A cotton beanie is the hat for days that are cool but not cold: light on the head, smooth against the skin and thin enough to fold into a pocket. This pattern uses DK weight (3) cotton, a shallow ribbed brim and a plain stockinette body worked in the round. It comes in two adult sizes, and every round of the crown is written out with its stitch count.
Why cotton behaves differently from wool
Wool fibers are springy, so a wool hat stretches over the head and pulls back in. Cotton has very little stretch and almost no spring. That changes three things about how a cotton hat is planned:
- Less negative ease. The fabric will not stretch far, so this hat is sized closer to the head than a wool hat usually is.
- A firmer brim. The ribbing is worked on a needle two sizes smaller, because the stitch pattern has to supply the grip the fiber does not.
- A firm gauge. Cotton is heavier than wool of the same thickness, and loose cotton fabric tends to sag with wear.

A blend of cotton with a little wool or another elastic fiber is easier on the hands and holds its shape slightly better. The guide to the best yarn for knitted hats compares fibers in more detail.
What you need
- Yarn: DK weight (3) cotton or cotton blend, about 170 (190) yd, or 155 (174) m. These are estimates; buy a little extra. DK is number 3 in the standard yarn weight system.
- Needles: US 4 (3.5 mm) 16-inch circular for the brim; US 6 (4 mm) 16-inch circular and a set of US 6 (4 mm) double-pointed needles (DPNs) for the body and crown.
- Notions: a stitch marker, a tapestry needle, scissors and a tape measure.
Tip
Cotton can feel slippery on metal needles. Bamboo or wood needles hold the stitches a little more and make an even tension easier to keep.
Gauge
22 stitches and 30 rounds = 4 in (10 cm) in stockinette stitch on US 6 (4 mm) needles, measured after washing. That is 5.5 stitches per inch. Cotton can lengthen when washed, so knit and wash a gauge swatch before starting. If you count more than 22 stitches in 4 in, go up a needle size; if fewer, go down.
Finished sizes
| Size | Cast on | Hat circumference | Hat height | Fits head of about |
|---|---|---|---|---|
| Adult small / medium | 104 sts | About 19 in (48 cm) | About 8 in (20.5 cm) | 20.5 to 21.5 in (52 to 54.5 cm) |
| Adult medium / large | 112 sts | About 20.25 in (51.5 cm) | About 8.5 in (21.5 cm) | 22 to 23 in (56 to 58.5 cm) |
The head sizes are typical ranges; measure the wearer if you can. Instructions give the smaller size first with the larger size in parentheses: 104 (112). Where only one number appears, it applies to both sizes.
Abbreviations

The pattern
Brim
- With the US 4 (3.5 mm) circular needle, CO 104 (112) sts. Cast on loosely; a cotton edge will not stretch to make up for a tight cast-on.
- Pm for the BOR and join to work in the round, checking that the stitches are not twisted around the needle.
- Rib rnd: (K1, p1) to the end of the rnd. The repeat uses 2 sts and is worked 52 (56) times.
- Repeat the rib rnd until the brim measures 1.25 in (3 cm).
Body
- Change to the US 6 (4 mm) circular needle by knitting the next rnd onto it.
- Knit every rnd until the hat measures 5.5 (5.75) in, or 14 (14.5) cm, from the cast-on edge.
Crown
The crown is shaped in 8 sections. Change to the DPNs when the stitches no longer reach around the circular needle. For the reasoning behind the layout, see the guide to crown decreases.
Larger size only, set-up: (K12, k2tog) 8 times — 104 sts. Knit 1 rnd.
Both sizes now have 104 sts and continue as follows:

- Rnd 17: (K1, k2tog) 8 times — 16 sts.
- Rnd 18: k2tog 8 times — 8 sts.
Finishing
- Cut the yarn, leaving a tail of about 8 in (20 cm). Thread it onto the tapestry needle, run it through the 8 remaining sts twice and pull snug to close the top.
- Weave in both ends on the inside. Cotton is smooth and ends can work loose, so weave each one in for at least 2 in (5 cm) and change direction once along the way.
- Wash the hat as the yarn label directs, reshape it and lay it flat to dry. If the label uses symbols, the Craft Yarn Council care symbols chart explains them.
Watch out
Do not hang a wet cotton hat to dry. The weight of the water pulls the fabric longer, and cotton will not spring back. Dry it flat.

Ways to adjust it
Add a little slouch
Knit the body 2 in (5 cm) longer before starting the crown: to 7.5 (7.75) in, or 19 (19.5) cm, from the cast-on edge. The crown is worked the same way. Allow roughly 40 yd (37 m) of extra yarn as an estimate.
Change the brim
Both cast-on numbers are multiples of 4, so k2, p2 ribbing fits without any change to the count: work (K2, p2) 26 (28) times around. For a softer edge with no ribbing at all, begin on the US 6 (4 mm) needle and knit every round from the cast-on; the edge will roll up, so add about 1 in (2.5 cm) to the body length. Because a rolled edge has no grip, it suits the smaller size on a given head. The comparison of hat brim styles covers the trade-offs.
If the hat feels loose after a few wearings
Cotton relaxes as it is worn. Washing and drying it flat usually brings the fabric back to size. If you are between sizes, the smaller one is the safer choice in cotton.
Frequently asked questions
Is cotton yarn good for knitting hats?
Yes, for mild weather. Cotton makes a light, smooth hat, but it has little stretch, so the hat needs a firm gauge, a snug ribbed brim and a size chosen close to the head measurement.
Why is this cotton hat sized closer to the head than a wool hat?
Cotton fabric does not stretch and spring back the way wool does. A cotton hat with a lot of negative ease feels tight, so this pattern keeps the ease at the smaller end of the usual range.
Can I knit this beanie in wool instead?
Yes, as long as the yarn is DK weight (3) and the gauge is 22 stitches to 4 in (10 cm). A wool version will be warmer and more elastic, so it will fit a slightly wider range of head sizes.
How should a cotton hat be dried?
Flat. A wet cotton hat is heavy, and hanging it lets the weight of the water pull the fabric longer. Reshape it by hand and leave it on a towel to dry.
