This chunky crochet infinity scarf pattern is designed for a satisfying weekend project. You make one long rectangle in half double crochet, check the drape, then seam the short ends to create a loop.
A measurement-based pattern is more reliable than a fixed chain count because bulky yarns vary widely. The finished scarf can be worn as one long loop or wrapped twice around the neck.

Before you begin
Make a 5-inch swatch and wash it the way you will wash the scarf. A comfortable scarf should bend easily instead of standing stiff. Use a larger hook if the fabric feels dense.
Step-by-step instructions
Choose the width
Chain until the foundation measures 8–10 inches without stretching. For many bulky yarns this is about 18–24 chains, but use the measurement rather than copying the count.
Row 1
Hdc in the second chain from the hook and in every chain across. Chain 1 and turn. The turning chain does not count as a stitch.
Build the texture
Hdc BLO in each stitch across, chain 1, and turn. Place a marker in the first and last stitch, moving them up every row.
Crochet to length
Repeat the textured row until the rectangle measures 55–62 inches. Wrap the unfinished strip around your neck to check whether it can loop twice comfortably. Add or remove rows before seaming.
Join the ends
Place the short ends together with right sides facing. Slip stitch through both layers, matching one row end to one row end. Keep the seam loose so it stretches like the fabric.
Finish the scarf
Fasten off and weave the tail back and forth through several rows. Turn the scarf right side out and gently block the seam area.
Troubleshooting and useful tips
- Count stitches every few rows so the scarf does not gradually narrow.
- Buy all skeins from the same dye lot when possible.
- A foundation chain that is too tight makes one edge shorter; use a larger hook for the chain if needed.
- Stop and compare length after washing the swatch because bulky fibers can grow.
Ways to customize it
- For a smoother fabric, work through both loops instead of BLO.
- Add stripes by changing color at a row edge and carrying no long floats.
- Make a single-loop cowl about 24–28 inches around, checking that it fits comfortably over the head.
Frequently asked questions
How long should an infinity scarf be?
About 55–62 inches suits many adults for a double wrap, but neck size, yarn thickness, and personal preference matter.
Can I use worsted yarn?
Yes. Use the hook recommended for the yarn and make more foundation chains and rows to reach the same measurements.
How do I prevent a bulky seam?
Use slip stitches or mattress stitch with relaxed tension and match each row end once.
