How Many Stitches Per Inch Is Dk Weight?

5.5 to 6 stitches per inch is the published stockinette range for DK ("double knitting") weight — one step finer than worsted's 4-5 range, one step bulkier than sport's roughly 6-6.5 range.

DK sits at a genuinely useful midpoint

DK weight's position between sport and worsted makes it one of the more flexible weights to substitute with, since a slightly looser DK gauge edges toward worsted's range and a slightly tighter one edges toward sport's — a real practical advantage if you're matching a pattern's gauge with a yarn that isn't labeled exactly DK.

Checking against your own swatch

As with any category range, this number describes typical published gauge, not a guarantee for your specific yarn and hands — swatch before trusting 5.5-6 stitches per inch as your actual number, since individual yarns and knitters both shift where the real figure lands.

How this compares to worsted and sport

Worsted runs looser at 4-5 stitches per inch; sport runs tighter at roughly 6-6.5. This site's DK yarn weight guide gives a full worked example at DK's own midpoint gauge, alongside the same figures for every other weight category.

Stitch pattern still changes the effective number

The range above describes plain stockinette specifically — the same DK yarn worked in a rib, cable, or seed stitch pattern typically produces a different effective gauge than its stockinette number, usually tighter, since textured patterns pull fabric in relative to flat stockinette.

FAQ

Is DK weight the same as "light worsted," a term some patterns use instead? Often used roughly interchangeably by some yarn brands, though "light worsted" isn't a formally standardized CYC category the way DK is — check the yarn's actual stated gauge range rather than relying on the label term alone if the two seem to disagree.

Does DK weight vary more between brands than other weight categories? Not dramatically more, though DK's position between two other common categories (sport and worsted) means some yarns labeled DK sit closer to one neighboring category's typical gauge than to DK's own stated midpoint.

What needle size is typically used for DK weight? Commonly US 6-7 (4-4.5mm), one size finer than worsted's typical US 7-9 range, consistent with DK's tighter stitches-per-inch range.

Does DK-weight crochet use the same stitches-per-inch figure as DK-weight knitting? No — crochet's typical gauge at DK weight runs looser than knitting's, following the same general pattern across every yarn weight where crochet stitches take up more physical space than knit stitches do at a comparable thickness.
