Aran Weight Yarn

 

Aran sits between worsted and bulky — heavier and faster to knit than worsted, with enough stitch definition to show off cables and texture clearly. This collection includes classic wool arans, tweed-flecked options, and a few farm and mill-specific bases, making it a good starting point for traditional cabled sweaters, jackets, and outerwear.

Aran weight typically knits at 16–18 stitches per 4 inches on US 8–9 (5–5.5mm) needles, making it heavier than worsted but lighter than bulky. The name comes from the cabled sweaters traditionally knit in this weight, and it remains the go-to choice for cable work, since the thicker stitches make traditional cable and texture patterns easier to see and knit accurately.

This collection includes a range of wool bases — some superwash and machine washable, others not — along with a few tweed-textured yarns and blends that add visual interest without changing the weight category. Aran and heavy worsted are close enough in thickness that some yarns are labeled as both; check the individual product page if you're matching a specific pattern's gauge.

Because aran knits up quickly and holds cable and texture patterns well, it's a practical choice for outerwear, jackets, and heavier sweaters where you want both warmth and visible stitch detail.

Frequently asked questions

What's the difference between aran and worsted weight?

Aran is slightly heavier than worsted. Worsted typically knits at 16–20 stitches per 4 inches, aran at 16–18, so there's overlap between the two and some yarns are labeled as both. A gauge swatch is the reliable way to tell if one will substitute for the other in a specific pattern.

Is aran weight yarn good for cable knitting?

Yes — aran is the traditional weight for Irish cable sweaters, and its thickness makes cable crossings and texture stitches easier to see and knit accurately compared with finer yarns.

How much aran weight yarn do I need for a sweater?

Most adult sweaters take 900–1,400 yards depending on size and style, though this varies with pattern, gauge, and fit. Intricate cables will use more yarn than a plain knit. Always check the specific pattern's yardage requirement.
