About This Tool
The Yarn Calculator takes the guesswork out of buying yarn for your next knitting or crochet project. Select your project type, choose a yarn weight, and get an instant estimate of how many skeins to buy.
How Yardage Estimates Work
Our estimates are based on average yardage for standard project sizes using the most common yarn weight for each project type. Your actual yardage may vary based on your gauge, stitch pattern (cables use more yarn than stockinette), and personal tension.
Choosing the Right Yarn Weight
Worsted weight (4) is the most versatile and widely available. Lighter weights (fingering, sport) create drapier fabric and work well for garments. Bulkier weights work up faster and are great for blankets and accessories. Always check your pattern's recommended weight.
