The wedding ring is traditionally worn on the ring finger of the left hand in many countries including the UK, USA, Italy, Spain, France, and Switzerland. This tradition is often linked to the belief in the "vena amoris," a vein thought to run directly from the left ring finger to the heart, symbolizing love. However, in countries like Germany, Austria, Poland, Norway, and some others, the wedding ring is commonly worn on the right hand. This tradition can be rooted in cultural and religious practices as well as practical reasons, such as handedness. Ultimately, whether the wedding ring is worn on the left or right hand depends largely on cultural, regional, and personal preferences, with both choices symbolizing commitment and love.
