What is Aran Weight Yarn? A Beginner's Guide

Aran weight yarn is a medium-weight yarn that is slightly heavier than worsted weight yarn but lighter than bulky weight yarn. Classified as a category 4 yarn in the Craft Yarn Council's standard yarn weight system, Aran weight yarn typically has a wraps per inch (WPI) of about 8 and is commonly knitted or crocheted using needles or hooks sized between 5mm to 6mm (US sizes 8 to 10). This type of yarn is versatile and well-suited for various projects, including sweaters, cardigans, hats, and scarves, making it a favorite among crafters.

The term "Aran" originates from the Aran Islands off the west coast of Ireland, known for their traditional cable-knit sweaters. While Aran weight yarn is often confused with worsted weight yarn, it is important to note that Aran yarn is generally thicker and loftier, resulting in a different gauge. This distinction allows for beautiful stitch definitions, particularly in textured patterns and cables, making Aran weight yarn an excellent choice for warm, cozy garments and accessories that require both durability and style.

While Aran and worsted weight yarns are often used interchangeably, there are subtle differences between the two.

• Thickness and Gauge: Aran weight yarn is generally thicker than worsted weight yarn, resulting in a smaller gauge. For example, a typical worsted weight yarn may have a gauge of 18 stitches per 4 inches, while Aran weight yarn may have a gauge of 16 stitches per 4 inches. This difference in thickness can affect the overall size and fit of finished projects, particularly garments.
• Needle Sizes: The recommended needle sizes for these yarns also differ slightly. Worsted weight yarn is commonly knit using US size 7 (4.5mm) needles, while Aran weight yarn typically requires US size 8 (5mm) needles. This means that if you are substituting one for the other in a pattern, you should pay close attention to the gauge to ensure that your finished item meets the desired dimensions.
• Regional Variations: In the UK, the term "Aran" is more widely used than "worsted" to refer to medium-weight yarns. As a result, some yarns that are labeled as worsted in the US may be categorized as Aran in the UK. Therefore, when using patterns from different regions, it is essential to check the gauge and yarn recommendations to ensure compatibility.

Aran weight yarn can be made from various fibers, each offering unique properties and characteristics. Here are some common types of Aran weight yarn based on fiber content:
