How to Convert a Knitting Pattern's Gauge for Crochet

Found a beautiful knit pattern you'd love to make in crochet instead? The tricky part isn't the stitches, it's matching the gauge so your finished piece comes out the right size.

Knitting and crochet gauge aren't directly interchangeable because the fabric structures differ. Crochet stitches are generally taller and use more yarn per stitch than knit stitches, so a straight stitch-for-stitch swap rarely works.

Here's a practical approach:

1. Note the knitting gauge given in the pattern (stitches and rows per 10 cm/4 in).
2. Calculate the finished measurements the pattern is aiming for, not just the stitch count.
3. Choose a crochet stitch with similar density, like single crochet or half double crochet for a knit stockinette look.
4. Crochet your own gauge swatch using your chosen stitch and hook, then measure it the same way.
5. Do the math from measurements, not stitch counts. Divide the target width by your swatch's stitches-per-cm to find your new stitch count.

Adjust your hook size up or down until your swatch gauge is close to the target. Small gauge differences add up fast over a whole garment, so don't skip this step even if it feels slow.

Once your gauge matches, you can follow the pattern's shaping instructions using your crochet stitch counts instead of the original knit numbers.
