Chunky yarn is the common name, especially in the UK, for what the Craft Yarn Council labels category 5, which the US often calls bulky. The two terms point to the same thickness. It works up fast because each stitch covers more ground, so a chunky hat can be finished in an evening and a blanket in a weekend.
The recommended hook is 6.5 to 9.0 mm, and knitting needles run roughly 5.5 to 8.0 mm. Gauge in single crochet is about 9 to 11 stitches per 4 inches (10 cm). Because the stitches are large, chunky yarn is forgiving for beginners who want a quick, satisfying result, though fine detail and crisp stitch patterns show better in thinner yarns.
