As already said in our article about how to measure your correct ring size, the best way to figure it out is visiting local jeweller or any jewelry store. Professional will help you better than any home method! Here at Eden Garden Jewelry we use US size standards and you can use this trustworthy conversion chart in case if you got different standards measurements. 

If you live in Germany, there's common to use inside circumference measurements. For example, German size 55 means that your ring's circumference is 55 mm and in US size chart this will be 7 1/4. 

Common European standards use inside diameter. It means if jeweller said you have size 16.5 mm you shall choose size 6 US when purchasing one of our rings.
