What Is Wraps Per Inch?

Wraps per inch (WPI) is a measurement used in the fiber arts, particularly in knitting, crocheting, and spinning yarn.

It is a way to determine the thickness or diameter of a yarn or fiber.

WPI is useful when you want to match a yarn weight or the gauge of a pattern or create a consistent fabric in your project.

We use it often to check the yarns we use because you can't always go by what is on the yarn label. After all, different manufacturers use different standards.

What You Will Need

  • A ruler
  • The yarn you want to measure

How To Measure Wraps Per Inch

Instructions

  • Unwind a few inches of yarn from the skein or ball to make it easier to work with.
  • Hold the ruler vertically in one hand.
  • Then hold the yarn in your other hand, so it is parallel to the ruler.
  • Begin wrapping the yarn or fiber around the ruler for an inch, maintaining a consistent tension, but not too loose or too tight.
  • Wrap the yarn side by side, without any gaps or overlapping.
  • Once you have wrapped the yarn for an inch, count the number of wraps you have made in that inch and use that number to determine the yarn weight from the chart below.
The yarn in this image has 6 wraps per inch which is equal to #6 super bulky yarn.
