Find Your Perfect Ring Size
Use one of the methods below to find your ring size. Measurements should be taken in millimeters. For the most accurate result, measure your finger at the end of the day when your hands are at a normal temperature.
Method 1 – Measure an Existing Ring
- Choose a ring that fits the intended finger comfortably.
- Measure the inside diameter of the ring from one inner edge to the opposite inner edge.
- Do not include the metal edges.
- Compare the result with the “Inside Diameter” column in the table.
Method 2 – Measure Your Finger
- Wrap a thin strip of paper or non-stretch string around the base of your finger.
- Keep it comfortably snug, but not too tight.
- Mark the point where the ends meet.
- Measure the length in millimeters.
- Compare the result with the “Finger Circumference” column.

Important Tips
- Our ring sizes are US sizes.
- Measurements in the table are approximate.
- If your measurement falls between two sizes, choose the larger size.
- Measure your finger at least two or three times for accuracy.
- Finger size may change depending on temperature and time of day.
- Wider ring bands may feel tighter than thin bands.
- If you are unsure, we recommend having your finger professionally measured by a local jeweler.
