Not sure of your ring size? We’ve now got an easy solution! These black ring sizers are now available as the perfect little add-on to your order! Durable and reusable, you can use your ring sizer for years to come.

If you haven’t noticed – all of our rings are measured in US sizing. There’s a simple reason for this! As a small business, we have a limited budget. This means when we’re making a new ring, we don’t have the ability to create over 26 different sized rings. We use US sizing so we can then create 6-8 rings for each release.

If you would like to use your ring sizer for UK sizes, simply use our conversion chart on this page!

  • After sliding the ring sizer on, make sure it slides off fairly easily over the knuckle.
  • Don’t measure cold fingers. This is when fingers are their smallest.
  • For the most accurate reading, measure the finger at the end of the day when the finger is the largest.
