Our Tips
- Temperature and time of day are important. Try not to measure your hands when they're too hot or too cold!
- It's best to take your measurements in the evening when your hands are at their largest. If you find yourself between two ring sizes, always go with the larger one.
- If you (like a lot of us) have knuckles larger than the base of your finger, consider going up a size.
- If you are purchasing a ring that has a wider band, we advise going one size up.
