The best way to measure your fingers is by a jeweller using a ring sizer. If this is not available to you then use the guide below to estimate your size.
- Find a piece of string or strip of paper no wider than 14 mm
- Wrap it around the base of the finger.
- Use a pen to mark the point on the string/paper where it overlaps, and forming a complete circle.
- With a ruler, measure the length from the starting end of the string/paper to the pen mark.
- Use the chart below to determine your UK ring size.
Here are some tips to make your ring size measurement more accurate:
- After sliding the ring sizer on, make sure it slides off fairly easily over the knuckle.
- Don't measure cold fingers. This is when fingers are their smallest
- For the most accurate reading, measure the finger at the end of the day when the finger is the largest
- If you have a ring that fits you can measure it across the widest and email us the internal measurements in mm and we will be happy to help determine the size.
