🧶 How to Know If Yarn Is Chunky?
If you’re holding a skein and wondering, “Is this chunky yarn?” — you’re not alone. Here’s a practical guide to help you confidently identify chunky yarn (even if you’ve lost the label).
📊Side-by-Side Yarn Thickness Guide
| Yarn Weight | Typical Thickness (mm) | Feels Like |
|---|---|---|
| Lace | ~0.5–1 mm | Very thin, like sewing thread |
| Fingering | ~1 mm | Thin, used for socks or baby clothes |
| DK (Double Knit) | ~2–3 mm | Medium-light |
| Worsted/Aran | ~3.5–4.5 mm | Medium, soft but not too thick |
| Chunky | ~5–6 mm | Thick, squishy, and warm |
| Bulky | ~6.5–7 mm | Thicker than chunky, sometimes ropelike |
| Super Bulky/Jumbo | 8 mm+ | Huge stitches, blanket yarn |
📏Try the Wraps Per Inch (WPI) Test
Here’s how to test yarn thickness manually:
- Take a ruler or pencil and a small piece of yarn.
- Wrap the yarn around a 1-inch section without stretching it.
- Count how many wraps fit in that inch.
| Yarn Type | Wraps per Inch (WPI) |
|---|---|
| Worsted | 9–11 |
| Chunky | 6–8 |
| Bulky | 5–6 |
🧠“Is This Chunky?”
- Stitch Size: Large, visible stitches with gaps between each one.
