Step 1: Measure your finger by wrapping a strip of paper or wide tread around it, leaving enough space to slide the ring over your knuckle.

Step 2: Mark the place where the paper strip meets and measure the length by using a ruler.

This is the circumference of your finger, which corresponds to European ring sizing. E.g. if it measures 5,4 cm you should choose a size 54. If you fall in between sizes, we recommend that you chose the larger size.

As a rule of thumb, you can always remember that you will probably need a slightly bigger size is if the ring is wide versus slim. If the ring is sleek and slim we recommend that you opt for a lightly smaller size eg. 0,5 size difference.

This method can be used to find the ring size of any of your fingers.

Please note that the ring size can vary depending on the ring design and fit on your finger.
