Measuring for Your Cap/Hat Size

Because of the extra handling required, and the very high shipping fees for caps, we have had to begin charging a $5 fee to exchange any Blue Service Cap. Please take the time to measure before placing an order. And, if you have any questions, please contact us.

Take a look at our How To Measure Video on Headgear.

(Looking for general
body-measurement instructions
Ideally, try on a cap to best determine your size.  In the absence of a try-on, follow these steps:

Step 1:

Use a tape measure to measure around your head:
- across your brow (approx 1" above eye brows)
- slightly above your ears
- keeping the tape parallel to the floor
- this measurement is a "two-person" event and is nearly impossible to accurately do by yourself

For best results, use a plastic/cloth tape measure. Alternately, you may use a piece of string or cord and then measure the length of the cord.



Step 2:

For female sizes, your head measurement in inches will be your hat size. For male and generic sizes, divide the measurement in inches by 3.14 to obtain your cap size, rounding UP to the nearest 1/8".

Step 3:

Consider the shape of your head.  Service caps are preshaped to an average oval shape.  If you have a more narrow or round head than "average", consider adjusting up to the next higher size.


Upon receipt, your service cap should fit snug, but not too tight. Notice that the cap is parallel to the ground and is approximately one inch above the eye brows and ears.

How can my Blue Service Cap and beret sizes be different?

The service caps have a constant and relatively more-rigid shape than a beret, in addition, the beret will stretch a little over time.
