Worsted and Aran Yarn: medium-to-heavy-weight yarns

It is a very versatile weight for garments and accessories with body: jumpers, cardigans, ponchos, hats, cowls, scarves and blankets. It also works very well for large amigurumi and home décor pieces. Aran yarn, being slightly thicker, creates even more pronounced stitches, while worsted is a little lighter.

For worsted weight, 4.5 to 5.5 mm needles are recommended, and for aran, 5 to 6 mm. These are guidelines: it is worth adjusting them to the pattern and your personal tension. With these sizes, you will achieve a fabric with body, good drape and well-defined stitches, forgiving even if you have little experience.

As a guide, worsted weight yarn usually gives between 150 and 200 metres per 100 grams. Aran yarn gives a little less, between 135 and 180 metres, because it is slightly thicker. Always check the yardage of each aran or worsted weight yarn on its label before calculating the balls for your project.

Yes. Worsted is one step thicker than DK weight: it is worked with slightly larger needles and the garment gains body and works up faster. If your pattern calls for a slightly finer yarn, you will find many options in DK weight. The difference is small, but it shows in the drape and in how many balls you will need.

Yes, it is one of the most rewarding weights for both techniques. In knitting, it shows off cables, lacework and textured stitches; in crochet, it adds volume and speed to bags, baskets, blankets and large amigurumi. Its medium-to-heavy weight means you see progress straight away, which is very practical whether you are just starting out or already knit with confidence.
