Ring Sizer

Find your perfect NORIDU ring size with our online ring sizer

To measure your ring size, take a well-fitting ring. Measure the diameter of the inside of your ring and use the converter chart below to find the correct EU ring size.

Alternatively, to measure your ring size use a flexible measuring tape and measure the circumference of your finger. If you don't have a flexible measuring tape, you can utilise a piece of paper or string instead (no thicker than 0.5 mm) and then measure the length of it with a ruler. This will the circumference of your finger. Use the converter chart below to find the correct EU ring size.
