Ring Size Guide

You can measure your finger in two different ways:

  • Use a measuring tape no wider than 2cm. Do not use a piece of string or thread as this will follow the contours of your finger too closely and record an incorrect size.
  • Measure the circumference of your finger by wrapping the measuring tape around your finger, ensuring it slides easily over the knuckle. Using a pen, mark the tape at the point where it overlaps.
  • Now measure the length in millimetres from the start of the tape to the pen mark, using a ruler.
  • Compare this measurement against the chart below to see whether we stock a ring to fit your size

    Top tip: always measure your finger at room temperature. If the conditions are too cold, your finger will be smaller; if too hot, your finger will be larger.

Otherwise, if you have a ring that already fits the same finger, you can measure the diameter of it using a ruler to measure across the inside edge of the ring in millimetres.

Compare these measurements against the chart below to determine whether we stock a ring to fit your size.
