2. Place the ring on a ruler and simply measure the internal
diameter of the ring. Make sure that you measure

3. Once you have the inside diameter you can check
which size is right for you with the guide below.
Do you already know your UK, US or EU ring size? Check in the ring size chart below which size would fit best. The column most left refers to both Anna + Nina's sizing as well as the ring diameter in mm.
Example 2: In case your own ring has a diameter of 15,10 mm / 0.59 inch, your ring size would be a size 15.
