Ring Sizing Guide
Finding the perfect fit is essential for comfort and security. Use our guide to determine your ring size from the comfort of home.
How to Measure
String Method: Wrap a thin string or strip of paper around the base of your finger. Mark where the ends meet, then measure the length in millimeters and compare to the circumference column in our size chart below.
Ring Method: Place a well-fitting ring on a ruler and measure the internal diameter in millimeters. Match the measurement to the diameter column in our chart.
Printable Sizer: For the most accurate measurement, we recommend visiting a local jeweler for professional sizing. Many jewelers offer this service at no charge.

Tips for the Best Fit
- Measure in the evening when your fingers are at their largest
- Measure 2–3 times on different days for accuracy
- For wider bands (6mm+), go up half a size for comfort
- If you fall between two sizes, choose the larger size
- Temperature affects finger size — avoid measuring when very cold or hot
- Your dominant hand is typically slightly larger
- Knuckle size matters: if your knuckle is significantly larger than the base of your finger, measure both and choose a size in between
