Aran and worsted yarn are not the same, although they are somewhat similar in terms of weight and usage.
What are the uses of the two yarns?
Aran is used for sweaters, particularly Aran sweaters, known for their intricate cable patterns. It is suitable for thick, warm garments and accessories like cardigans, hats, scarves and blankets.
Worsted yarn is also often used for hats, scarves, gloves and blankets. Known for its versatility, it balances warmth and weight, making it suitable for a wide range of items. Worsted yarn is slightly finer and offers versatility for a variety of projects.
When selecting between the two, think about your project, including the desired weight, warmth and texture.
What about weight and thickness?
Aran yarn is a medium-weight yarn that is slightly thicker than worsted yarn. It is generally categorised between worsted-weight and bulky-weight yarns. Aran yarn is often used in the UK and Ireland, where it is a standard term for this particular weight. Aran yarn produces fewer stitches per inch than worsted yarn due to its thicker nature.
Worsted yarn is also a medium-weight yarn but is slightly thinner than Aran yarn. It is a popular weight in the United States and is used for various projects. New York Magazine advises crafting beginners to start with a thicker-knit yarn, anything from a medium worsted-weight to a heavy, chunky yarn.
What needles should be used?
Aran yarn produces a gauge of 16-18 stitches per 10 cm on 4.5-5.5 mm needles. It is good for knitting thicker, warmer garments like sweaters, particularly Aran sweaters, which are known for their intricate patterns.
Worsted yarn typically produces a gauge of 18-20 stitches per 10 cm on 4.5-5.0 mm needles. It creates a medium-density fabric that is versatile for different types of projects.
What can I make?
Create beautiful shawls and wraps that provide warmth without being too heavy with worsted-weight yarn. It can add lovely texture and drape. Aran yarn is perfect for cosy, thick sweaters and cardigans. The yarn’s weight is ideal for showcasing intricate stitches.
