Ring Sizing
How To Measure Your Ring Size
Follow these directions to measure your finger. They will give an approximate guide to establish your ring size.
- Find a piece of string or strip of paper no wider than 1.4 cm (½ inch).
- Wrap it around the base of the appropriate finger.
- Use a pen to mark the point on the string/paper where it overlaps, 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.
- For the most accurate reading using this method measure the finger at the end of the day when the finger is the largest.
- If the measurement is in-between sizes, choose the next size up.
