Is it better to tighten or loosen the ring
When wearing a ring, it is not suitable to be too loose or too tight. Loose rings are prone to falling off, while tight rings can cause pressure on fingers, leading to poor blood circulation. When choosing a ring, you can choose a slightly loose ring. One is to leave space for the growth of finger size in the future, and the other is that the finger size of the human body varies slightly in different seasons, with slightly larger sizes in summer and slightly smaller sizes in winter. It is best to follow the principle of being loose rather than tight.
What to pay attention to when measuring ring size
1. It is recommended to choose a thin rope or paper without elasticity for measuring PROPS, and not to use cotton thread or rubber bands.
2. When reading values, the line of sight should be parallel to the scale being read to avoid errors caused by different angles, preferably accurate to 0.1mm.
3. Due to the easy thermal expansion and contraction of finger blood vessels, there may be deviations in measurements at different temperatures and seasons. Measurements may be tighter in summer and looser in winter. It is recommended to take the average of multiple measurements at different times.
4. There are different versions of the ring size comparison table, such as international version, mainland version, Hong Kong version, etc. Different versions correspond to different ring sizes. When purchasing, it is important to be clear which version of the ring size chart the brand is using.
