Knitting Gauge Calculator
Enter stitches and rows in a measured knit swatch to see gauge per 10 cm and stitches for a target width.
How to calculate knitting gauge
Knitting gauge works like crochet gauge: count stitches and rows over a measured, blocked swatch, normalise to stitches and rows per 10 cm, then scale to the garment width you need before casting on. Needle material, yarn batch and blocking method all shift results, so the swatch must match the finished care routine. Round stitch counts to pattern repeats when cables or lace demand it. After you lock width, estimate yarn with the yarn calculator; crocheters can use the sibling crochet gauge page for hook-based fabrics.
Worked example
24 stitches over 10 cm → 24 per 10 cm. Target width 45 cm → about 108 stitches.
Limits and assumptions
Row gauge affects length more than width; always check both. Pattern ease is not applied automatically.
Frequently asked questions
What is knitting gauge?
Gauge (tension) is how many stitches and rows you knit in a set measurement, commonly per 10 cm, so the finished size matches the pattern designer’s assumptions.
Stockinette versus pattern stitch?
Swatch in the stitch pattern the gauge note specifies — cables pull in differently from plain stockinette.
Flat or in the round?
Many knitters swatch in the round if the garment is circular, because tension can differ.
What if I am between needle sizes?
Recalculate project stitches from your measured gauge rather than forcing the pattern’s numbers.
