Bulky / chunky yarn

Chunky commonly corresponds to category 5, bulky yarn. Its typical stockinette range is 12–15 stitches over four inches, with fewer stitches across the same width than medium yarn.

Gauge and tools

Category: 5
Common names: Chunky, craft, rug
Stockinette stitches per 4 inches: 12–15
Needles (mm): 5.5–8
Hooks (mm): 6.5–9

These are starting ranges. Follow the gauge in your pattern and measure the washed fabric.

Working with this weight

Thicker accessories and substantial fabric. Try a sample against the intended use: a thick scarf must bend comfortably, while a bag needs enough structure to keep its shape. Check seams and folded edges because multiple fabric layers add noticeable bulk.

Compare a replacement

Bulky and super bulky are adjacent categories, not interchangeable labels. A thicker substitute can alter the width substantially even when the same needles can physically work both strands.

Calculate replacement yarn and compare washed gauge

Worked check

A 30-stitch scarf at 15 stitches per four inches is eight inches wide. At 12 stitches per four inches the same count becomes ten inches, a 25% increase.
