If you don't have a ring of the size you're looking for, this will help you discover how to find the correct size.
- Take a piece of string, piece of paper (no wider than 1.4cm or ½ inch), as this will help you to be accurate.
- Wrap it around the base of the finger you would like to measure.
- Use a pen to mark the point on the string or paper where it overlaps. The overlap will form a complete circle.
- Take a ruler and measure the length of the string or paper from the starting end, to the end you marked with the pen.
- Finally, use this measurement and compare it against the chart below to determine your ring size.
