Ring size measurements can vary depending on the country. For example, the US and Canada use numerical sizes starting from 2, while the UK and Australia use letters (such as D, E, F). This difference can sometimes cause confusion when purchasing jewellery internationally. The chart above provides a simple way to compare sizes across these regions, ensuring a perfect fit no matter where you are.
