How to Knit a Hat for Beginners: Easy Step-by-Step Pattern

A hat is the ideal knitting project for beginners: it's small, you usually need just one ball of yarn, and after two or three evenings you're already wearing something you knitted yourself. In this guide, we show you how to knit a simple beanie with a ribbed brim – in the round on a circular needle, with no seams at all. You'll also learn which yarn works well for hats, how much yarn you need, and how to adjust your cast-on to your head circumference.

What you need for your hat

• Yarn: 1 ball of 100 g, for example our Virgin Wool Ronan, 160 m / 100 g. For a hat with a folded brim or a pom-pom, plan on a second ball.
• Circular needle in needle size 5.5 mm, 40 cm long
• Double-pointed needles in 5.5 mm for the crown decreases – or an 80 cm circular needle for the magic loop technique
• 8 stitch markers, one of them in a different color to mark the beginning of the round
• Tapestry needle with a blunt tip, scissors and a tape measure

Which yarn is best for a hat?

A good hat yarn is warm, stretchy enough for the hat to fit snugly, and feels soft against your forehead. For your first hat, we recommend a medium to thick yarn with a yardage of 120–180 m per 100 g and needle size 5–8 mm: the stitches are easy to see, and the hat grows quickly.

• Wool and virgin wool are elastic, hold their shape and keep you warm even on wet, cold days.
• Alpaca is especially soft and warm, and even a small share of alpaca in the yarn makes a hat cozier.
• Merino wool is very fine. Many people find merino hats comfortable even on sensitive skin.
• Blended yarns with acrylic are lightweight, keep their shape and make the hat more affordable.

Our yarns for hats

Virgin Wool Ronan, 160 m / 100 g – 78 % virgin wool, 22 % polyamide, needle size 5–6 mm, 18 colors. Most shades are plied with white, which gives the hat a lively, marled look. 1 ball is enough for an adult hat. The pattern below is knitted with this yarn.

Pure Virgin Wool Sabine, 175 m / 100 g – 100 % virgin wool, needle size 4.5–5.5 mm. A little firmer than other wools, which makes it ideal for crisp ribbing and cable patterns. 1 ball is enough for a hat.

Chunky Yarn Crush with Alpaca, 180 m / 100 g – 15 % alpaca, 15 % wool, 70 % acrylic, needle size 5–6 mm, 5 colors. Lightweight, solid-colored and a good choice for your first hat. Plan on 1–2 balls, depending on the size.

Chunky Wool Bella with Baby Alpaca, 120 m / 100 g – 30 % baby alpaca, 45 % wool, 25 % acrylic, needle size 7–8 mm. Our thickest yarn: if you want to knit a chunky hat, this is the fastest way to finish it. 1–2 balls.

Merino Wool Bonny, 350 m / 100 g – 93 % merino wool, needle size 3–3.5 mm. For fine, lightweight merino hats. You'll knit more stitches, but 1 ball is still enough.

You'll find more yarns in our Chunky Yarn, Alpaca Wool and Merino Wool categories, as well as in our selection for hats.

How much yarn do I need for a hat?

That depends mainly on the yarn weight. These guidelines are for an adult hat without a folded brim:

For a hat with a folded brim, you'll need about a third more. For a pom-pom with a diameter of 7 cm, allow an extra 15–20 g. You'll find the exact guidelines for each yarn in the product description under "Yarn requirements".

Gauge swatch and cast-on by head circumference

To make sure the hat fits, start with a gauge swatch: cast on about 20 stitches, knit 10–12 cm in stockinette stitch and count how many stitches there are in 10 cm. Then calculate:

Head circumference in cm × 0.9 × stitches per cm = number of stitches to cast on

The factor of 0.9 makes the hat slightly smaller than your head so it doesn't slip. Round the result to a number divisible by 8 – that way the k2, p2 ribbing and the decreases work out evenly. Example: 56 cm × 0.9 × 1.6 stitches = 80.6, so 80 stitches. We explain in detail how to knit, measure and convert a gauge swatch in our guide How to Knit a Gauge Swatch Correctly.

Pattern: knitting a hat step by step

Size: adult, head circumference 54–58 cm
Gauge: 16 stitches and 22 rounds in stockinette stitch = 10 × 10 cm on needle size 5.5 mm
Abbreviations: st(s) = stitch(es), k = knit, p = purl, tog = together

1. Cast on and join in the round

Using the circular needle, cast on 80 sts with the long-tail cast-on. Arrange the stitches on the needle so that the cast-on edge faces inward all the way around and isn't twisted. Place the contrasting stitch marker for the beginning of the round and join in the round by knitting the first stitch.

2. Knit the ribbed brim

Work in ribbing *k2, p2* to the end of the round. Repeat this round until the brim measures 6 cm. For a hat with a folded brim, knit the ribbing to 12 cm.

3. Knit in stockinette stitch

Now knit every stitch of every round until the hat measures 15 cm from the cast-on edge (with a folded brim: 21 cm). For a relaxed, slouchy women's hat, knit 3–4 cm more.

4. Crown decreases

In the next round, place a stitch marker after every 10th stitch. This gives you 8 sections of 10 stitches each. If you have a different stitch count, divide it into 8 equal sections in the same way.

Decrease round: *knit to 2 sts before the next marker, k2tog*, repeat 8 times. You now have 72 sts.

Alternate one decrease round with one plain round until 40 sts remain on the needle. From then on, work every round as a decrease round until 8 sts remain. Once the stitches no longer fit comfortably around the circular needle, switch to double-pointed needles or the magic loop technique.

5. Finishing

Cut the yarn, leaving a tail of about 20 cm, thread it onto the tapestry needle and draw it through the remaining 8 stitches. Pull the yarn tight, bring it to the inside and weave it in securely. Weave in the cast-on tail at the brim as well.

Finally, hand wash the hat at no more than 30 °C, gently press out the water without wringing, and let it dry flat. This gives the stitches their final shape. For more care tips, see our guide How to Wash Wool.

Variations: folded-brim hat, pom-pom hat and kids' hat

• Hat with a folded brim: knit the ribbing to 12 cm and the stockinette section up to 21 cm. The double-layered brim keeps your ears especially warm.
• Pom-pom hat: make a pom-pom from leftover yarn with a pom-pom maker or two cardboard rings, and tie it firmly to the inside of the crown with the long yarn ends.
• Kids' hat and baby hat: take the number of stitches to cast on from the table above and knit the stockinette section shorter: about 9 cm from the cast-on edge for babies and 12 cm for children. You'll find soft yarns for babies in our Baby Yarn category.
• Chunky hat: with Chunky Wool Bella and needle size 7–8 mm, cast on 64 sts for a 56 cm head circumference and knit the same way.

Knitting a hat without a circular needle

Only have two straight needles? Then knit the hat flat in rows and seam it at the end. Cast on 2 extra edge stitches, so 82 sts. On the wrong-side rows, work the stitches as they appear. Work the decreases on right-side rows only. Finally, close the seam with mattress stitch – that way it's barely visible from the outside.

Frequently asked questions about knitting a hat

How long does it take to knit a hat?
With chunky yarn, a hat can be done in a single evening. As a beginner, plan on two to three evenings.

What needle size do I need for a hat?
Use the needle size given in the yarn's product description. If you want a snugger brim, knit it on needles half a size smaller.

Is a wool hat itchy?
That depends on the fiber. Merino wool and baby alpaca are especially fine. If you have sensitive skin, choose a yarn with a high percentage of them.

Can I crochet the hat instead?
Yes, all the yarns mentioned here are also great for crochet.

To go with your hat, knit a matching scarf with our guide How to Knit a Scarf for Beginners. To find out which yarns go with which needles, see our guide Which Yarn for Needle Sizes 5, 6 and 8?
