How to Use This Calculator

  • Select a scarf style preset or enter your own dimensions.
  • Enter your gauge in stitches per inch and rows per inch from your swatch.
  • Select your yarn weight for a yardage estimate.
  • Click Calculate to see your stitch count, row count, and yarn needed.

Tips

  • For an infinity scarf, the "length" is the total circumference of the loop (usually 55–65").
  • Lacy or open stitch patterns may use more yarn than plain stockinette or sc/dc for the same area.
  • Add fringe yardage separately — typically 2–3× the width of the scarf per fringe segment.
