Common questions
How do I make sure the ring sizer prints at the right size?
Print on A4 with scaling set to 100% or Actual size, not Fit to page. The ruler should measure 50 mm and a bank card should fit the box exactly.Which ring sizes does Australia use?
Australia uses the UK letter sizes in half steps, continuing Z+1, Z+2 and up above Z. This sheet is marked in them; our ring size converter gives US and EU equivalents.What if I’m between sizes?
Choose the larger size, and make sure the ring will still slide over your knuckle. Our jewellers can confirm your size in store.
