How do I know my finger size?
1ère method:
How to proceed Print the size chart on your printer Check that the 10cm indicator measures 10cm on your sheet of paper.
Place a ring that looks good on you (a wedding ring for example) on the sheet of paper.
When the inside diameter of your ring exactly matches the inside diameter of a ring on the sheet of paper, you have found the size of your finger.
You also have the option of measuring with a caliper the inside diameter of a ring that fits you well. By equivalence you know immediately what your finger size is.
