Skill Level: Easy
A crochet baby hat can be as easy as a rectangle that is sewn (or crocheted) together along the sides. This square top baby hat style is within the reach of even the newest crocheter.
In this pattern recipe we’ll walk through the necessary steps and learn how to crochet a baby hat in its most basic form. You’ll begin by choosing materials (yarn and crochet hook). We’ll then determine your gauge and how many stitches you need to make the size baby hat you want.
Step 1: Choose Your Materials
Your choice of yarn. Use the list below as a guide for how much yarn you’ll need for each size hat.
Preemie Hat: 35 to 40 grams
Newborn Hat: 40 to 45 grams
3 to 6 Months Hat: 45 to 50 grams
Baby Hat: 50 to 60 grams
Toddler Hat: 60 to 70 grams
If you’ve never crocheted for babies before then you may wish to read the article Yarn for Baby Hats for advice on choosing the best materials.
Select a crochet hook that works with your yarn. If you’re unsure then check your yarn’s label. Most manufacturers will print a recommended hook size near the care instructions.

For my baby hat I used Lion Brand Yarn Baby’s First, which is a bulky weight blend of 55% acrylic and 45% cotton. I chose a size K/6.5mm crochet hook as suggested by the manufacturer. My main color is “Pixie Dust” and the coordinating color is “Sea Sprite.” Choosing a coordinating color is optional.
Step 2: Find Your Gauge
With your chosen yarn and crochet hook, make a chain 10 to 20 stitches long and work a few rows in your desired stitch.
Measure your practice piece and take note of how many stitches you get per inch. You’ll use this information in the next step.
For my hat I got 2.5 single crochet stitches per inch.
Step 3: Do the Math
In Step 2 you determined how many stitches per inch you get with your chosen materials. Now you’ll multiply that number (stitches per inch) by how many inches wide you want to make your hat. I’ve listed some common sizes below to get you going, however you can easily insert your own numbers for a custom fit. If you decide to do this then measure the head circumference of the hat recipient and divide it in half. Multiply that number by your stitches per inch.
For my sample I decided to make a newborn size hat. From the list below you’ll see the baby size is 7” wide. To learn how many stitches wide my piece needed to be I worked this equation:
7 (hat width) x 2.5 (stitches per inch) = 17.5 stitches. I chose to round up and make my number 18 since a larger hat is always a better decision where babies are concerned.
Preemie: 6.5” wide
Newborn: 7” wide
3 to 6 Months: 7.5” wide
Baby: 8” wide
Toddler: 9” wide
Step 4: How to Crochet a Baby Hat
Chain the correct amount for the number of stitches you need. If you’re working single crochets make a chain 1 stitch longer than your calculation. For half double crochets add 2 sts. For double crochets add 3 stitches.
Since I used single crochet I chained 19 to get the 18 stitches I needed plus 1 extra for the turning chain.
Foundation Row: Chain 1, 2, or 3 (depending on your stitch), work 1 stitch in every chain space across row, turn.
Row 1: Chain 1, 2, or 3 (depending on your stitch), work 1 stitch in every stitch across row.
Repeat Row 1 to work even in your pattern stitch until your piece is desired length for hat. Use the numbers in the list below as a guide.
Preemie: 4.5” long
Newborn: 4.75 to 5” long
3 to 6 Months: 5 to 5.5” long
Baby: 5.5” long
Toddler: 6 to 6.5” long
Cut yarn and fasten off.
Make a second piece exactly the same as the one you’ve just completed.
I used my coordinating color to finish the baby hat. You may choose to do this or continue with your main color.
To finish the hat you can either sew or crochet together 3 edges of your piece. Hold the pieces you’ve crocheted on top of each other with both foundation chain edges at the top and ending rows at the bottom.
Using whipstitch (sewn method, as shown in photos) or single crochet, work up one side of the hat securing the edges together, then across the foundation chains, and down the other side. Leave one edge open.
Embellish the hat however you’d like. Embroider on it, add tassels or pom poms to the top corners, sew on patches, bows, and crocheted flowers. The final choice is yours. Have fun adding your personal flair.
