Crochet Gauge Calculator — Stitches & Rows per Inch
Check your gauge from a swatch and see if you need to adjust your hook size.
How to use this tool
- Crochet a swatch at least 6 in (15 cm) square in the pattern stitch and block it.
- Count the stitches and rows across a measured section in the middle of the swatch.
- Enter the size of the section you measured.
- Optionally add the pattern's target gauge to get a hook size recommendation.
If you have more stitches per inch than the pattern, your tension is tight — go up a hook size. Fewer stitches means loose tension — go down a hook size. Re-swatch until it matches.
Frequently asked questions
What is gauge in crochet and why does it matter?
Gauge is the number of stitches and rows in a given measurement (usually 4 inches / 10 cm). Matching the pattern gauge ensures your finished project comes out the right size — if your gauge is off, so are your measurements.
How do I fix my gauge if it does not match the pattern?
If you have too many stitches per inch, your tension is tight — go up a hook size. If you have too few, your tension is loose — go down a hook size. Re-swatch and measure again until it matches.
How big should my gauge swatch be?
Make a swatch at least 6 inches (15 cm) square, then measure the gauge in the middle, away from the edges, for the most accurate reading.
