How to Use the Gauge Calculator

Calculate Gauge Tab

Knit or crochet a swatch of at least 4"×4" (10×10 cm) in the stitch pattern you plan to use.
Count the number of stitches and rows within a measured area.
Enter those counts and the measured dimensions to get your gauge.

Adjust for Pattern Tab

Enter the gauge from the pattern (usually listed as "X sts over 4 inches").
Enter your actual gauge from your swatch.
Enter the pattern's cast-on number or the width you want.
The calculator will tell you how many stitches to cast on so your project comes out the right size.

Tips

Always wash and block your swatch before measuring — many yarns change size after washing.
Measure from the center of your swatch, not the edges, for the most accurate result.
If your gauge is tighter than the pattern (more stitches per inch), try a larger needle or hook.
If your gauge is looser (fewer stitches per inch), try a smaller needle or hook.
