A bucket hat in granny stitch is the warm-weather accessory that makes practical sense.
The open cluster-and-chain pattern lets air circulate through the crown while still shading your face. Unlike solid double crochet bucket hats that can feel like wearing a sauna on your head, the mesh construction keeps you cool while providing sun protection.
The hat is worked from the crown down. The crown grows as a flat circle in granny stitch with increases spaced evenly around. The body works even. The brim flares outward with strategic increases placed at specific points around the circumference.
The entire hat uses about 80 grams of cotton yarn and can be made in a solid color or with alternating rounds for a two-tone effect.
Why You'll Love This Bucket Hat
The granny stitch is naturally open and breathable.
Each cluster of three double crochets is separated by a chain-1 space. Those spaces create ventilation. On a hot day, the difference between a solid hat and a mesh hat is immediately noticeable.
The construction is straightforward granny stitch logic.
Increase rounds for the crown. Even rounds for the body. Strategic increase rounds for the brim. If you understand how granny squares grow, you understand how this hat grows.
The sizing is adjustable at each stage. The crown determines the hat diameter. The body rounds determine the height. The brim rounds determine the projection. You can customize each independently.
The chain-3 at the start of each round counts as a double crochet. Pay attention to this, as it differs from some patterns where the turning chain doesn't count.
Materials Needed
- 80 grams / 140 yards of worsted weight (#4) cotton yarn
- 5.5 mm (I-9) crochet hook
- Scissors
- Tapestry needle
Favorite Cotton in Cream is the yarn shown. At about $4.99 per skein, one skein covers the hat. Cotton is preferred for its structure—the brim needs to hold its shape.
For a two-tone hat, use two contrasting colors and alternate rounds. Change colors at the slip stitch join for a clean transition. One skein of each color makes multiple hats.
Best Yarn Choices for a Mesh Bucket Hat
Cotton gives the brim structure. The granny stitch is open, so the brim needs enough body to project outward rather than droop. Cotton's natural stiffness supports the brim shape.
Cotton blends work well. Favorite Cotton (cotton-acrylic) combines structure with a softer hand. Lion Brand 24/7 Cotton gives the crispest stitch definition.
Acrylic will produce a softer, less structured brim. If using acrylic, the brim may need light starching or steam blocking to hold its shape. For more on choosing yarn for hats, see my beginner yarn guide.
Gauge, Size Guide & Must-Have Tools
Gauge: 8 rows of 4 clusters and spaces = 4 inches square.
Finished dimensions (adjustable):
- Overall width: about 13.2 inches
- Height: about 7.9 inches
- Fits head circumference: about 20–21.7 inches
For a larger hat, add an extra cluster to one or two of the single-cluster spaces in round 5. For a smaller hat, stop increasing the crown earlier.
Must-have tools:
- 5.5 mm hook: Standard worsted weight hook.
- Tapestry needle: For weaving ends.
Pattern Notes & Tips Before You Start
The crown increases follow granny circle logic. Round 1 has 3 clusters. Round 2 doubles to 6. Round 3 doubles to 12. Round 4 works even. Round 5 increases to 18. The hat size is determined at round 5.
The first cluster of each new round goes into the space right at the base of the turning chain. The last repeat of each round goes into the first space of that round.
The slip stitch at the end of each round goes into the top of the chain-3 from the start of that round. The chain-3 counts as a double crochet.
For a two-tone hat, change colors at the slip stitch join of each round. Pull the new color through on the final yarn-over. This creates clean color transitions.
Abbreviations Explained

- dc – double crochet: Yarn over, insert hook, pull up loop, (yarn over, pull through two loops) twice.
- rep – repeat: Work the instruction set again.
- sl st – slip stitch: Insert hook, yarn over, pull through stitch and loop.
Step-by-Step Granny Stitch Bucket Hat
Crown
Foundation: Make a magic ring or chain 4 and slip stitch to form a ring.
Round 1: Chain 3. Dc2 into the ring. (Ch 1, dc3 into ring) twice. Ch 1. Slip stitch to top of chain-3. (3 clusters)
Rounds 2–3: Chain 3. Dc2 into the space below. (Ch 1, dc3, ch 1, dc3 in next space) repeat. End with the last repeat in the first space. Slip stitch. (6 clusters, then 12 clusters)
Round 4: Chain 3. Dc2 into space below. (Ch 1, dc3 in next space) repeat around. Ch 1. Slip stitch. (12 clusters, even)
Round 5: Chain 3. Dc2 into space below. (Ch 1, dc3, ch 1, dc3 in next space, ch 1, dc3 in next space) repeat around. End with the last repeat in the first space. Slip stitch. (18 clusters)
For a medium hat, add an extra cluster to one single-cluster space. For large, add to two spaces.
Body
Rounds 6–13: Chain 3. Dc2 into space below. (Ch 1, dc3 in next space) repeat around. Ch 1. Slip stitch. (18 clusters)
For a shorter hat, work fewer rounds. For a taller hat, work more.
Brim
Round 14: Chain 3. Dc2 into space below. (Ch 1, dc3, ch 1, dc3 in next 2 spaces, ch 1, dc3 in next space) repeat around. Slip stitch. (30 clusters)
Rounds 15–17: Chain 3. Dc2 into space below. (Ch 1, dc3 in next space) repeat around. Ch 1. Slip stitch. (30 clusters)
Fasten off. Weave in ends.
Easy Variations & Custom Ideas
Two-tone: Alternate colors every round for a striped mesh effect.
Wider brim: Add additional increase and even rounds to the brim section.
Shorter body: Reduce body rounds for a shallower hat.
Ribbon band: Thread a ribbon through the last body round for a decorative touch.
Common Troubleshooting and Fixes
Crown is cupping: Too few increases. Check that you're following the increase rounds correctly. Round 3 should double from 6 to 12 clusters.
Brim won't stay out: Cotton provides the best structure. For acrylic hats, steam block the brim with light starch.
Clusters look uneven: Maintain consistent tension on the chain-1 spaces. Uneven chains create uneven clusters.
Hat is too small: Add an additional increase round before starting the body.
Final Thoughts
A mesh bucket hat is the intersection of practical and stylish.
It keeps the sun off while letting the breeze through. It looks intentional and handmade without being fussy. And the granny stitch texture gives it a vintage charm that solid-stitch bucket hats lack.
Make one in cream for summer and wear it everywhere.
