In this post
A beanie is the first wearable most people crochet, and the first thing that teaches them why gauge matters: a hat two inches too big simply falls over someone's eyes.
This pattern is written top-down in half double crochet, with a ribbed brim added at the end. Work out your size from the chart and the rest is repetition.
Hat sizing: the two numbers
Head circumference around the forehead, and hat height from crown to brim. A crocheted hat should be made about 1–2 in (2.5–5 cm) smaller than the head so it stretches to grip.
| Size | Head | Make the hat | Height | Stitches per round |
|---|---|---|---|---|
| Newborn | 13–14 in | 12 in | 5½ in | 48 |
| Baby 3–6 m | 15–16 in | 14 in | 6 in | 56 |
| Toddler 1–3 y | 17–18 in | 16 in | 7 in | 64 |
| Child 3–10 y | 19–20 in | 18 in | 7½ in | 72 |
| Teen / small adult | 21–22 in | 20 in | 8 in | 80 |
| Adult | 22–23 in | 21 in | 8½ in | 84 |

The pattern
Written for the adult size (84 stitches). For another size, increase until you reach that size's stitch count, then stop increasing.
Gauge
14 hdc and 10 rounds = 4 in (10 cm).
Crown
Worked in continuous rounds. Mark the first stitch of each round.
- Rnd 1: 12 hdc in a magic ring. (12)
- Rnd 2: Inc in each st around. (24)
- Rnd 3: (Hdc 1, inc) 12 times. (36)
- Rnd 4: (Hdc 2, inc) 12 times. (48)
- Rnd 5: (Hdc 3, inc) 12 times. (60)
- Rnd 6: (Hdc 4, inc) 12 times. (72)
- Rnd 7: (Hdc 11, inc) 6 times. (78)
- Rnd 8: (Hdc 12, inc) 6 times. (84)
The flat circle should now measure about 6½ in (16.5 cm) across — roughly a third of the head measurement. Stop increasing here.
Body
- Rnds 9–26: Hdc in each st around. (84)
Keep going until the hat measures 7½ in from the crown — the ribbed brim will add the last inch. Try it on as you go.
Ribbed brim
Worked sideways onto the bottom edge, which gives real stretch.
- Set-up: Ch 9.
- Row 1: Sc in the 2nd ch from the hook and in each ch across (8), then sl st into the next 2 sts of the hat edge. Turn.
- Row 2: Skip the 2 sl sts, sc in back loops only across. Ch 1, turn. (8)
- Row 3: Sc in back loops only across, then sl st into the next 2 sts of the hat edge. Turn. (8)
- Repeat Rows 2–3 all the way around the hat.
Fasten off leaving a long tail, and whip stitch the first and last rows of the brim together.
Make it your own
- Pom-pom: wrap yarn 80 times around a 4 in card, tie the middle tightly, cut the loops and trim into a ball.
- Stripes: change colour every four rounds; see the colour-change method in our team scarf.
- Slouchy: add four more body rounds before the brim.
- Matching set: hat and scarf in the same two colours.
Common questions
How do I know how big to make a crochet hat?
Measure the head and make the hat 1–2 in smaller, so it stretches to fit. The flat crown circle should measure about a third of the head circumference before you stop increasing.
Why does my hat come out like a bowl?
You increased for too many rounds. Stop as soon as the flat circle reaches a third of the head measurement, then work straight.
Why is my hat cone-shaped?
The opposite problem: too few increase rounds, so the crown pulls in. Add an increase round and try again.
How much yarn for an adult beanie?
About 180 yd (165 m) of worsted — one 100 g ball with some left over.
Can I make it without the ribbed brim?
Yes — just work six more body rounds and finish with a round of slip stitches. The ribbed brim grips better, which matters in wind.
