Ring Sizing

Accurate ring sizing is essential for a comfortable, secure and flattering fit for your finger jewel. Learn how to measure your finger and choose the perfect ring size with our guide.

There are several different ring sizing systems used around the world. Understanding these systems will help you accurately determine your ring size and ensure a perfect fit.

  • US Size: This is the most common system in the United States and Canada. It uses a numerical system, starting from size 0.

  • UK / AUS Size: The UK uses a letter-based system, starting from A.

  • EU Size: The European Union uses a numerical system, starting from 48.

If you already have your ring size in one of these, please see the chart to help you convert between different systems. Please note that these conversions may vary slightly depending on the specific country or region.


If  you do not yet know your ring size, there are a few ways to find this. 

  1. Measure your finger with a paper strip. This video explains this method clearly. 

  2. Measure the internal diameter of a ring that fits you well. If doing this, consider how thick the ring band you want is in comparison to the band you are measuring.

  3. Purchase an adjustable ring sizer online. 

  4. Visit DK’s atelier in Paris, or a local jeweller near you and ask to be measured.
