Precautions for measuring ring size
1. The best measurement time is in the evening. Affected by thermal expansion and contraction, the finger size will be smaller in the morning and larger in the evening.
2. Self measurement requires multiple measurements and taking the average.
3. The size comparison table for different brands is different, and when measuring, the size table provided by the brand should be compared.
4. Suggest taking measurements at a jewelry store for more accurate measurements.
