We have a few helpful tips to make sure you get the right hat size. You’ll need a measuring tape (preferably in cm for accuracy) to measure your head and match it with our size chart below.

However, before you get to that you’ll need to decide how you want to wear your hat. There are two main options: halo and traditional. It is important to measure your hat to your preferred option to guarantee a desired fit.


If you wish to wear your hat ‘halo’ style you simply wrap the measuring tape around your head starting at the furthest part of the back of your head and ending at the top of your forehead or beginning of your hairline.


If you prefer to wear your hat in a traditional way, wrap your measuring tape around the widest part of your head right above your ears and your eyebrows or in the center of your forehead. This will depend on where you want the hat to sit.

Make sure that regardless of the style the measuring tape is not too loose or too tight. If your measurements don’t match exactly, we recommend going to the next size up.

If you have a hat that already fits perfectly, you can check its size tag and match it with our chart to determine the size of your Sol Authentica hat.

Once you have established your measurement, please use the sizing chart below to determine the size of your Sol Authentica hat. Our sizes are divided into simple small, medium, or large.

The columns list sizes in centimeters from 55 to 60, corresponding sizes in inches from 21 5/8 to 23 5/8, U.S. hat sizes from 6 7/8 to 7 1/2, and Sol Authentica's own sizes ranging from Small to Large. The chart is designed to help customers find their perfect hat size for a comfortable and stylish fit.

Final Notes

Different people like to wear their hats in different ways. Although these are our general recommendations to establishing a hat size, there is no one correct way.

Whilst a tighter hat may be better for a day at the beach or horseback riding, a looser hat might be more comfortable for a relaxed, extended period of time. It is ultimately up to you to determine how to wear it.
