Yarn weight guide

Sport

The forgotten middleweight. Sport is heavier than fingering and lighter than DK — beautiful for a refined cabled pullover or a child's cardigan, but sometimes hard to source.

About this weight

Sport's typical gauge of 24 sts to 4 inches gives it more drape than DK and more visible stitch definition than fingering. Cables in sport-weight wool are crisp without being heavy; lace at sport weight blocks to a substantial fabric that holds up to wear.

Sport-weight is one of the least-stocked weights at major yarn shops; substituting a lightly-held DK at the same needle size often works.

Swatching at this weight

Sport's gauge sits at a noticeable boundary — at the same needle size, two different sport yarns can produce visibly different fabrics. Always swatch.

If a pattern calls for sport and you only have DK, swatch on the next-smaller needle and check both stitch and row gauge.
