Yarn Calculator — How Much Yarn Do I Need?
Estimate the yardage, meters, and number of skeins your crochet project needs.
How to use this tool
- Pick your project type — denser stitches (amigurumi) use much more yarn than a flat blanket of the same size.
- Enter the finished width and height and choose your units.
- Select your yarn weight and the yards per skein printed on your yarn label.
- Press Calculate to see the yards, meters, and number of skeins needed (with a safety buffer).
This is an estimate based on typical yarn consumption per area. Your exact amount depends on your tension and stitch pattern, so round up — running out mid-project from a different dye lot is the most common yarn mistake.
Frequently asked questions
How do I know how much yarn I need for a crochet project?
Multiply your project area by the yarn needed per square unit for your gauge and yarn weight. This calculator does it for you — enter your dimensions, gauge, and yarn weight, and it returns the yards, meters, and number of skeins required.
Why should I add extra yarn?
Always buy 10–15% more than the estimate. Tension varies, borders and seams use extra, and dye lots can differ between purchases, so a small buffer prevents running out mid-project.
What is a skein and how many yards are in one?
A skein is a single packaged unit of yarn. Yardage per skein varies a lot by brand and weight — commonly 170–220 yards for worsted weight. Enter your skein size for an accurate skein count.
