Bucket Hat Crochet Pattern

This unisex, striped crochet bucket hat is quick and easy to crochet and is also available on the blog for free.

Supplies

  • Medium Weight (#4) yarn (more details on the yarn below).
  • 4.5 mm (US G+/7) hook for the Adult Large or any other hook size needed to meet gauge.
  • 3.75 mm (US F) hook for the Small Adult/Teen size or any other hook size needed to meet gauge.
  • Scissors: with the constant yarn switching, you’ll need a pair of scissors the whole time.
  • Tapestry needle: you’ll have quite a few ends to weave in.
  • Flexible measuring tape.

Yarn Options

Generally, I like crocheting bucket hats with 100% cotton yarns. But this time, I tried a couple of cotton-blend and acrylic options. And let me tell you! I am so glad I did. I love the result.

Yarn Option #1:

For the larger granny square bucket hat, I used a yarn called Cotton-Ease by Lion Brand. This yarn is a worsted weight (#4) with a fiber content of 60% Cotton / 40% Acrylic. This yarn has been discontinued, but Made With Love The Cotton One by the same brand is a perfect substitute.

Amount needed:

Color 1: Alabaster (light color) – You’ll need approximately 1.87 oz (53 g) or 99 yds (91 m).

Color 2: Indigo (dark color) – You’ll need approximately 2.39 oz (68 g), or 126 yds (115 m).

Yarn Option #2:

I used Jeans Yarn by Lion Brand for the smaller granny square bucket hat (Teen/Small Adult size). This yarn is a worsted weight (#4) with a fiber content of 100% Acrylic. It is so soft and makes a super cool denim-style bucket hat.

Amount needed:

Color 1: Classic (dark denim blue) – You’ll need approximately 1.63 oz (46 g), or 115 yds (105 m).

Color 2: Top Stitch – You’ll need approximately 1.36 oz (39 g), or 96 yds (88 m).

Stitches & Techniques

In addition to the crochet basics, such as chain (ch), half double crochet (hdc), double crochet (dc), and slip stitch), you’ll need these other skills:

  • Treble (tr): Yarn over twice, insert the hook in chain space, yarn over and pull up a loop (4 loops on hook), yarn over, and pull through 2 loops three times.
  • Puff stitch with three half double crochet stitches (3hdcps): (Yarn over, insert the hook in stitch, yarn over, pull up a loop) 3 times. Yarn over and pull through 7 loops to complete the stitch.
  • Puff stitch with four half double crochet stitches (4hdcps): (Yarn over, insert the hook in chain space, yarn over, pull up a loop) 4 times. Yarn over and pull through 7 loops to complete the stitch. 
  • To start a new round with the puff stitch, pick up a loop with the new yarn and extend that loop to the height of the puff stitch. Then, proceed per the pattern instructions. The first stitch will have one extra loop on the hook.

  • Color change: For this granny square bucket hat, you’ll work with at least two yarn colors. It’s nothing super complicated, but you’ll need to know the basics of changing yarn colors in a project.
  • Finishing skills: fasten off and weave in the yarn ends.

Notes

This granny square bucket hat pattern uses US crochet terminology.

Level of difficulty: Intermediate. You need to know how to follow written patterns using abbreviations in US terms.

Overall Pattern Highlights

  • This pattern works best when you use at least two different yarn colors. This means you’ll change the yarn in every round of the crown pentagon and side squares.
  • Color change in the brim is optional but also recommended.
  • The brim is worked in a spiral, continuous rounds, meaning you don’t join at the end of each round.
  • Use stitch markers throughout the pattern to easily track the stitches and rounds.
  • Due to the nature of this granny square bucket hat pattern, changing sizes is only possible when working with different hook sizes. Please take a look at the gauge section below for the details.

Measurements

The instructions are the same for the Small Adult/Teen (21″ to 22″ heads) and Large Adult (23″ to 24″ heads) sizes. However, you’ll need to use a different hook size and meet gauge for each of the two hat sizes.

  • The Small Adult/Teen hat’s circumference will be approximately 21” (53.5 cm) and 8” (20 cm) tall.
  • As for the Large Adult, it will be approximately 23” (58.5 CM) and 9” (23 cm) tall.

Gauge

Meeting gauge is crucial to have your finished granny square bucket hat in the correct size. Here are the measurements you should achieve:

  • With the 3.75 mm (US F) hook, if you’re making the Small Adult/Teen size: The first two rounds of the square (not the pentagon) = 2.5” (6.5 cm) in diameter, measured across. The finished square will be approximately 4” (10 cm) wide.
  • With the 4.5 mm (US G+/7) hook, if you’re making the Large Adult size: The first two rounds of the square (not the pentagon) = 2.75” (7 cm) in diameter, measured across. The finished square will be approximately 4.5” (10.5 cm) wide.

Abbreviations (US terms)

  • 4hdcps: 4-half-double-crochet-puff-stitch

Instructions

This granny square bucket hat pattern has two puff stitch variations. Before you start making the hat, see the “special stitches” section above for the written instructions on how to create the puff stitches.

Step 1: Crown 

Please work with your choices of yarn colors, changing it in every round for both the crown and the side squares. 

Important: Make sure you check size and gauge sections so you will know what to expect about sizes.

Make 1 pentagon for the crown. Start with a mc, ch 2 (doesn’t count as a st).

R1: 20 dc in the mc, sl st to join.

R2: (3hdcps, ch 1) around [20 3hdcps and 16 ch 1 sps]

R3: (4hdcps, ch 1) around [20 4hdcps and 16 ch 1 sps]

R4: ch 4, dc cluster in same sp as ch 4, dc cluster in each of next 3 ch 1 sps, *(dc cluster, ch 1, dc cluster) in next ch 1 sp, dc cluster in each of next 3 ch 1 sps, rep from the asterisk 3 more times, dc cluster in same sp as initial ch 4.

Step 2: Body of the hat 

Make 5 squares, one at a time, separately. Start with a mc, ch 2 (doesn’t count as a stitch). 

R1: 16 dc in the mc, sl st to join.

R2: (3hdcps, ch 1) around [16 3hdcps and 16 ch 1 sps]

R3: (4hdcps, ch 1) around [16 4hdcps and 16 ch 1 sps]

R4: ch 5, tr cluster in same sp as ch 4, dc cluster in each of next 3 ch 1 sps, *(tr cluster, ch 1, tr cluster) in next ch 1 sp, dc cluster in each of next 3 ch 1 sps, rep from the asterisk 2 more times, tr cluster in same sp as initial ch 4.

Tip: At round 3, the square may feel tight and like it’s going to bowl. That’s normal. It will straighten up when you finish round 4.

Step 3: Assemble the crown 

Assemble the crown (pentagon) and the squares to build up your granny square bucket hat with sc sts.  

  1. First, match one side of one of the squares with one side of the pentagon, the wrong side facing the wrong side. Keep the right side of the square facing you.
  2. Next, attach the yarn to both layers of the first stitch in one of the corners of the pentagon and the square.
  3. Then, sc in the next 15 stitches, sc in the next corner with a corner of a new square. 
  4. Repeat steps 1 to 3 for the remaining squares without cutting the yarn. Sl st to join. Do not cut the yarn.
indigo and white yarn

Step 4: Assemble the sides

Now, you will do the same with the five sides of the squares that form the “bucket” of your granny square bucket hat. 

You can continue from where you stopped with the uncut yarn.

  1. Single crochet in the next 15 stitches (grabbing both square stitch layers) to seam the first two squares together, and single crochet in the next corner. FO. Cut the yarn.
  2. Attach the yarn to the stitch close to the crown and repeat step 1 on the following 4 square sides, one at a time. 

Tip: At this point, you have a “bucket” that should be long enough to be right above the top of your ears. If you need your granny square bucket hat to be longer, add one or two extra hdc rounds of 80 sts in the next step before increasing the brim.

Step 5: Brim

Next, attach the yarn color you used to assemble the squares to crochet the first round. Then, alternate with the yarn color used for round 4 of the squares for the remaining rounds. 

Tip: When changing yarn colors on the brim, there’s no need to cut the yarn. Just drop it and pick it back up in the next round.

R1: hdc around doing hdc2tog in each of the two the square corner joints [80]

Continue to sc around in continuous rounds, without joining. 

R2: (sc inc, sc in next 15 sts) 5 times [85]

R3: (sc inc, sc in next 16 sts) 5 times [90]

R4: (sc inc, sc in next 17 sts) 5 times [95]

R5: (sc inc, sc in next 18 sts) 5 times [100]

R6: (sc inc, sc in next 19 sts) 5 times [105]

R7: (sc inc, sc in next 20 sts) 5 times [110]

R8-12: sc around [110] 

This is a good time to add more plain rounds to make your brim longer if you like. Or make it shorter by subtracting rounds. Your choice.

Granny Square Bucket Hat FAQs?

Are granny square bucket hats easy?

Yes. This hat is simple to crochet and will make a great first-time color change project. But if you’re new to sunburst crochet squares, ensure you are comfortable with some advanced techniques, such as puff stitches and color changes.

Can this hat be smaller?

It depends! If you are okay with doing some math, you can try it. Crochet a square using lighter yarn and/or a smaller crochet hook. Then, measure one side of the square and multiply by 5. The result should be equal or about 1 to 2 inches smaller than the head circumference.

What yarns are best for a granny square bucket hat?

Typically, lighter-weight cotton or cotton blends are best for hats worn in warmer seasons. But good-quality acrylic yarns can also be a great option. The denim hat pictured in this pattern was made with 100% acrylic yarn.

How many granny squares are needed for a bucket hat?

You will need one pentagon for the crown and five granny squares for the body of the hat. Once you have the pentagon and squares done, will then assemble the hat with single crochet stitches and crochet the brim.
