A gentle guide to crochet gauge

Gauge is the number of stitches and rows in a set measurement, usually 10 cm (4 in). It’s the single number that decides whether a finished item comes out at the size the pattern promises.

How to measure it

1. Make a swatch at least 15 cm (6 in) square, in the stitch the pattern uses.
2. Wash and block it the way you will wash the finished piece.
3. Lay it flat. Measure the stitches across 10 cm in the middle, away from the edges.
4. Count the rows in 10 cm as well.

Adjusting

If you have more stitches than the pattern says, your work is tighter. Try a larger hook. If you have fewer stitches, try a smaller hook. Change one size at a time.

When gauge matters

For anything that has to fit, such as garments, hats and bags with a set size, gauge is essential. For scarves, dishcloths and blankets, being a little off is fine. For amigurumi, keep the stitches tight enough that the stuffing does not show.

A swatch feels like a delay, but it takes an hour, and can save weeks of unravelling.
