Aran Weight Yarn

Aran weight yarn is a versatile, medium-to-heavy yarn that’s perfect for cozy sweaters, blankets, hats, and scarves. Often referred to as “worsted weight’s heavier cousin,” Aran yarn strikes the perfect balance between warmth and structure, making it one of the most popular yarn weights among knitters and crocheters. It typically works up beautifully on 4.5–5.5 mm (US 7–9) needles or hooks, creating a substantial fabric that feels soft yet durable.

Because of its thickness and easy handling, Aran weight yarn is ideal for quick-to-finish projects and for showing off texture—especially cables, ribbing, and other dimensional stitch patterns. It’s a go-to choice for fall and winter garments that provide real warmth without feeling overly bulky. Below are some of our most popular Aran weight yarns.

What Can You Make with Aran Weight Yarn?

Aran weight yarn is perfect for sweaters, cardigans, blankets, and accessories like hats, mittens, and scarves. Its stitch definition makes it an excellent choice for traditional Aran and Fisherman-style patterns, where cables and textured stitches really stand out.

Many Aran yarns are spun from natural fibers like wool, merino, or alpaca, giving projects softness, elasticity, and warmth. Some blends include acrylic or nylon for added durability and easy care—great for everyday wear and family knits.

Whether you’re a beginner looking for a forgiving yarn weight that works up quickly, or an experienced crafter creating heirloom-quality knitwear, Aran weight yarn delivers versatility, comfort, and timeless appeal.
