Below is our ring size conversion chart. It shows sizes in diameter and circumference in both mm and inches. There is no difference between men's and women's ring sizes, so this chart applies to everybody.
We've included conversions for the numerical (USA), alphabetical (or Wheatsheaf) and European ring sizes. The alphabetical or Wheatsheaf system is used for Australian ring sizes, but most jewellers in Australia will also accept the USA numerical system.
ISO sizes are used in some European countries, but these size numbers simply correspond with the internal circumference in millimetres. Some European countries use a slightly different system where 40mm is deducted from the ISO size (so a ring with a 44mm circumference will be a size 4 in this system).
Note that measurements for different international ring sizing systems don't precisely align, so this chart shows a close equivalence across the different systems based on commonly used USA ring size measurements. These differences are tiny enough that they shouldn't affect your chosen ring size, no matter which sizing system you're using.
