How many balls to buy
Buy by length, not by ball: a ball of Premier Basix Worsted in a solid shade holds 328m (print and multi shades often come in smaller balls; check the label) and a ball of Paintbox Simply Aran holds 184m.

Before you swap
US “worsted” (weight 4) sits between UK DK and aran; most worsted patterns work in a UK aran, but a lighter worsted can be closer to a heavy DK. Make a 10cm swatch in your swap yarn with the pattern’s hook or needles and compare it with the tension above. If your square is bigger, go down a size; if it’s smaller, go up. Swapping fibre changes the feel and the wash: acrylic for acrylic, cotton for cotton keeps a pattern behaving as written.

How we rank swaps: one combined score for closeness in metres per 100g, knitted tension on the ball band and fibre, with a small penalty for yarns with fewer than 10 shades in stock and for a chunky standing in for a worsted.
