The simplest way to work out your ring size is to measure a ring you already own for a ring that will go on the same finger (note that fingers on different hands can be different sizes).
To do this you just take a ruler and measure straight across the inside of the ring from inside edge to edge. Take the diameter measurement in inches or mm, and then use our measurement-conversion chart to find your ring size.
If you don't have a ring of the same size:
- Take a piece of string or paper and rap it around the base of the finger to measure.
- Use a pen to mark the point on the string or paper where it overlaps.
- Take a ruler and measure the length of the string or paper from the starting end, to the end you marked with the pen.
- Use this measurement and compare it against the chart below to determine your ring size.
