Ring Sizing Guide
Method 1 — Measure your finger
- Wrap either a strip of paper or string around your finger where you would like the ring to sit
- Make sure that the strip of paper or string is tight to your finger to find the best fit
- Mark the spot where the string or paper meets and then measure that against a ruler IN MM (these are the small ticks in between CM on a ruler)
- Use the chart below to determine your ring size.
- If you are in-between sizes, we recommend sizing up.

Tips for measuring fingers
-
Cold weather causes your fingers to shrink, we recommend measuring when your fingers are warm.
-
Fingers swell throughout the day and are largest at then end of the day, so we recommend measuring them at this time.
-
Did you know alcohol and salt can cause your fingers to swell? Make sure to measure them before consuming any alcohol or high salt content foods.
