Yarn Weights

  1. Yarn is also broken down to specific types, eight, ply, and WPI. Yarn types include lace, sport, worsted, and chunky, to name just a few. The weight refers to the thickness of the yarn, so the thicker the yarn the less WPI you'll have.

    WPI means wraps per inch, which basically means how many times the yarn can be wrapped around an object in one inch. The opposite is true of ply as the thicker the yarn, the higher the ply. Ply how many strands are twisted together to make the project. Still a bit confused? Check out the charts below!

  2. The infographic below details yarn names, weights, WPI, ply, and even gives you an example of a project to crochet with each type.

  3. Now that you have yarn weight, ply, and WPI under your belt it's time to decide what type of fiber would best for a specific project. If you're planning to make doily, which yarn weight should you choose?

    What about for a crochet baby blanket pattern or winter sweater? Take a look at this chart below to help you figure out which yarn weight goes with what types of patterns.

    In general, the thinner the yarn (lower the weight), the lacier the project. Choosing a yarn at weight 0 and WPI 18 would work well for projects like doilies or fine lace. Sport yarn, with a weight of 2 and a WPI of 14 would work well for baby clothes and light weight sweaters. Get the gist?

Crochet Hook Sizes
