Understanding Yarn Calculations

What is Gauge?

Gauge refers to the number of stitches and rows per inch in your knitting. It's the most critical measurement for accurate yarn calculations.

  • • Always knit a 4x4 inch gauge swatch
  • • Use the same yarn and needles as your project
  • • Block your swatch before measuring
  • • Measure in the center of the swatch
