Broken Rib: Repeat, Multiple and How to Work It
Broken rib alternates one full row of rib with one full row of plain knitting — a genuinely simpler pattern to memorize than true ribbing, at the cost of most of true ribbing's elasticity.
The repeat
The stitch count requirement is identical to 1x1 rib's — an even total, a multiple of 2. Row 1 is a standard rib row (*k1, p1* across); Row 2 abandons the alternation entirely and simply knits every stitch. Repeat those two rows. Unlike true 1x1 rib, Row 2 never mirrors Row 1's pattern — it just knits straight across, which is exactly what "breaks" the rib structure.
Why breaking the rib every other row changes the fabric so much
True 1x1 rib gets its elasticity from unbroken vertical columns of knit and purl stitches pulling against each other continuously up the fabric. Broken rib interrupts that column every second row with a plain knit row, which stops the columns from ever fully forming — the result is a flatter, less springy fabric that reads visually similar to rib at a glance but behaves much closer to a lightly textured stockinette in practice.
Why some knitters prefer it anyway
Broken rib is genuinely easier to memorize and knit without constant attention than true ribbing — Row 2 requires no stitch-by-stitch tracking at all, just plain knitting, which makes broken rib a common choice for knitters who want rib's visual texture without rib's sustained concentration demand, or for a project meant to be portable, low-attention knitting.
Where it's used
Scarves and blankets where a light, rib-adjacent texture is wanted without true ribbing's pull-in, and as a beginner-friendly alternative to 1x1 rib for a first textured project, since half of every repeat is simply plain knitting.
Common mistakes with broken rib
Accidentally working Row 2 as a rib row instead of plain knit. This is the single most common error, and it silently converts the pattern into true 1x1 rib — check your row count against the pattern rather than relying on the fabric looking "close enough" to broken rib's intended appearance.
Expecting rib-level stretch from broken rib. Because the pattern is explicitly less elastic than true ribbing, using it for a cuff or brim that depends on strong negative ease to fit snugly will produce a looser result than the equivalent true-rib edge.

FAQ
Is broken rib the same as "half fisherman's rib"? Not the same pattern — fisherman's rib uses a distinct knit-below technique for its texture, while broken rib is built from ordinary knit and purl stitches alternating in the row-based pattern described above.
Does broken rib need a smaller needle than the surrounding fabric, the way true rib sometimes does? Not typically — since it doesn't rely on tight elasticity the way true rib does, there's less reason to size down specifically for a snugger fit.
