Matters needing attention when measuring ring size:
1, test several times.
Because the measurement method we use is very daily, and we don't use very sophisticated instruments to ensure the accuracy of the results, so we'd better measure several times according to the same steps and take the average. If the results of several measurements are quite different from the usual results, then discard these values decisively and average the remaining results.
2. Pay attention to the measurement time.
Everything in the world will follow the principle of "expansion with heat and contraction with cold", and fingers are no exception. When buying a ring in winter, the size of the ring should be about half, so that in summer, the finger will swell and the ring will not become too tight.
