Ring Size Guide
Finding the perfect ring size is crucial for comfort and security. Use this guide to determine your ring size or that of a loved one.
How to Measure Your Ring Size
Method 1: Use a Ring Sizer
The most accurate method is to use a professional ring sizer. You can order one from our shop or visit a local jeweler.
Method 2: Measure a Ring You Already Own
- Find a ring that fits the desired finger comfortably.
- Place the ring over the circles on the chart below.
- Match the inside edge of the ring to the circle nearest in size.
- If the ring falls between two sizes, choose the larger size.
Method 3: Measure Your Finger
- Wrap a piece of string or paper around your finger where the ring would sit.
- Mark where the string or paper overlaps to form a complete circle.
- Measure the length of the string or paper in millimeters.
- Use the chart below to find your ring size.
Tip: Measure your finger at the end of the day when your fingers are warmest. Avoid measuring when your hands are cold as your fingers may be slightly smaller.

Additional Tips
- Your dominant hand may be slightly larger, so measure the specific finger you plan to wear the ring on.
- Wide bands may fit more snugly than thin bands. If choosing a wide band, you may want to order a half size larger.
- If your knuckle is significantly larger than your finger's base, measure both and choose a size in between.
