Below is our full Ring Size Chart. It shows ring sizes in both mm and inches, plus internal diameter and external diameter. It also shows conversions between the numerical (USA, Asia) and alphabetical (Australia, UK) ring size measuring systems. The same chart covers ring sizes for both women and men as they both use the same systems of measurement.
