Neon Crochet Hat

How to Crochet a Rainbow Hat

The brightly colored crochet hat is worked in one panel and sewn together at the end, which makes it easy to crochet for almost any level of crocheter. Plus, the neon rainbow yarn color is all in one skein, which means less ends to weave in when you are done crocheting your hat!

It can be worked up in less than a day because this hat uses basic crochet stitches. This is always a good thing when making crochet projects.

The initial chain of this beanie will be the height of the hat pattern, and the rows worked will be the width. You’ll be able to use the hat size chart below, so you know exactly the perfect size crochet hat to make.

To learn how to make this cute crocheted hat, scroll down and read about the yarn and stitches used.

The Yarn

To create this hat, I used Red Heart Super Saver Stripes in the color Retro, which is such a standout and bright neon color! If you know someone who is a fan of neon, then this is the yarn you’ll want to use for them.

Red Heart Stripes is a 100% acrylic four weight yarn that is so fun to work up because of all the striped color changes it creates.

This yarn is available in nine different striped colors and 40+ solid colors, so you can use whatever color you feel suits you or the person you are crocheting this hat for the best.

The colorway Retro was a bit harder to find than some other striped colors available, so I had to do some searching to find the two skeins I got.

If you are lucky, you may find it online on Amazon, or direct from the manufacturer at I ended up going into my local Joann Fabrics Craft store and found the last two skeins, which one of was destined to become this funky crochet hat.

Take a look at a few of the other striped yarn colors available below that you can crochet a hat in: Candy Stripe, Parrot and Bright Stripes!

Crochet Stitches for a Hat

This easy crochet hat uses easy crochet stitches, so any level of crocheter could try to make this if they are feeling adventurous.

  • single crochet
  • herringbone half double crochet

The best part (in my opinion) about this hat is that it only uses two simple crochet stitches! If you can single crochet (sc) and herringbone half double crochet (hddc), then you are good to go with crocheting this colorful design.

Since this hat is made in one panel you will work the single crochet brim of the hat first followed by the hddc which is the main part of the hat.

Take a look below at the picture to see where the single crochet section and herringbone half double crochet stitches begin and end within the hat. You will also be able to see how the brim of the hat is made.

The brim of the hat is single crochets that are worked in the back loop of the previous row’s single crochet stitches, which creates the cuffed brim look.

Crochet Hat Size Chart

Changing the size of a hat is as simple as changing the width of the hat as well as the height. You can use the crochet hat size chart below that shows the average circumference and height of crochet hats in inches.

Circumference (in)9-1214-1616-1818-2020-2221-2322-24
Height (in)4-4.55-67-7.57.5-88-8.58.5-99-9.5

How to Measure Hat Size for Crochet

Measuring a crochet hat is easy. You’ll need a soft tape measure and a person to measure, so you can get the circumference of their head. For example, if you want to make a men’s crochet hat, you would crochet your hat to a width of 22 to 24 inches with a 9 or 9.5 inch height.

Be sure to measure that person’s head, so you will get an exact measurement. Use the same method with any size of crochet hat you want to make from the chart.

The best bet is to always measure the circumference of the person’s head you want to make the hat or beanie for because their size may differ from the standard sizes on the chart. If it is not possible to measure, then you can go by the standard chart above when crocheting a hat.

Below, you’ll be able to see the sizes I designed this hat for, so you’ll know how many chains and rows to crochet to get the size you need.

Crochet Hat Sizing Tip: I suggest crocheting your hat 1–2 inches less than the actual circumference of the person you are making for to allow for stretch and give.

How to Make a Crochet Hat Slouchy

If you’d like to crochet a slouchy hat, all you will have to do is add some height to the initial chain. For example, in this pattern to make a women’s hat size you are supposed to chain 25. To make it slouchy, you can add any number of chains to that first chain length to give this design a slouch hat look.

To add slouch to crochet hats, I like to add between one and two inches in length, which for this pattern is about 3 chains per inch. You can work up the pattern and add chains to see what number you’d like to make the style of hat you are going for.

Joining the Hat

To join the panel together to form a hat, you will lay it down flat. Join the two short ends together. Attach the yarn needle to the yarn tail. Weave up the side of the hat to join the two short ends of the panel together to form a tube.

You can use the mattress stitch to join also, but it is up to you to use the method you feel more comfortable with when you close up this hat.

I have a great post about seaming crochet pieces together if you’d like to take a look, so you can find your favorite way to seam up a crochet hat.

Once you reach the top, you will use the yarn needle and weave along the top of the hat in and out, pulling in every few stitches to tighten up the top of the hat until you reach the beginning.

I like this video on how to close the top of a hat. This video is a great tool to use and has clear finishing hat instructions.

Next, weave in the yarn end back and forth through the top of the hat to secure. Finishing with the yarn tail on the inside of the hat.

Finishing: Weave in all remaining ends of the hat with the yarn needle! You are done with your new crochet hat!

  1. G’day Krista,
    Thanks for the gorgeous neon rainbow beanie pattern. Weird question however the pattern for eg toddler size row 1 is only 14ch which is around 5” across !!!!!!!
    Am I completely miss reading the pattern ??
    Kind regards Leanne

    1. Hi Leanne,

      The toddler hat size starts with a chain 21 which is the height of the hat and the rows worked after are the width. I hope this helps. 🙂


  2. Hi so I loved this pattern and completed it but the finished product does not reach 21 inches laid flat despite me following it? Any advice of what to do next

    1. Hi Taylor,
      My best guess is that your gauge was a little off from the recommended 8 sts x 6 rows = 3″ x 3. You can add more rows to make it to the width you’d prefer. If you have any questions, please let me know.


      1. What size hook do you use to get the gauge? I’m using the exact same yarn and no matter how I change the hook size, I can’t get the gauge swatch up to the right size. It keeps coming out too small, and of course the larger hook sizes make larger holes in the product, but it doesn’t necessarily get any bigger. Please help!

      2. Hi Chloe,
        I used a 5.5 mm crochet hook for this hat. 🙂 Are you using the same yarn as well? Sometimes that can change the sizes as well, since all four weight yarns are not made the exact same thickness.


  3. I made the hat different yarn( stuff I had) I think I did the hhdc wrong but…it lookycool still. First hat ever! Thanks for the great simple pattern!

  4. The hat is gorgeous! How many skeins did you use? I think I need to make a tween size. Thank you!

  5. I love the colors in the Retro Stripes. Being thinking of a project and now I have found one.
