Yarn Yardage Calculator
Std. range: 150–220 yds / 100g
Cables and brioche use more yarn; lace uses less.
Check your yarn label — pre-filled with the typical value for the selected weight.
Extra yarn for mistakes, gauge variation, and dye-lot security. 15% recommended.
Select Your Project Details
Choose a project type, yarn weight, and size — then see exactly how many yards you need and how many skeins to buy.
How to Use This Calculator
Choose Your Craft and Project
Select Knitting or Crochet using the craft toggle, then pick your project type from the dropdown. The calculator includes 15 common projects from hats and socks to sweaters and queen-size blankets.
Select Yarn Weight and Size
Click the yarn weight chip that matches your yarn's label (Lace through Super Bulky). Then choose the garment or blanket size. The calculator adjusts yardage automatically — XS uses about 80% of medium, XXL uses 150%.
Set Stitch Pattern and Safety Buffer
Select your stitch pattern from the dropdown — cables add 20%, brioche adds 25%, lace reduces by 10%. Then adjust the safety buffer slider. 15% is recommended for most projects; use 20–25% for colorwork or first-time patterns.
Enter Your Yarn's Label Yardage
Type the yards-per-skein figure from your yarn's label into the 'Yards per Skein' field. The calculator pre-fills a typical value, but your actual yarn may differ. The skein planner will then tell you exactly how many skeins to buy and how many yards from the last skein you'll actually use.
Frequently Asked Questions
Why does crochet use more yarn than knitting?
Crochet stitches are inherently thicker and taller than their knitting equivalents. A single crochet stitch and a knit stitch may produce the same width of fabric, but the crochet stitch consumes significantly more yarn because the hook wraps yarn around the working loop in a way that creates more bulk. Double crochet, granny squares, and most common crochet stitch patterns use roughly 25–35% more yarn than stockinette knitting for the same finished dimensions. This is why this calculator applies a 1.30× multiplier when you select Crochet — it prevents you from being caught short mid-project when following a knitting-to-crochet conversion.
What is a dye lot and why does it matter?
A dye lot is a batch of yarn that was dyed at the same time in the same vat. Even yarns with identical colorway names can look subtly different if they come from different dye lots — the variation becomes obvious when two skeins are knitted side by side in a sweater or blanket. Most yarn labels print a dye lot number; you should buy all your skeins from the same lot number. If a retailer can't guarantee lot matching, err on the side of buying one extra skein. The safety buffer in this calculator is specifically designed to help you buy enough in a single purchase so you don't need to hunt for matching lot numbers later.
How do I use this calculator if my yarn weight is between two categories?
When your yarn sits between two standard weight categories — for example, a heavy DK that behaves like a light worsted — calculate using both weights and split the difference. Most pattern designers use a 10% variance window within each weight category. If your yarn's gauge swatch puts you between DK and worsted, average the yardage estimates for both and add an extra 5% to your safety buffer to account for the uncertainty. Alternatively, use the stitch pattern multiplier to fine-tune: a loosely-spun yarn will often behave closer to the lighter weight category even at the same wraps-per-inch.
Should I adjust the safety buffer for cables or colorwork?
Yes — for cable-heavy projects, consider setting the buffer to 20–25%. Complex all-over cable patterns can easily consume 25–30% more yarn than stockinette, and the stitch pattern multiplier of 1.20× only captures the average cable impact. Colorwork and stranded patterns also warrant a higher buffer — particularly if you're carrying two yarns throughout the project, as the floats on the wrong side add significant yardage. For projects where yardage is critical (matching handspun skeins, limited-edition yarn), always err toward a 25–30% buffer. Running out of a special yarn mid-project is far more costly in time and money than buying one extra skein upfront.
What is the difference between buying by yardage vs. skein count?
Skein count is a derived number — it only tells you how many skeins to buy if you already know the yardage per skein. Two skeins of 'worsted weight' from different brands might have 150 yards or 220 yards each — a 47% difference. If you plan a project based on '5 skeins' without knowing the yardage, you may end up with far too little or far too much. Always plan by total yardage first, then divide by your specific yarn's label yardage to get skein count. This calculator does that math for you once you enter the yards-per-skein from your label.
Can I use this calculator for yarn substitution?
Yes — this is one of the most useful applications. If a pattern calls for a specific yarn but you want to substitute, note the total yardage required by the pattern, then use this calculator's yarn weight comparison chart to see whether your substitute yarn provides enough yardage at its own standard skein count. For example, if a pattern calls for 1,200 yards of DK and you want to substitute a sport weight, the comparison chart will show you that sport weight typically requires about 1,575 yards for an equivalent project — so you'll need to buy more skeins. Always match gauge, not just weight category, and calculate yardage accordingly.
