What does double high mean?

One stitch pattern, a different look. Double high repeats each pattern row twice, stretching the design vertically without changing its width. It’s a simple way to get more from the stitch patterns you already have.

Double high repeats each row of your stitch pattern twice, making the design taller without changing its width. On punchcard machines, this is often called double length.

Same stitch pattern, different proportions. Double high repeats each pattern row twice, making the elephant taller without making it wider.

Why This Works

Double high repeats each row of the stitch pattern twice before advancing to the next pattern row. This stretches the design vertically without changing the number of stitches across it.

Your machine may call this double high or double length.

Electronic machines may offer other variations, such as double width, mirror image, or reverse. Available options depend on your model.

Explore the Variations Reference Guide to see how these options change a stitch pattern’s appearance.

Try This

  • Choose a simple stitch pattern and knit a few inches.
  • Switch to double high (double length), following your machine’s manual.
  • Knit a few more inches using the same yarn and tension.
  • Compare the two sections. How did the design’s height, proportions and gauge change?

Double high changes the stitch pattern’s proportions, not your garment’s measurements. Swatch in double high before measuring gauge for your project.
