The following chart will be helpful for you to get the exact size of your ring. You can either make use of a small piece of string/paper or a tape to measure the area that will be occupied by the ring. When it becomes a complete circle, make a mark on the string. This will be helpful for you to compare with the chart that is mentioned below. For extra width, you can add another size to accommodate.
Step 1
Take a thin thread or strip of paper. Wrap the thread or paper around your finger. Mark the meeting spot of the thread/paper’s end.
Step 2
Measure the length of the thread/paper on a scale. Use the following chart to determine your ring size.
