Methods to Measure Your Ring Size

1. Measure Your Finger with a String or Paper Strip

  • Encircle the base of your finger with a piece of paper or rope.

  • Mark where the ends meet.

  • Measure the length in millimeters.

  • Use our ring size guide conversion chart to match your measurement.

Pro Tip: When your finger is at its largest at the end of the day, measure it. Your fingers may shrink if you measure in chilly weather.

2. Use a Ring You Already Own

  • Take a well-fitting ring and measure its internal diameter in millimeters.

  • Match it with our ring size conversion chart.

3. Printable Ring Sizer or Plastic Sizing Tool

Irha is planning to offer a downloadable and printable ring sizer for our customers soon. It will provide a convenient and accurate way to determine your size right from home.

Additional Tips on Sizing and Fit

Check Your Knuckles

Your knuckle should be just a little bit bigger than your finger's base. Make sure the ring can slide over the knuckle without too much force but still sits snugly at the base.

Consider Finger Swelling

Hands swell throughout the day due to heat or activity. It’s always better to size for the largest your finger gets to avoid discomfort.
