Ring size guide. Ring conversion chart

If you are not sure of your Claddagh ring size we strongly recommend you visit your local jeweler. However, if you cannot get to a jeweler you can either use the ring size guide outlined below or we can send you a Free Ring Sizer.

Please note ring sizes other than the ones specified are custom made and we ask you to contact us for a quote. Custom-made rings are not covered by our standard 60-day return policy unless the goods are faulty.

How to find your ring size

  • Find a strip of paper.
  • Wrap it around the base of the appropriate finger. Make sure the paper fits snugly. You should be able to slip it over your knuckle.
  • Using a pen – mark the point on the paper where it overlaps forming a complete circle.
  • Measure the length from the starting end of the paper to the pen mark using a ruler with a millimeter measurement.
  • Check this measurement with the chart below to determine your ring size.
  • Below is a ring size conversion chart for our international customers:
