Helpful sizing tips
- Fingers on a dominant hand are generally slightly larger than on non-dominant hands— make sure you measure the right finger on the correct hand!
- Rings with wider bands will fit a bit tighter. Consider selecting one 1/4 to 1/2 size up from your normal ring size.If you plan to measure one of your partner's rings, try to measure one with a similar width as the ring you want to purchase.
- For stacking rings: for a more comfortable fit, consider selecting one 1/4 to 1/2 size up from your normal ring size.
- 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 the end of the day.
- If your knuckle is bigger, take 2 measurements and choose a size in between — ring needs to fit over knuckle but not be too loose or it will shift around.
