Useful Tips

  • Throughout the day: Fingers naturally change size. Try your sizer in the morning and evening.
  • The right feel: A good fit slides over your knuckle with gentle resistance, without spinning loosely.
  • Take your time: If you're not in a rush, wear your sizer for several days or up to a week. Try sleeping in it if that's how you'll wear your ring.
