Ring Size Tips

  1. Measure the Correct Hand: Our dominant hands are generally slightly larger, so make sure you measure the right finger on the correct hand!
  2. Consider Band Width: Rings with wider bands will fit a bit tighter. If you plan to measure one of your partner's rings, try to measure one with a similar width to the ring you want to purchase.
  3. Check Temperature: Make sure the finger is at normal body temperature—fingers can shrink or expand when hot or cold.
  4. Time of Day Matters: Your fingers tend to change size throughout the day. The best time to measure your finger is at the end of the day.
  5. Account for Knuckles: If your knuckle is larger, take two measurements and choose a size in between. The ring needs to fit over the knuckle but not be too loose or it will shift around.
  6. When in Doubt: If you don’t know your partner’s ring size, selecting one of the standard ring sizes is your best choice. The average ring size for women is 6 to 7, and the average ring size for men is 9 to 10.
