Sport weight is category 2 in the Craft Yarn Council system, a step lighter than DK and a step heavier than fingering. It gives a finer, more detailed fabric than worsted while still working up faster than true fingering or lace. That balance makes it a favorite for baby garments, lightweight sweaters, and accessories where you want stitch detail without bulk.
Hooks for sport weight run 3.5 to 4.5 mm and needles 3.25 to 3.75 mm. Because the fabric is finer, projects take longer than in worsted, so it suits makers who enjoy a more delicate result. Substituting sport for DK, or holding two strands of fingering together, are common ways to hit a sport gauge when a pattern calls for it.
