*PLEASE NOTE - If you are between sizes, we generally recommend sizing down. See below for more details.

Our caps are sized in CMs to get the best fit.  Find your measurement in CMs, then pick a hat size based on that measurement. 

*NOTE - Target Hat Size may very cap to cap, use Hat Size CMs for best fit guidance.

Finding your measurement: 

If you have a soft measuring tape, that's the best route to take. If you do not, use a string, phone charging cable, or anything else you can wrap around your head. 

How do I measure my/someone else’s head?

Step 1: Wrap the soft tape, string, or cord around your head above your ears and eyebrows, where you your cap usually sits.

Step 2: Double check to make sure the tape comes down far enough at the back of your head, hitting in the right spot.

Step 3: Take note of your measurement in CMs, if using a string or cord, mark where it meets so you can measure it using a traditional tape measure.

Step 4: Refer to the sizing chart above to see where you land. 


Are you in between sizes??

For our comfort fit flex back caps, we always recommend sizing down.  For our fitted caps, size up for a loose fit and size down if you prefer snug.  Caps will usually stretch slightly, but rarely do they shrink.

Will my size be the same as the other caps I purchase from other brands?

Unfortunately there is no universal sizing, so a Medium for one brand might be a small for another.  We highly recommend you measure your head to ensure you have an accurate size before ordering from Peaky Hat.






*PLEASE NOTE - most hat sizes tend to run half a size big.

If you are between sizes we recommend choosing the smaller size.
