Not sure? Choose Regular.

If you’re not sure of your size, we suggest Regular, as this fits most men. And no need to worry - we’ll send you a free replacement (you pay only for shipping) if you need something a bit bigger or smaller. And size changes are "no-hassle". There's no need to return the original. We simply send you the replacement. 

Measuring circumference can be tricky. There's no exact science. As well, some men like the ring more snug, while some find a snug ring uncomfortable. For this reason, we encourage experimentation and will always change size for free with no hassle.
