Check your Ring Size

When buying rings online or ordering custom-made rings, it's vital to ensure you choose the right ring size. That's why we've produced these handy international ring size charts & tools below, cross referencing ring sizes in different international markets. 

Steps to Manually Determine your Ring Size:

  • Wrap a piece of string or a strip of paper around your finger.
  • Mark the point where the two ends meet.
  • Measure the string or paper against a ruler to get the circumference of your finger.
  • Divide that by 3.14 to get the diameter of your finger.
  • Look up your ring size using the form above.
  • Recheck using the downloable Ring Sizer file available below.
