How to Find the Right Ring Size

Choosing the correct ring size is essential for comfortable wear. Accurate sizing helps avoid future adjustments and ensures that your ring fits perfectly.

Our Recommendation — Have Your Ring Size Measured by a Jeweler

The most accurate way to determine your ring size is to have it measured by a jeweler using professional sizing tools. If possible, we recommend checking your ring size before placing your order. The measurement only takes a few minutes and helps prevent ordering the wrong size.

Measuring an Existing Ring

If you already own a ring worn on the desired finger, you can measure its inner diameter with a caliper or have the size determined by a jeweler. Alternatively, you can use a ring size app on your smartphone that helps determine the correct size based on an existing ring.

Important Notes

Measure your finger preferably at the end of the day, when it has reached its natural size. Avoid measuring directly after physical activity or in very hot or cold temperatures, as these conditions may affect the result. If your measurement falls between two sizes, we recommend choosing the larger size. When in doubt, we recommend having your size professionally measured by a jeweler.
