Ring Size Chart & Guide

How to measure your ring size?

There are a few different methods you can use to find your perfect ring size. If you already own a ring in the correct size, you can physically measure it or use our printable ring size guide. If not, you can measure your finger! 

Method 1: Measure a Ring

  • Find a ring that fits comfortably on the finger you intend to wear your new ring on.
  • Measure the internal diameter of the ring using millimetres (mm) measurements by placing your ring on top of the ruler and measuring the inside of the circle.
  • Use our ring size chart to convert the diameter into your perfect ring size.

Method 2: Measure Your Finger

  • Cut a piece of string or paper to a length of around 10 centimetres (cm).
  • Wrap the paper or string around your finger at the point where the ring should sit. Pull so that it fits comfortably around your finger - not too tight and not too loose.
  • Use a pen to mark the point where the end of the string or paper overlaps itself.
  • Lay the string or paper against a ruler and measure the length in millimetres (mm) from its end to the point you marked with pen.
  • This measurement is your finger circumference. Use it to find your perfect ring size using our ring size chart.


  • Always double-check your measurements for accuracy!
  • Your finger size can fluctuate slightly during the day, over time, and depending on the temperature. If measuring your actual finger, we suggest doing so in the afternoon when your hands are warm for the best results.


  • If your measurement falls between two ring sizes, we suggest choosing the larger size (or half size, if available) to ensure a comfortable fit.
  • Ensure that you measure the exact finger you intend to wear your new ring on (or a ring that you wear on the same finger). Your ring size will vary between your fingers as well as your hands!
