I’m here to tell you that it’s actually pretty easy to crochet a perfectly sized hat with just knowing a few key tips while using our sizing table below.
Taking Crochet Hat Measurements
The first step in correctly creating a crochet hat or beanie is determining which size you need to make. There are two ways to do this:
Measure your recipient’s head. To accomplish this, take the tape measure and wrap it around the person’s head at the forehead level. Take this measurement and find it in the “Head Circumference” column of the table below. This will tell you the “Size” of the hat you need to make.
Estimate it based on age. If you don’t have your recipient next to you, or this is for a gift, then you’ll have to make an estimate. The table below lists average sizes for specific age groups. If you are making a hat for someone slightly smaller or larger than their peers, then you may want to go up or down to the next size.
Average Crochet Hat/Beanie Size Chart
This crochet hat sizing guide lists the average crochet hat sizes based on eleven different age groups. It is important to note that these measurements are the commonly used average sizes.
If you are making a hat for someone who has a size head that little smaller or larger than their peers of the same age, then you will likely need to adjust the crochet hat size up or down appropriately.
|Adult Large||Adult Man||23||22||8||9.5|

|12-24 Months||1-2 years||17-18||16-17||5.5||6.5|
|Adult Large||Adult Man||58.5||56||20.5||24|
|Adult Medium||Adult Woman||56||53.5||19||23|
|12-24 Months||1-2 years||43-46||40.5-43||14||16.5|
Understanding Crochet Hat & Beanie Dimensions
The table above has four different dimensions, all needed to make your crocheted hat the perfect size. Each dimension has its specific use, and deviating from it will result in a hat that is either too big, too small or the wrong shape.
Here, I break down what each of these dimensions are for and how to get or use them in your crochet hat project.
The head circumference is the measurement around the person’s head at the forehead. This is usually the measurement needed to determine which size of hat you’ll have to crochet.
The hat circumference measurement is often around 1-2 inches (2.5-5 cm) smaller than the head circumference. This is the case, so the hat fits snugly over the head.
The crown diameter is how wide the very top of the hat should be. To use this dimension, measure your starting circle across and use the chart to determine when to stop increasing your circle’s diameter.
The hat height is typically measured from the top of the crown to the bottom of the person’s ear. If you expect to wear your hat to the top of the ear (instead of the bottom), then you will need to subtract an inch (2.5 cm) off the estimated height.
If you’d like to be able to have a folded brim, then add an extra inch (2.5 cm) to the height of the hat.
