Find your ring size
There are several ways to find your ring size. Try one of the ones below.
For stacking rings, we recommend a slightly looser size.

A) Measure one of your own rings
Take a ring that fits you well and measure the inner distance (diameter).
Use the chart below to translate your measurement to the correct size.

B) Measure the circumference of your finger
1) Use a strip of paper and wrap it around your finger. Make sure it fits over the knuckle.
2) Use a pen to mark where the paper overlaps and unfold it flat again.
3) Measure the length of the paper from the start to the mark using a ruler with mm measurements.
Use the chart below to find your correct size.

LULU Copenhagen’s size guide is an overall guide, and the measurements can therefore vary according to person and the chosen style.
Not all styles have the same shape, so even if you find your ring size, it can be affected by the design and the thickness of the material in the ring. Which means you will have to go either up or down in size.
Please use this guide as an overall reference for your choice of size.
