Determine the right ring size

You don't know your ring size? In order to give a ring as a gift or to buy a pretty ring for yourself, you naturally need the right ring size. Here we show you different methods to measure your ring size quickly and easily, so that you don't miss out on the joy of your new piece of jewellery because of the wrong size.

Determine ring size with a ring

You can easily measure and compare the right ring size with another ring. Find a ring that fits well. Now there are several options:

1. measure diameter

You measure the diameter of the ring with a tape measure or ruler and look in the conversion table to see which ring size fits.

2. ring size chart

You print out our ring size chart and place the ring on the template. The circle with which the ring overlaps is the correct size.

Determine ring size without ring

If you don't have a matching ring at hand, there is also a way to determine the ring size.

1. paper or thread

Take a piece of paper or thread and wrap it around the desired finger. Attention: The paper or thread must also fit over the joint of the finger. Now cut the paper or thread where it once encircled the finger. Then measure the length of the paper or thread to determine the circumference and compare your result with our ring size chart .
