The ring sizes shown on Heybijou are US sizes based. If you don’t know your US ring sizes, you can easily use this ring size converter by input the size based on your system and get the corresponding US ring size or the sizes based on the other systems. 

How it works:

  • Base Size Input: Inputs a base ring size.
  • Base System: Selects your base system (US, UK, EU, Japan, or Australia).
  • Convert Button: When clicked, the button calls the convertSize function, which converts the base size to the other systems.
  • Size Conversion: The results are displayed dynamically below the converter.
