How to measure (4 steps): Step 1 — Take a long rope or piece of paper and circle around your finger. Step 2 — Make the rope fit tightly to your finger, pressing to avoid being too loose or too tight. Step 3 — In the case of long strings or paper, mark the junction piece. Step 4 — Lay out the long rope or the paper. Measure the length was used to circle the piece. It is recommended to take the middle value after multiple measurements.
