Determining Your Ring Size

1. Find a piece of string or strip of paper.

2. Wrap it around the base of your appropriate finger. Make sure the paper fits snugly.
You should be able to slip it over your knuckle.

3. Using a pen - mark the point on the string/paper where it overlaps forming a complete circle.

4. Measure the length from the starting end of the string/paper to the pen mark using a ruler with a millimeter measurement.

5. Check this measurement with the chart below to determine your ring size.

To get the most accurate reading, make sure your hands and fingers are warm, preferably at room temperature.
