After you have selected your ring it is important that you provide us with the correct ring size for you or the person you are giving the ring to. This enables us to have the “ring sized” and to provide you with perfect fitting jewellery!

 

How To Measure Your Finger for a Ring Size:

First Method – Take a piece of string or a thin strip of paper. Wrap it around the base of the appropriate ring finger. Use a pen to mark the point where it overlaps, forming a complete circle. Measure the length from the starting end of the string/paper to the pen mark, in millimeters. You will then have the circumference measurement (column 2) of your finger in millimeters, and can then use the ring size conversion chart given on this site to work out your ring size (column 3).

Second Method – Measure the inside width (column 1) of a ring you currently have and use this as the ring size (column 3).

Third Method – Visit your local jeweller, and ask them to size your finger for you. If you are buying the ring for someone else, take one of their rings and ask the jeweller to size their finger based on the ring.

Our UK Ring Sizes use British Standard which uses alphabetic letters for each 1.25mm of ring circumference with half sizes in between.

When measure the finger:

  • It is a good idea to measure the finger at the end of the day, when the finger is at its largest
  • Do not measure when the finger is cold, as this will make it unusually small.
  • Do not measure your finger after exercise as you may be dehydrated and thus slightly smaller than normal.
  • Avoid measuring ring size during menstrual cycles, as water retention may cause slightly larger fingers.

Bear in mind that finger sizes change throughout the day.
