Knitting Yardage Estimator
Estimate how much yarn you need for any project. Enter your project type, dimensions, and gauge — get yardage, skeins needed, and a buy buffer recommendation.
How Yardage Estimates Are Calculated
Yarn yardage is estimated from the project surface area and yarn weight, using average consumption figures from published knitting patterns across thousands of garments and accessories. Heavier yarn uses more yards per square centimetre (but covers faster), while lace-weight yarn uses fewer yards per area. The estimates include standard shaping allowances for garments (neckline, armhole, sleeve cap) that reduce the raw surface area.
All estimates include a built-in calculation buffer. The "Buy with 10% buffer" skein count is what you should actually purchase. Always buy an extra skein from the same dye lot — dye lots vary between production batches and buying more later may result in a visible colour mismatch in your finished project.
Why Yardage Varies by Project
Yardage is affected by more than just size. Texture matters: a dense cable pattern uses significantly more yarn than stockinette of the same dimensions (up to 30–40% more). Lace patterns use less yarn than stockinette because the stitches are more open. If your project is textured or has significant colourwork, add another 15–25% to the estimate as a safety margin.
Reading Yarn Label Yardage
Every commercial yarn ball or skein has a label showing both weight (grams) and yardage (metres or yards). Use the yardage figure — not the gram weight — for this calculator. Yarn fibre content affects how much yardage fits in a given weight. For example, 100 g of laceweight merino might be 800 m, while 100 g of bulky acrylic could be only 80 m. The metre/yard figure on the label is the reliable number to use when planning a project.
