Simple Crochet Scarf Pattern: Adjustable Half Double Crochet

A simple crochet scarf can be made with one repeated half-double-crochet row. Work across the short width, keep the stitch count unchanged and add rows until you reach your chosen length. Measure a finished sample first: the same number of chains can make different widths in different yarns.

This free web guide uses US crochet terms and an adjustable construction. It is an original set of instructions, not a physically tested fixed-size pattern. The measurements and gauge calculations below are planning examples; your yarn, tension and finishing determine the actual result.

Materials and stitch terms

• A smooth yarn that feels comfortable against your neck and has care instructions suited to everyday use.
• A crochet hook near the yarn label’s suggested size, adjusted after sampling.
• Two stitch markers, a ruler or tape measure, scissors and a blunt yarn needle.

ch means chain; hdc means half double crochet; st means stitch. To make hdc: yarn over, insert the hook in the specified stitch, yarn over and draw up a loop, then yarn over and pull through all three loops. See our half double crochet lesson if this movement is new.

What dimensions should a crochet scarf be?

Choose dimensions by how you intend to wear the scarf. As a design starting point for an adult straight scarf, try roughly 6–8 inches wide and 60–70 inches long (about 15–20 cm by 152–178 cm), then adjust for the wearer and intended wrap. These are suggested targets, not a standard size chart.

Crochet scarf width and length guide (inches and cm)

Use these common starting ranges, then measure on the wearer before you finish:

Quick rule: a comfortable adult scarf is roughly as long as the wearer is tall, minus about 10 in (25 cm). Fringe adds to the total length.

Measure a scarf you already like or use a fabric strip to try the length. Decide whether your target includes fringe. A narrow scarf may drape easily while a wider one provides more coverage; the yarn and stitch density affect both.

Make a small gauge sample

1. Chain 14.
2. Row 1: hdc in the third chain from the hook and in every remaining chain. You have 12 hdc. The two skipped chains do not count as a stitch in this version.
3. Row 2: ch 2, turn. Hdc in the first stitch and in every stitch across. You still have 12 hdc. The turning chain does not count as a stitch.
4. Repeat Row 2 until the sample has enough rows to measure and fold comfortably.

Mark the first and last actual hdc of each row. Do not add a stitch into the turning chain. Finish the sample according to the yarn care label and let it dry before measuring. If it feels stiff or scratchy, change the yarn or hook and sample again.

Calculate the scarf width before starting

Measure stitches over a central section of your sample, excluding the edges where possible. Divide the stitch count by the measured width to get stitches per inch or centimeter. Multiply that figure by the target width and round to a whole stitch.

Example only: if you measure 12 hdc over 4 inches, your gauge is 3 stitches per inch. A 7-inch width would start with 21 hdc. For the setup used here, chain the chosen hdc count plus 2, so this example begins with 23 chains. If your gauge differs, the chain count must differ too.

Work the scarf, step by step

1. Foundation: chain your chosen stitch count plus 2, keeping the chain relaxed.
2. Row 1: hdc in the third chain from the hook and in every chain across. Count the hdc and record the total.
3. Row 2: ch 2, turn. Hdc in the first stitch and every stitch across. The turning chain is not a stitch. Check that the total matches Row 1.
4. Following rows: repeat Row 2. Keep working under both top loops unless you intentionally choose a different texture and resample it.
5. Length: measure the scarf laid flat without stretching. Stop when the body reaches your chosen target.
6. Finish: cut a tail long enough to weave in, pull it through the final loop and secure it with the yarn needle through several stitches, changing direction before trimming.

Finish the scarf following the yarn label. A border is optional. If the width gradually changes, correct the lost or added stitches before covering the edge. Our crochet curling guide helps distinguish a tight foundation from count errors.

How much yarn will the scarf need?

A fixed ball count would be misleading without a specified yarn and measured gauge. Weigh a finished sample and calculate its area. Multiply its grams per unit of area by the scarf’s planned area, then allow extra for tails, fringe and a practical reserve. Keep the sample’s fabric and gauge consistent with the actual scarf.

Check the label’s length per ball as well as weight. Two balls of equal weight may contain different lengths of yarn. Buy enough compatible yarn before starting, and check dye-lot information when a consistent color matters.

What is a good length for fringe on a scarf?

Choose fringe to suit the scarf rather than a universal rule. A finished length of about 3–5 inches (8–13 cm) is one adult design starting point. Try one tassel first. For a folded attachment, each strand needs a little more than twice the desired finished length to allow for the attachment and trimming.

Attach small groups evenly at the short ends without pulling the edge. Trim only after the scarf has received its planned finishing. Remember that fringe increases the overall end-to-end length.

Common questions

How many chains do I need for a scarf?

Use your gauge and target width. With this hdc setup, chain the desired number of stitches plus 2. The added chains are setup only; they do not count as hdc.

Can I turn this into an infinity scarf?

You can seam the short ends into a loop. Decide the loop circumference separately from a straight scarf’s length and test the intended wrap with a fabric strip before seaming. There is no one circumference that fits every wearer and wrap style.

Is half double crochet reversible?

Turned hdc rows can look attractive on both sides, though the faces may not be identical. Compare with moss stitch in our reversible crochet stitch guide.
