Sizing For Crochet Hats
Hat Sizes For Crochet – Measuring By Age
Sizes by age can drastically differ from person to person, so size should not be determined by age alone.
For example, not all newborns have a 12″ head.
And, not all adults have a 22″ head.
Finally, not all hat styles are the same size (more on that next).
For the best fitting hat, always measure the head first and then create a hat based on that specific size.
Hat Sizes For Crochet – By Style
Our crochet hat size chart can not (and does not) account for all styles of crochet hat.
That is because some hat styles should be fitted; that means the exact measurement of the hat fit the exact measurement of the head.
And, some hat styles are slouchy; that means the exact measurement of the hat can fit the circumference of the head, but is longer for a slouchy look.
For slouchy styles, the exact measurement of the hat can also be wider than the circumference of the head for an oversized look.
That is why knowing the size of the head, and the intended style, will help you to crochet the right look and fit.
Crochet Gauge and Size
Crochet hats are projects where your gauge and size should match the gauge and size outlined in a pattern.
To do that, be sure to use the same yarn and hook size a pattern calls for so that your stitch and row gauge will be an exact match to the pattern gauge.

How To Crochet In The Round
Crochet hats can be made in many different ways: rows, tubes, rounds, and combinations of all!
Because crochet hats can be made in rounds, from the top down, those are most often the trickiest to make and measure as you go.
But now that you have our handy tips about measuring circumference and diameter, you can try to make your very own crochet hat using any basic crochet stitch you want.

Hat Sizes for Crochet
When you need to crochet the best fitting hat sizes, there are three main measurements to understand:
- Circumference
- Diameter
- Height
You can use circumference or diameter to measure the actual stitches you’re creating to crochet perfectly sizes hats!
This is where the math gets exciting…
The number 3.14 (Pi) is going to feel like magic, but really it’s just a helpful math tool!
In the math world, Pi is the ratio of a circle’s circumference to the diameter.
In the crochet world, Pi is going to easily help to calculate the circumference and diameter of your own personal crochet stitch work.
Crochet Hat Circumference
This is the measurement around a circle.
For a fitted hat, the circumference of a hat should be the same as the circumference of a head.
Let’s give it a try, starting with the circumference (see the previous image for reference).
If you know what size hat you want to make, divide that number by 3.14.
Example: 22” circumference / 3.14 = 7.006369″
And so, to crochet a hat with a 22” circumference, the diameter of your beginning circle should reach about 7”.
Crochet Hat Diameter
This is the measurement across a circle.
When crocheting in center-out increasing rounds, the diameter is the cross section of a circumference.
Let’s give it a try, starting with the diameter (see the previous image for reference).
To check what size hat you are making, multiply the diameter by 3.14.
Example: 7” diameter x 3.14 = 21.98”
And so, if your diameter measures 7”, the circumference of the hat you are crocheting will be about 22”.
Crochet Hat Height
This is the measurement of the total length.
When crocheting a hat, the height can refer to the size of the head or the total length of a hat.
To get this measurement, use a fabric tape measure from the center of one ear, around the top (crown) of the head, making sure to get the center most point.
This measurement should give you an accurate measurement of the total height of a fitted hat for that particular head.

I too have been crocheting since I was 5. My mother taught me while doing her own projects. Hardly a day goes by that I don’t pick up and work on a project.
I enjoy knowing people with like interests. Much more alike than different, we all are connected in many ways. Crochet ROCKS!!
