Free Crochet Headband Pattern (3 Sizes)
This headband works up in about 90 minutes using 62–78 yards of worsted weight yarn and a 5.0 mm (US H-8) hook, depending on size. It is worked flat as a long strip in half double crochet, then twisted once at the centre and seamed into a ring, so the only shaping is in the seam. Sized by head circumference: 20 inches (child), 21.5 inches (adult small/medium) and 23 inches (adult large).
This is a first-project pattern that does not look like one. It uses a single stitch, has no shaping, and the only construction step is a seam — but the half twist at the centre gives it the sculpted look of something considerably more complicated.
It takes about ninety minutes and well under one skein.
Sizing
Measure around the head where the band will actually sit — usually just above the ears and across the middle of the forehead — then pick the row from this table.
| Size | Head circumference | Strip length | Approx. rows | Yardage |
|---|---|---|---|---|
| Child (3–8 yr) | 20 in / 51 cm | 19 in / 48 cm | ~62 | 62 yd |
| Adult S/M | 21.5 in / 55 cm | 20.5 in / 52 cm | ~67 | 70 yd |
| Adult L | 23 in / 58 cm | 22 in / 56 cm | ~72 | 78 yd |
The strip is deliberately made about 1 inch shorter than the head measurement. Half double crochet worked into the third loop has real stretch, and a band cut to the exact measurement rides up and slips off within an hour of wearing.
Row counts are approximate because they depend on your tension. Trust the tape measure over the row count.
Gauge, and why it matters here
13 hdc × 10 rows = 4 inches (10 cm) in half double crochet through the third loop, on a 5.0 mm hook.
Work a swatch at least 4 inches square and measure it flat and unstretched. It takes ten minutes and it decides whether the band fits.
Width is forgiving — a band that comes out 2.5 or 3 inches wide still looks right. Length is not, because it sets the circumference. If your row gauge is off, ignore the row counts above entirely and simply work until the strip measures the length in the table.
The third loop
Half double crochet has an extra horizontal bar sitting behind the usual two loops, at the back of the stitch. Working into that bar instead of the normal two loops produces a distinctly ribbed, elastic fabric — it looks like knitted ribbing and behaves like it.
If you find the third loop hard to see, work the first few rows through both loops as normal and come back to it. The pattern works either way; standard hdc simply gives a smoother, firmer band, in which case add half an inch to the strip length to make up for the lost stretch.
The twist
The half twist before seaming is the whole trick. Lay the finished strip flat with the right side up, bring the ends together, and rotate one end 180° so the right side of one end faces the wrong side of the other. Seam across.
The band now has a permanent sculpted turn at the join. Rotate it round so that turn sits at the centre front.
Seam it without the twist and you have a plain band — quicker, flatter under a hat, and sized identically.

The pattern
- Setup Ch 11. This foundation chain sets the width of the band, not its length — the band is worked lengthwise from here. Keep the chain loose; a tight foundation chain is the most common reason a first row feels impossible to work into.
- Row 1 Working into the back bump of each chain, hdc in the 2nd ch from hook and in each ch across. 10 hdc. Place a stitch marker in the front of the work to mark the RS.
- Row 2 Ch 1 (does not count as a stitch), turn. Hdc in each st across, working into the third loop of each hdc — the horizontal bar sitting behind the usual two loops. 10 hdc. This third-loop technique is what gives the band its ribbed, stretchy texture.
- Rows 3 to end Repeat Row 2 until the strip measures the length for your size, unstretched: 19 in / 48 cm (child), 20.5 in / 52 cm (adult S/M), or 22 in / 56 cm (adult L). That is roughly 62, 67 or 72 rows. The strip is made about 1 inch shorter than the head measurement because half double crochet worked this way stretches.
- Finishing 1 Fasten off leaving a 14 in (36 cm) tail for seaming. Do not cut it shorter — the seam runs the full width of the band and a short tail will not reach.
- Finishing 2 Lay the strip flat with the RS facing up. Bring the two short ends together, but before joining, give one end a single half twist so the RS of one end meets the WS of the other. This half twist is what creates the sculpted centre knot; without it you get a plain loop.
- Finishing 3 Thread the tail onto a yarn needle and seam the two ends together with a whip stitch, working through both loops of each stitch across all 10 sts. Keep the tension even with the fabric — pulled tight, the seam puckers and shows.
- Finishing 4 Weave the tail into the seam allowance in two directions, then trim. Weave in the starting tail the same way. Rotate the band so the twist sits at the centre front.
Notes
- Yardage measured by weighing the finished band: 62 yd (child), 70 yd (adult S/M), 78 yd (adult L). One 170 g / 364 yd skein of worsted acrylic makes four adult headbands with yarn left over.
- Check gauge before committing. At 13 hdc x 10 rows per 4 inches the band is 2.75 in wide. If your swatch is wider, go down to a 4.5 mm hook; narrower, go up to 5.5 mm. Width is more forgiving than length here, but length determines whether it fits.
- Working into the third loop is optional. Standard hdc through both loops gives a smoother, less stretchy fabric — if you use it, make the strip 0.5 in longer, because it will not give as much.
- For a child under three, seam the ends with a doubled length of yarn and weave the tails in especially thoroughly. Nothing on this band should be able to work loose.
- Cotton produces a firmer band with almost no stretch — subtract nothing from the length and measure the wearer directly, because cotton will not forgive a short strip.
Common questions
What size crochet hook for a headband?
A 5.0 mm (US H-8) hook with worsted weight yarn, which is what this pattern is written and measured at. If your gauge swatch comes out wider than 13 hdc per 4 inches, drop to 4.5 mm; if narrower, go up to 5.5 mm. Changing hook size changes yardage too — going up one size adds roughly 10% to the yarn used.
How much yarn does a crochet headband use?
Between 62 and 78 yards of worsted weight, depending on size — measured by weighing the finished bands rather than estimated. That means a single 364-yard skein makes four adult headbands. Yardage rises if you crochet loosely or substitute a chunkier yarn.
How do I size a crochet headband?
Measure around the head where the band will sit, then make the strip about 1 inch shorter than that measurement. Half double crochet worked into the third loop stretches, and a band made to the exact head measurement will slide off. This pattern gives 19, 20.5 and 22 inch strips for 20, 21.5 and 23 inch heads.
Why does my headband curl at the edges?
Half double crochet curls less than double crochet but it can still cup slightly if your tension is tight. Blocking fixes it: for acrylic, steam block the finished band pinned flat; for cotton or wool, spray or wet block. If it curls badly, your gauge is probably tighter than stated — try a larger hook.
Can I make this headband without the twist?
Yes. Seam the two ends together without the half twist and you get a plain band, which is quicker and sits flatter under a hat. The twist is purely decorative and adds no length, so the sizing is identical either way.
