When it comes to jewelry, one of the most important aspects is finding the perfect fit. Ring sizes can vary greatly from one country to another, which can be a challenge for international shoppers or those looking to gift a ring to someone overseas. This blog post will guide you through the basics of international ring size conversion.

Ring Sizing Systems

Different countries have their own ring sizing systems. The most common are the US, UK, and European systems. Each system has its own numerical scale, with the US and UK sizes starting from about 3.5 to 13, while European sizes typically range from 40 to 60.
