How much wool to knit a scarf?

How many balls of wool for a knitted DK scarf?

DROPS 52-23 allocates 200 g of Karisma, or 400 m, for a 20 × 160 cm scarf. Weston’s scarf is 21–23 × 180 cm and allocates 300 g: 600 m in Karisma or 630 m in Merino Extra Fine. Weston’s two yarn choices are one design, not two separate examples.

The comparison balls contain 295 m (Special DK), 276 m (Simply DK) or 268 m (Bambino DK), all per 100 g. Round the total length up for each colour; two balls bought do not mean two entire balls used.

Needles and stitch change the fabric

The smaller scarf uses 3.5 mm needles and checks 25 stitches per 10 cm in its named pattern. Weston uses 4 mm needles and gives 21 stitches × 28 rows in stocking stitch. Match the check your pattern actually asks for rather than a generic DK number.

Both the finished width and the stitch matter. A wider scarf, deeper texture or longer fringe can need more metres. The source allocation belongs to the complete stated design; do not silently subtract finishing or add a second reserve already included by your pattern.

Wool or washable acrylic?

Karisma and Merino Extra Fine are wool. The three 100 g comparisons are acrylic, which changes elasticity, moisture behaviour and care. Equal metres buy equal length, not an identical scarf. Make a tension square and check whether you like its drape before ordering all the colours.

For a stripe, calculate each shade’s share separately. Tiny stripe allocations can round up to several purchased balls even when the total metres would fit in fewer single-colour balls.

Where these numbers come from

Two published knitting designs from DROPS were checked on 12 October 2026. We converted each scarf-only gram allocation using the manufacturer’s actual metres per ball, then rounded by the three UK comparison yarns. Hat, cardigan and sock quantities in the source sets are excluded. We have not made or weighed these scarves.

This is a separate knitting page because its source designs and quantities differ from our crochet scarf sample. These are not matched experiments, so they do not establish that one craft always uses more wool.
