Checklist: Determining the ring size

  • Because of swellings, finger tend to be slightly thicker in the evening and generally in hot temperatures
  • As hands swell less in colder climates, it is possible that a ring which fits in the summer will be too big in the winter months
  • A ring’s perceived fit depends on its shank’s width: If the shank is relatively broad, a bigger ring size might be necessary and vice versa

Changing the ring size afterwards
