Method 1: Measure a Ring - Inter Diameter (mm)

  1. Find a ring that fits comfortably on the finger you intend to wear your new ring on.
  2. Measure the internal diameter of the ring, using a ruler or measuring tape. To do so, ensure you are using a ruler with millimetre (mm) measurements, then place your ring on top of the ruler and measure the inside of the circle – in other words, the part that is in contact with your finger.

Method 2: Measure a Ring - Inter circumference 

  1. Cut a thin strip of paper 10-12cm long. 
  2. Wrap the strip of paper tightly around your desired finger. 
  3. Using a pen or pencil, mark the point where the paper overlaps itself. 
  4. Lay the strip of paper on a flat surface and use a ruler to measure the distance from the end of the strip to the marking you made in millimetres. This will give you the circumference of your finger. 
  5. Using the below char convert your measurement into standard US sizing.
  6. If you are in between sizes, it's always best to round up rather than down.

 

 

🔹 Note: Your ring size may vary slightly throughout the day due to factors such as weather, humidity, or activity levels. We recommend checking your size at different times to ensure the most comfortable fit.
