On which hand goes the wedding ring?

In Germany, wedding rings are traditionally worn on the ring finger of the right hand. In many other countries, such as the United States, the United Kingdom, or France, however, it is customary to wear them on the left hand. There is therefore no single, universal rule.
Even in Germany, couples are free to decide on which hand they would like to wear their wedding ring. Practical reasons, personal preferences,
or family traditions can all play a role in this decision. The widespread custom of wearing a ring on the fourth finger dates back thousands of years. The ancient Egyptians and, later, the Romans believed that a special connection ran from the fourth finger to the heart—the so-called “vena amoris” or “vein of love.” Although modern anatomy cannot confirm this actual connection, the poetic symbolism has endured and has become a tradition in most countries.
