TIP #1 MEASURE THEIR HEAD

The most accurate approach is to discreetly measure their head without arousing suspicion. This is the best and most precise method. Take their measurements and size them up in our size guide.

Tip #2 - Measure their cap

Measure the inside of a current ball cap they own. Note that results from this method may not be highly accurate, and this maneuver can be tricky. Take this inner cap measurement and size them up in our size guide.

TIP #3 - SMALL HEAD?

If they have mentioned having a small head, we recommend the XS/S size. The XS/S is slightly smaller than a traditional one-size-fits-most (OSFM) ball cap. If they've found OSFM caps too large, the XS/S will likely be a good fit.

TIP #4 - Big head?

If they have mentioned having a large head, we recommend the M/L size. The M/L is slightly larger than a traditional OSFM ball cap. If they've found OSFM caps too small, the M/L will likely be a good fit.

Tip #5 - Go with the majority.

If you're uncertain and want to make an educated guess, go with the S/M size. About 50% of people have this head size, giving you a 50/50 shot at getting it right!
