Ring Size Tester

Not sure what your ring size is?
Use our free ring sizer tool!

  • Measure your finger at midday in room temperature.
  • Use our Ring Sizer tool like a belt and tighten it around the base of your finger until it is snug (but not tight).
  • When you go to take it off, it should move over your knuckle with slight resistance.

The goal is for your ring to be a comfortable middle ground between falling off and being too tight.
