Ring Size Guide

Don't know your ring size? Download our printable ring sizer that can help you determine your ring size. Important! Prior to printing, ensure that page scaling is set to "100" on your print dialog box.

Tips: If you want to wear stackable rings (multiple rings on one finger) or wide band rings, please consider that the ring should be half or one size bigger than your regular size since multiple rings or wide band rings usually fit tighter than a thin band.
