Helpful Hints
- Our dominant hands are generally slightly larger — make sure you measure the right finger on the correct hand!
- Rings with wider bands will fit a bit tighter. If you plan to measure one of your rings, try to measure one with a similar width as the ring you want to purchase.
- Make sure the finger is at normal body temperature — fingers can shrink or expand when hot or cold.
- Your fingers tend to change size throughout the day — the best time to measure your finger is at the end of the day.
- If your knuckle is bigger, take 2 measurements and choose a size in between — rings need to fit over the knuckle but not be too loose or it will shift around.
