How to measure your ring size?

We think that this is the question we mostly get asked by our customers daily, which is totally understandable as there is nothing so difficult to measure a ring size. You may wonder why that is. Ring sizes need to be measured very precisely on the 00.00 mm. Every finger on both hands has a different ring size.

Ring size chart

We have managed to create a ring size chart that you can print at home to see which ring size comes the closest to your fit. You can use it for yourself, your partner, family, and friends.

There are a few important things you need to know before measuring your ring size with our chart:

1. Make sure you print the file at 100%. No ''Scale to fit, or ''Fit to page''. 

2. Follow the steps on the print.

3. Decide on which finger and hand you would like to wear the ring. Every finger on both hands has a different ring size.

4. Make sure the string can go over the knuckle of your finger where you want the ring to wear. (If it fits on the bottom of your ring but you can't get it over the knuckle, the ring would not fit)

5. Measure the string with a ruler where you can see 00.00 mm on.

6. You have now measured the circumference of your ring size which you can convert in the tab ''size mm'' on our Ring size chart.
