ℹ️ Always knit a swatch: stitches = (sts/10) × width, rows = (rows/10) × height. 100% local.

Plan your knitting from the gauge

Enter the stitches and rows measured over 10 cm, then the width and height you want: the tool gives the stitches to cast on and rows to knit.

The method

  • Stitches = (sts/10 cm) × width
  • Rows = (rows/10 cm) × height
  • Always block the swatch before measuring
  • Re-swatch if you change needle size

Frequently asked questions

How do I make a swatch?

Knit a square and count the stitches and rows over 10 cm in the centre. That is your gauge.

How are cast-on stitches calculated?

Stitches = (stitches per 10 cm ÷ 10) × target width in cm. E.g. 22 sts/10 cm × 50 cm = 110 stitches.

Why is my garment the wrong size?

Usually the swatch was skipped: change needle size until you match the pattern’s gauge.

What about rows?

Rows = (rows per 10 cm ÷ 10) × target height in cm.
