Enter the width of the project, stitch rate, and stitch width into the calculator to determine the number of stitches needed.

Knitting Stitch Formula

The following formula is used to calculate the number of stitches needed for a knitting project.

SN = (W * SR) / SW

Variables:

  • SN is the number of stitches needed
  • W is the width of the project (inches)
  • SR is the stitch rate (stitches per inch)
  • SW is the stitch width (inches)

To calculate the number of stitches needed for a knitting project, multiply the width of the project by the stitch rate. Then divide the result by the stitch width.

What is a Knitting Stitch?

A knitting stitch is a loop of yarn that is manipulated using knitting needles to create a fabric or textile. There are various types of knitting stitches, each producing different textures and patterns, such as the knit stitch, purl stitch, garter stitch, and stockinette stitch. The process involves pulling a loop of yarn through an existing loop on the needle, which creates a new loop and extends the fabric. The combination and sequence of these stitches form the basis of knitting.

How to Calculate Knitting Stitch?

The following steps outline how to calculate the number of stitches needed for a knitting project.


  1. First, determine the width of the project (W) in inches.
  2. Next, determine the stitch rate (SR) in stitches per inch.
  3. Next, gather the formula from above: SN = (W * SR) / SW.
  4. Finally, calculate the number of stitches needed (SN).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Width of the project (W) in inches = 10

Stitch rate (SR) in stitches per inch = 5

Stitch width (SW) in inches = 2
