There are ​so many crochet baby hat patterns available that you could make a new one each day for years and never run out of patterns to follow. However, you don't really need a crochet pattern to be able to make a baby hat.

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.

That's what you will learn how to do when you work through the steps of this tutorial. Once you learn how to do it, you won't ever have to rely on a pattern again to make a baby hat!

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.

Crochet Hook:
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. If you find that you aren't getting the size that you want with the crochet hook then switch to a smaller or larger crochet hook accordingly.


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.


    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. There are 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.

    Common sizes:

    • Preemie: 6.5” wide
    • Newborn: 7” wide
    • 3 to 6 Months: 7.5” wide
    • Baby: 8” wide
    • Toddler: 9” wide

    Here's one example of the math for a newborn size hat:

    From the list above you can see the baby size is 7” wide. To learn how many stitches wide the piece needs use this equation: 7 (hat width) x 2.5 (stitches per inch) = 17.5 stitches. Once you have your math, you might want to round up a little bit, since a larger hat is always a better decision where babies are concerned. They grow so fast!

    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.

    For example, using a single crochet stitch, you might chain 19 to get the 18 stitches needed plus 1 extra for the turning chain.

    Foundation RowChain 1, 2, or 3 (depending on your stitch), work 1 stitch in every chain space across row, turn.

    Row 1Chain 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.


    You may choose to switch to a finishing color to accent your main color at this point. Alternative, simply 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 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.
