Crochet vs Knitting: Which Uses More Yarn?

Crochet wins — and not in a good way. For the same finished size, crochet typically consumes 25–30% more yarn than knitting. Here's why, and how to adjust your yardage math for whichever craft you do.

Why crochet eats more yarn

It comes down to stitch architecture. A knit stitch is a single interlocking loop; a crochet stitch is a taller, denser knot that wraps yarn around the hook multiple times. Double crochet, treble crochet, and textured stitches like bobbles and popcorns are the hungriest — a heavily textured crochet throw blanket can use 40% more yarn than its knit equivalent.

The 30% rule of thumb

Planning from a knitting pattern or a generic chart? Multiply the yardage by 1.3 for crochet. A knit scarf at 350 yards becomes ~455 yards in crochet; a knit hat at 200 yards becomes ~260. Our project tables are built from knitting-style estimates, so apply the uplift to the calculator's result — or just set the buffer field to 30% when crocheting from a knit pattern.

Stitch choice matters

Not all crochet is equal. Lacy, open stitches (filet, v-stitch, mesh) use less yarn than the 30% rule suggests; dense stitches (single crochet, waistcoat stitch, cables) use more. Tunisian crochet sits between knitting and crochet. If your pattern is stitch-heavy, treat the 30% as a floor and use the 10% buffer rule on top.

What about knitters?

Knitting is the economical craft, but cable and colorwork knitting narrow the gap — stranded colorwork can approach crochet-level consumption. Either way, the habit is the same: calculate for your actual craft, verify against your yarn label's yardage, and buy from one dye lot.

Do knitters ever use more?

Rarely — but it happens. Stranded colorwork carries floats of unused yarn across the back of the fabric, and brioche is famously yarn-hungry: a brioche cowl can use double the yarn of plain stockinette. Cables consume extra too. If your knitting involves any of these techniques, apply the same 30% uplift you would use for crochet.

Which craft is cheaper to start?

Knitting uses less yarn per project, but startup costs differ: knitting needs needle sets in multiple sizes, while crochet needs one hook per project. For a scarf, the yarn gap (350 vs ~455 yards) is about half a skein — a few dollars. Over a blanket, it widens to several skeins. Choose your craft for the fabric you want, not the yarn bill — then calculate honestly for the craft you are doing.

Whatever your craft, the fix is the same: measure honestly for what you are actually making, then buy the buffer.
