Yarn by Weight

Yarn by Weight

Achieving the correct gauge starts with choosing the right yarn by weight.  See the full yarn weight chart with ply conversions. Whether you are following a pattern that calls for delicate lace or a trendy, oversized chunky knit, our collection makes it simple to filter yarns to find exactly what you need.   From "Category 0" threads to "Category 7" jumbo roving, we carry all types of yarn weight to ensure your finished project has the perfect drape, warmth, and stitch definition.  Use our weight filters below to explore your favorite fibers in the specific thickness your pattern requires. 

Lace: > 8 sts or > 8 sc  = 1" | Fingering: 7–8 sts or 5.25–8 sc = 1" | Sport: 6–6.75 sts or 4–5 sc = 1" | DK: 5.25–6 sts or 3–4.25 sc = 1" | Worsted: 4–5 sts or 2.75–3.5 sc = 1" | Heavy Worsted/Aran: 4 sts or 2.75–3.5 sc = 1" | Bulky: 3–3.75 sts or 2–2.75 sc = 1" | Super Bulky: < 2.75 sts or 1.75–2.25 sc = 1"

Please note that Novelty yarns vary, so be sure to check the yarn specifications for your project.

Understanding Different Types of Yarn Weight

In the world of fiber arts, "weight" refers to the thickness of the yarn strand rather than the physical heaviness of the ball. Standardized yarn weights help crafters substitute fibers while maintaining the same scale. If your pattern calls for a specific weight and you aren’t sure where to start, here is a quick guide to the most common categories:

  • Lace & Fingering (Weights 0-1): These ultra-fine yarns are the best yarn for socks, lightweight shawls, and intricate lace edgings.
  • Sport & DK (Weights 2-3): Often called "lightweight" yarns, these are versatile favorites for baby clothes, spring cardigans, and stranded colorwork.
  • Worsted & Aran (Weight 4): This is the most popular yarn weight, prized for its balance of speed and stitch definition—ideal for sweaters, blankets, and hats.
  • Bulky & Super Bulky (Weights 5-6): Perfect for quick-knit gifts, these thick fibers create warm, cozy textures that work up in a flash on large needles or hooks.

Why Does Yarn Weight Matter?

Selecting the correct weight isn't just about the look; it’s about achieving gauge. If the yarn is too thin, your sweater will be too small; if it’s too thick, your project will be stiff and oversized. By matching your yarn weight to the designer's recommendation, you ensure the drape, durability, and size are exactly where they need to be.

Expert Tip: Always check your ball band! Most manufacturers list the Craft Yarn Council (CYC) number (0–7) right on the label to help you identify the weight at a glance.

How to Verify Your Yarn Weight: WPI and Gauge

If you have a mystery skein in your stash, you can determine its weight by measuring Wraps Per Inch (WPI). By wrapping the yarn snugly around a ruler, you can count how many times it fits into an inch to identify its category. We’ve also included the typical knitting gauge below to help you cross-reference your results and ensure your chosen pattern will have the perfect drape and fit.

Lace Weight: 18+ WPI, 32–40+ sts / 4"

Fingering Weight: 14–18 WPI, 27–32 sts / 4"

Sport Weight: 12–14 WPI, 23–26 sts / 4"

DK Weight: 11–13 WPI, 21–24 sts / 4"

Worsted Weight: 9–11 WPI, 16–20 sts / 4"

Heavy Worsted / Aran: 8–9 WPI, 16–18 sts / 4"

Bulky Weight: 6–8 WPI, 12–15 sts / 4"

Super Bulky: 5–6 WPI, 6–11 sts / 4"
