rounded up.
Do I always need 10% extra yarn?
No. Extra yarn is optional, but it may help when your gauge differs, you change the design, or you want a safety margin.
Can I use this calculator for crochet projects?
Yes, if you know the total length of yarn required by your crochet pattern. The calculation is based on length rather than knitting technique.
