Sport Yarn: Medium-weight yarns for knitting

Sport weight yarn is usually worked with 3 to 4 mm needles or crochet hook. With 3 to 3.5 mm you achieve a firmer, more defined fabric, ideal for amigurumi and baby garments; with 3.5 to 4 mm, a more fluid drape for tops and lightweight cardigans.

A ball of sport yarn usually comes in 50 or 100 gram formats. As a guide, in 100 grams you will find between 250 and 350 metres, depending on the fibre and brand. It is an efficient yardage that lets you make medium and large projects without too much weight.

Sport yarns occupy a middle point on the scale. They are slightly thicker and have more body than fingering yarn, making it easier to create a faster fabric with better stitch definition.

At the same time, sport weight yarn is lighter than DK yarns, so it is ideal when you are looking for transitional-season garments with good drape and without too much weight. If you are unsure, you can compare each option and choose the right weight for your project.
