Quick Measurement Tips:
- Wrap a thin strip of paper or thread around the base of the finger you want to measure.
- Mark the point where the paper meets to form a complete circle.
- Measure the length of the marked paper against a ruler (in millimeters) to get the Circumference, then match it to the table above.
