How to Crochet a Hat: Easy Beginner Pattern in All Sizes

Crocheting a hat is quicker than you think: you start at the top with a magic ring, increase evenly in every round until the circle is big enough, and then crochet straight down. In this tutorial, you’ll crochet a hat in half double crochet – with a size chart from baby to adult, the right yarn for hats, and ideas for the brim, a folded cuff, and a pom-pom.

Crocheting a hat: what you need

• Yarn: 1–2 balls, depending on size and yarn, for example Virgin Wool Ronan, 160 m / 100 g
• Crochet hook in 6 mm for medium-heavy yarn or 8 mm for chunky yarn
• Stitch marker to mark the beginning of the round
• Tapestry needle, scissors, and a tape measure
• For a pom-pom: a piece of sturdy cardboard

We explain the basic stitches – chain, slip stitch, single crochet, and half double crochet – plus the magic ring step by step in our guide Crochet for Beginners.

Which yarn is best for crocheting a hat?

A good yarn for hats keeps you warm, feels comfortable on your head, and holds its shape. Here’s what matters:

• Wool content: Virgin wool and alpaca are warm and stay elastic – the hat stays put without slipping.
• Soft on your forehead and ears: If you have sensitive skin, choose a yarn with baby alpaca. We explain why alpaca is so soft in our guide Alpaca Wool: Properties and Tips.
• Weight: Medium-heavy yarns with 150–180 m per 100 g and a 5.5–6.5 mm hook make an everyday hat. Chunky yarn with 120–130 m and a 7–9 mm hook makes a cozy winter hat that works up especially fast.
• Smooth, not fluffy: For your first hat, a smooth yarn is easier, because you can see the stitches clearly.

How much yarn do you need for a crocheted hat?

Crochet uses a bit more yarn than knitting. If you’re between two sizes, it’s better to plan on one extra ball – any leftovers can become a pom-pom.

Getting the size right: measuring head circumference

Measure the head circumference with a tape measure, holding it level across the forehead, just above the ears, and around the back of the head. The hat should be a little smaller than the head so it doesn’t slip. The chart shows you how big the circle at the top needs to be and how tall the finished hat will be:

To calculate it yourself: take the head circumference, subtract 2–3 cm, and divide by 3.14 – that’s the diameter of the circle. Measure the height with the hat lying flat, from the magic ring to the bottom edge.

Pattern: crocheting a hat step by step

Materials: Virgin Wool Ronan, 6 mm crochet hook, stitch marker
Sizes: baby to adult; see the chart above for measurements
Gauge: not needed – you crochet to measurements and try the hat on as you go
Abbreviations: ch = chain(s), sl st = slip stitch(es), sc = single crochet, hdc = half double crochet, st(s) = stitch(es), rnd(s) = round(s)

Each round begins with ch 2, which does not count as a stitch. Work the first hdc into the same stitch as the sl st from the end of the previous round. Close the round with 1 sl st into the first hdc. Mark the first hdc of each round with a stitch marker so you can find it easily.

1. The circle: increasing from the top

Start with a magic ring and crochet the rounds as shown in the chart. An increase means: 2 hdc in the same stitch.

After each round, lay the circle flat and measure its diameter. As soon as it reaches the measurement for your size, stop increasing. With Ronan and a 6 mm hook, that’s usually after round 7 or 8 for adults, after round 6 or 7 for children, and after round 5 for babies. If the circle falls between two rounds, go with the smaller one – crocheted hats give a little as you wear them.

Circle not lying flat? If it ruffles, add one round without increases and then continue with the next round in the chart. If it cups like a bowl, you’re crocheting very tightly – switch to a hook 0.5 mm larger.

2. Crocheting straight down

From now on, work every round without increases: ch 2, 1 hdc in each st, 1 sl st into the first hdc. The hat now grows downward. Keep going until it’s about 3 cm shorter than the height in the chart – the brim adds those 3 cm. Try the hat on every now and then: the brim should cover your ears in the end.

With rounds joined by a sl st, the seam where rounds meet drifts slightly to one side. It’s hardly noticeable if you wear the hat with the seam at the back.

3. Crocheting the brim

Choose one of these two brims:

• Single crochet brim: 3–4 rnds of sc: ch 1 (does not count), 1 sc in each st, 1 sl st into the first sc. The brim lies flat and fits a bit more snugly if you crochet it with a hook 0.5–1 mm smaller.
• Ribbed brim in post stitches: This looks like knitted ribbing. Ch 2 (does not count), then alternate 1 front post double crochet and 1 back post double crochet around the stitches of the previous round. In the next 3 rnds, work each post stitch as it appears: front post over front post, back post over back post.

Front post double crochet: Yarn over, insert the hook from front to back to the right of the post of the stitch in the previous round, and bring it back to the front on the left, so the hook sits behind the post. Yarn over, pull up a loop, and finish the double crochet as usual. Back post double crochet: the same, but insert the hook around the post from the back, so the hook sits in front of the post.

4. Finishing

Cut the yarn, pull it through the last loop, and weave in all ends on the inside. Before that, pull the starting tail at the magic ring tight once more. Hand wash the hat at a maximum of 30 °C and let it dry flat – more on this in our guide How to Wash Wool.

Variations: winter hat, folded cuff, and pom-pom

• Crocheting a winter hat: With Chunky Wool Bella and an 8 mm hook, your hat will be thick and cozy. Because the stitches are bigger, you’ll reach the diameter in fewer rounds – just measure as you go.
• With a folded cuff: Crochet the hat 5–6 cm taller than in the chart and fold the brim up to the outside. The ribbed brim in post stitches works especially well for this.
• Pom-pom: Wrap the yarn 80 to 100 times around a piece of cardboard 8–10 cm wide. Carefully slide the bundle off, tie it tightly in the middle, cut through the loops on both sides, and trim the pom-pom into a round shape. Use the tying strands to sew it to the top of the hat.
• Slouchy beanie: Crochet the hat 4–6 cm taller so it drapes loosely at the back.
• Stripes: Using Virgin Wool Ronan in two or three colors, change color every 2–3 rounds, always at the sl st at the end of the round.

Common mistakes when crocheting a hat

• Hat too big: You kept increasing for too long. Rip back to the second-to-last increase round and continue straight from there.
• Hat too tight: Rip back to the circle and add one more increase round.
• Hole in the center: The magic ring wasn’t pulled tight enough. Pull on the starting tail and weave it in carefully.
• Stitch count is off: Usually the sl st or one of the 2 starting chains was counted as a stitch. Count your stitches at the end of every round.
• Brim stretches out: Crochet the brim with a smaller hook, or choose the ribbed brim in post stitches.

Frequently asked questions about crocheting hats

How many stitches do I need for a crocheted hat?
With this method, there’s no math involved: you increase until the circle reaches the diameter in the chart. With a 6 mm hook and medium-heavy yarn, that’s usually 70–80 half double crochet stitches for adults.

How much yarn do you need for a crocheted hat?
For adults, about 110–150 m of medium-heavy yarn – usually one 100 g ball. For a folded cuff or a pom-pom, plan on a second ball.

Which crochet hook should I use for a hat?
The size given on the ball band or the product page: 5.5–6.5 mm for medium-heavy yarn, 7–9 mm for chunky yarn.

How long does it take to crochet a hat?
With chunky yarn, you can finish a hat in one evening; with medium-heavy yarn, in one or two evenings.

Crocheted or knitted – which is better for a hat?
Crocheted hats are denser and a little firmer; knitted hats are stretchier. If you prefer knitting, our tutorial Knitting a Hat for Beginners shows you how to make a beanie with a ribbed brim. You’ll find the basics in Learn to Knit for Beginners.
