The Basics of Hat Sizing

Hats come in many different styles, shapes, and sizes. Believe it or not, so do heads. That is why it is such a challenge to find a hat that fits your head perfectly. Learn more about how to measure your head and choose the right size of hat—no matter what style of hat you are buying!

Measuring your Head

No matter what type of hat you buy, you will want to measure your head before choosing the size. However, it is important that you measure your head correctly to get the right fit. Use a soft tape measure or if you do not have this, use a string and then measure it with a ruler. Hold the tape measure or string around an eighth of an inch above the tops of your ears—across your forehead. Measure snugly, but do not squeeze.

Adult Caps

Caps can come in "fitted” sizes as well as stretchy sizes that are easier to fit. No matter how the fit works, the first thing you will do is measure your head. Then, based on the results of the measurement, you’ll choose the right hat. Here is a basic guide that may help you choose the right size:

The hat arrived yesterday and my husband is so happy to have it back. You did an excellent job with the restoration. Thank you so much.


I just received my old hat which you made almost like new. The lining is perfect and you didn’t spoil the hats character. I’ve had this hat for 30 years and you have made it so beautiful; I’ll have it for a good time more! Thank you very much and may the Lord bless you all! Keep looking up.
