How to crochet a hat

What size should a crochet hat be?

A crochet hat should measure 1–2 inches less than the wearer's head circumference for a snug fit. An adult woman's head measures about 21.5–22.5 inches, so a hat circumference of about 20–21 inches fits well.

How do you crochet the crown of a hat?

Crochet the crown of a hat by increasing evenly in each round until the flat circle reaches the target diameter.

1. Make a magic ring, chain 2 (does not count as a stitch), and work 12 double crochet into the ring; join — 12 sts.
2. Round 2: chain 2, work 2 dc in each stitch around; join — 24 sts.
3. Round 3: chain 2, *1 dc in next st, 2 dc in next st; repeat from * around; join — 36 sts.
4. Round 4: chain 2, *1 dc in each of next 2 sts, 2 dc in next st; repeat from * around; join — 48 sts.
5. Continue adding 12 stitches per round until the circle measures the target diameter, for example 6.4 inches for a 20 inch hat.

How do you crochet the body of a hat?

Crochet the body of a hat by working even rounds with no increases until the hat reaches the target height.

1. Chain 2 and work 1 dc in each stitch around; join.
2. Repeat the even round, measuring from the center of the crown after every round.
3. Stop when the hat measures 1.5 inches (4 cm) less than the target height to leave room for the brim.

How do you crochet a hat brim?

Crochet a hat brim with 3–4 rounds of single crochet, or with alternating front post and back post double crochet for a stretchy ribbed look.

Post-stitch ribbing pulls in slightly, which helps the hat grip the head.

Why is my crochet hat too big?

A crochet hat is too big when the crown is increased beyond the target diameter or the crocheter's gauge is looser than the pattern's. Measure the flat crown before starting the even rounds, and use a smaller hook if the gauge swatch is too large.
