Double Crochet: Repeat, Multiple and How to Work It
Double crochet yarns over before inserting the hook, pulls up a loop, then completes the stitch across two separate pull-throughs rather than one — a taller, more open stitch than single crochet or half double crochet, and the workhorse of most garment and blanket crochet.
No fixed multiple, standard turning chain
There's no fixed repeat multiple to satisfy — double crochet works over any foundation count. Its turning chain-3 is more consistently treated as counting as the first stitch of the row than half double crochet's more ambiguous chain-2, a genuine source of relief for anyone who's been tripped up by that stitch's less settled convention.
Why per-stitch yarn use and per-area yarn use aren't the same question
Each individual double crochet stitch takes more yarn to form than a single crochet stitch does — two full wraps and pull-throughs instead of one shorter pass, and this site's own calibration puts double crochet's per-stitch constant higher than any other pattern it tracks. But a finished double crochet fabric also needs meaningfully fewer stitches to cover the same square inches, since each stitch is taller and the fabric itself sits more open at its typical gauge. Those two effects pull in opposite directions, and — worked through in full on the methodology page — the honest answer is that they roughly cancel: our own calibration, checked against real published double crochet projects, lands double crochet's yarn use per square inch close to stockinette's rather than clearly above or below it. That's close enough that it isn't something to guess at from the stitch mechanics alone for a specific yarn and gauge — weighing your own real fabric, the Yarn Quantity Estimator's "I weighed my swatch" option, is the accurate path.
What this means for substituting stitches in a pattern
Don't assume a taller stitch is automatically the cheaper or more expensive choice in total yardage — both directions are physically plausible depending on the specific stitch and gauge, and the honest answer is to weigh a real swatch rather than reason it out from "taller stitch, fewer stitches" alone.
Where it's used
Garments, blankets, and grannysquare-adjacent motifs where speed and drape both matter more than single crochet's dense structure. It's the default "fast" crochet stitch the way worsted weight is the default "fast" knitting weight — most beginner-to-intermediate crochet patterns lean on it heavily.
Common mistakes with double crochet
Skipping or double-counting the turning chain-3 as the first stitch. Because most patterns do count it, forgetting to work into (or skip past) the correct stitch at the row's end is a common source of a slowly growing or shrinking stitch count.
Working too loosely and losing stitch definition. Double crochet's taller structure can look sloppy at a very loose tension in a way shorter stitches disguise better — a consistent, moderate tension matters more here than in single crochet.
FAQ
Is US "double crochet" the same stitch as UK "treble crochet"? Yes — this is the double crochet counterpart to the single-crochet/UK-double-crochet naming offset. What Americans call double crochet, British patterns call treble crochet.
Does double crochet work well for amigurumi? Not typically — its more open structure lets stuffing show through more easily than single crochet's tight fabric, which is why amigurumi patterns favor single crochet (often at a smaller-than-usual hook) almost universally.
Is double crochet faster to work than single crochet for the same size project? Generally yes — a double crochet piece needs fewer, taller stitches to fill an identical area, so it finishes in noticeably fewer stitch-by-stitch repetitions than the same project in single crochet, even accounting for double crochet's extra pull-through step per stitch.
