Not sure what your ring size is? No problem. Use this ring sizer to determine your ring size on any finger. Make sure to look for a secure, but not too tight fit (make sure you’ll be able to get the size you choose over your knuckle). The right size isn't easy to slide off, but doesn't hurt to take off, either. Add this to your cart to have one included with your next order, or reach out if you’d like us to send you one in the mail instead.
