How to make the Granny Square Bucket Hat Bigger
To make this hat fit perfectly, measure your head circumference and divide by 4. This gives you the width and height each granny square should be (minus 1 inch for the border).
For the standard adult medium shown here you will require
- 4 squares
- Each square = 5.5″ x 5.5″
- Finished hat circumference = 22 inches
- Crown diameter = 7 inches
Use this chart to adjust your granny square size and crown diameter for a perfect fit.
All measurements follow the formula: Head circumference ÷ 3.14 = crown diameter
Adult Small 21″ head • 6.7″ crown • 5.25″ square (Width / Height)
Adult Medium 22″ head • 7″ crown • 5.5″ square (Width / Height)
Adult Large 23″ head • 7.3″ crown • 5.75″ square (Width / Height)
Choosing Colours & Yarn
One of the best things about this easy crochet bucket hat pattern is how creative you can be.
Every hat becomes a one‑of‑a‑kind piece perfect for festivals, markets, and summer outfits.
Recommended materials:
- 4.00mm hook
- Double knit (DK) yarn for the squares
- Aran weight yarn for the main hat (adds structure to the brim)
- Gauge: 3 sc = 1″, 3 rows = 1″ (Note: I crochet loosely — adjust hook size if needed.)
Granny Square Bucket Hat Pattern
Make 4 Granny Squares
Each square is worked in 5 rounds. Pattern is written in US terms.
Notes:
- No magic ring needed — start with ch 4 and work into the first chain.
- Corners = (3 dc, ch 3, 3 dc)
- No chain spaces along the sides
- Each round increases by one 3‑dc shell per side
- Ch 3 counts as first dc
Round Instructions
Rnd 1: Ch 3, 2 dc in first chain. (Ch 3, 3 dc) three times. Join to top of ch‑3. Fasten off.
Rnd 2: Join new colour in any corner. Ch 3, 2 dc, ch 3, 3 dc in same corner. Repeat (3 dc, ch 3, 3 dc) in each corner. Join.
Rnd 3: Join next colour in any corner. Work corner (3 dc, ch 3, 3 dc). Work 3 dc in the space between corner shells. Repeat around. Join.
Rnd 4: Join next colour. Work corner (3 dc, ch 3, 3 dc). Work 3 dc in each side space. Repeat around. Join.
Rnd 5: Repeat the same structure, increasing one 3‑dc shell per side.
Rnd 6 (Border): Join main hat colour. Work sc around, placing 3 sc in each corner. Fasten off.
Assembling the Granny Squares
Lay out your 4 squares in your preferred colour order.
To join: Hold wrong sides together and slip stitch from corner to corner. This creates a structured, patchwork look.
Alternative: Sew squares together for a softer, less structured hatband.
Do not join the final side yet, this will be closed after attaching the crown.
Crochet the Crown (Top of Hat)
Using Main colour Aran yarn and a 4.00mm hook.
Do not join rounds work continuously.
Rnd 1: Work 7 sc into the first chain. (7 sts)
Rnd 2: Work 2 sc in each stitch around. (14 sts)
Rnd 3: Sc in the first stitch, 2 sc in the next stitch repeat from * to * around. (21 sts)
Rnd 4: *Sc in the next 2 stitches, 2 sc in the next stitch,* repeat *to* around. (28 sts)
Rnd 5: *Sc in the next 3 stitches, 2 sc in the next stitch,* repeat *to* around. (35 sts)
Rnd 6: *Sc in the next 4 stitches, 2 sc in the next stitch,* repeat *to* around. (42 sts)
Rnd 7: *Sc in the next 5 stitches, 2 sc in the next stitch,* repeat *to* around. (49 sts)
Rnd 8: *Sc in the next 6 stitches, 2 sc in the next stitch,* repeat *to* around. (56 sts)
Rnd 9: *Sc in the next 7 stitches, 2 sc in the next stitch,* repeat *to* around. (63 sts)
Rnd 10: Sc in each stitch around. (63 sts) Fasten off.
Your crown should measure 7 inches across circle diameter for an adult medium.
Attach Crown to Granny Square Band
Pin the squares evenly around the crown. Slip stitch the crown and squares together using the main colour.
Now close the final side seam of the squares.
Brim Rounds
Rnd 1: Working in front loops only, sc evenly around the entire lower edge of the joined granny squares. (Stitch count will vary depending on your tension.)
Rnd 2: Sc in the first 9 stitches, 2 sc in the next stitch — repeat from * to * around. (Stitch count will increase evenly.)
Rnd 3: Sc in the first 10 stitches, 2 sc in the next stitch — repeat from * to * around.
Rnd 4: Sc in the first 11 stitches, 2 sc in the next stitch — repeat from * to * around.
Rnd 5: Sc in each stitch around. Fasten off and weave in ends.

What yarn is best for a granny square bucket hat?
Use DK yarn for the granny squares and Aran weight yarn for the crown and brim. This keeps the squares light but gives the hat structure.
Is this a beginner‑friendly crochet pattern?
Yes! The pattern uses simple stitches, clear increases, and step‑by‑step instructions suitable for confident beginners.
How many granny squares do I need for a bucket hat?
You need four granny squares to create the hatband for a standard adult size. This forms the colourful patchwork section of the hat.
How do I make the brim sturdy?
Using Aran yarn for the brim helps it hold shape. Working the first brim round in front loops only also creates a clean edge and better structure.
