A first crochet scarf can be a straightforward rectangle: choose a comfortable width, keep the stitch count steady and stop at a length you will actually wear. A gauge sample makes that rectangle more predictable, even when you use a different yarn from the one shown in a tutorial.
Stitch terminology: This guide uses US names. US single crochet is UK double crochet; US half double is UK half treble; US double is UK treble. See the full US/UK reference.
Choose the size before the chain
Measure a scarf you like, or fold a strip of fabric to a comfortable width. As a planning example, 20 × 150 cm is about 8 × 59 inches. That is an example adult size, not a universal requirement. A short scarf worn inside a jacket and a long wrapping scarf need different lengths.
Decide whether you want fringe before measuring the body. Fringe adds length beyond the crocheted rectangle and needs its own yarn allowance.
Make a sample you enjoy touching
Use a smooth yarn and a hook that gives a comfortable fabric. Work a single-crochet sample larger than 10 cm in each direction, then care for it as the yarn label directs. Measure an interior section without stretching the fabric.
Check the feel against the neck as well as the count. A fabric can have a convenient gauge but still feel too stiff, heavy or scratchy for a scarf.
Calculate the starting width
If your sample measures eighteen stitches per 10 cm, a 20 cm width needs an estimated thirty-six stitches. For the simple single-crochet version below, chain thirty-seven. If your gauge differs, use your own count rather than copying thirty-seven automatically.
| Sample gauge | Target width | Worked stitches | Starting chains |
|---|---|---|---|
| 18 stitches / 10 cm | 20 cm | 36 | 37 |
| 16 stitches / 10 cm | 20 cm | 32 | 33 |
Work the rectangle
Single crochet in the second chain from the hook and in every remaining chain. Chain one and turn. The turning chain does not count. Work one single crochet in each actual stitch, beginning with the first and ending with the last.
Repeat that row until the scarf reaches your chosen body length. Mark the first and last stitches and check the count regularly. Finish a row before measuring or deciding to stop, so the top edge remains complete.
Estimate yarn from the fabric
For a rough example, a finished 10 × 10 cm sample weighing 8 g contains 8 g per 100 cm². A 20 × 150 cm body has thirty times that area, suggesting about 240 g in the same fabric before fringe, finishing and any allowance.
This is an estimate, not a shopping guarantee. A small sample, scale precision, different tension and changes to the design affect the result. Compare with the yarn requirement of a similar pattern and buy whole balls from compatible dye lots where colour matching matters.
Finish before adding decoration
Fasten off, weave the tails through suitable stitches and care for the scarf according to the yarn label. Lay it flat and inspect both edges. Add fringe only after confirming the body length and considering whether you want the extra weight and movement.
Keep the final stitch count, row count if recorded, yarn and dimensions with the project. That makes a second scarf easier to customise than starting again from an unexplained chain number.
