The easiest way to find the correct size is to measure the diameter of a ring you already own.

• Choose a ring you already own that fits well on the desired finger.
  
• Place the ring on a ruler or tape measure.
  
• Measure the inside diameter of the ring, from one side to the other, in millimeters.
  
• Compare the measurement obtained with our size guide.
  

Alternatively

You can also download the RingSizer app and place the ring directly on the screen to measure it quickly and easily.
