Size Guide

How to choose your ring size

Once you have chosen your ring, you will want to make sure you are buying the correct size. 
To find out your ring size you can either follow the simple instructions below or email us at info@81stgeneration.com.

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