LUXQUSITE offers a free Hong Kong version ring size measuring tool.

The usage method is as follows:

1. Slip it on your finger and pull it slightly tight.

2. The number indicated by the arrow is your ring size.

*Note* Multiple sizes can be adjusted on the same finger. Try them on repeatedly to find the most accurate size. When measuring the ring size, prioritize a comfortable size that won't slip off. Due to thermal expansion and contraction, in summer, the ring should feel "slightly tight" when worn, while in winter, it should be able to rotate slightly without falling off.
