Ring Sizing Guide
Finding the right ring size ensures a comfortable fit and keeps your jewelry secure. Fingers can slightly change size throughout the day due to temperature, hydration, and activity level, so it’s important to measure carefully.
How to Measure Your Ring Size
Option 1: Measure a Ring You Already Own
-
Choose a ring that fits the intended finger comfortably.
-
Measure the inside diameter of the ring in millimeters (mm).
-
Match the measurement to a ring size chart to determine your size.
Tip: Make sure you’re measuring the inside edge to inside edge — not the outer band.
Option 2: Measure Your Finger
-
Wrap a thin strip of paper or a flexible measuring tape snugly around the base of your finger.
-
Mark where the ends meet.
-
Measure the length in millimeters — this is your finger’s circumference.
-
Compare that number to a standard ring size chart.
Tip: The strip should be snug but not tight — it should slide over your knuckle comfortably.
Ring Size Conversion (US Sizes)
| US Size | Inside Diameter (mm) | Circumference (mm) |

| 6 | 16.5 mm | 51.9 mm |
| 7 | 17.3 mm | 54.4 mm |
| 8 | 18.1 mm | 57.0 mm |
| 9 | 18.9 mm | 59.5 mm |
| 10 | 19.8 mm | 62.1 mm |
(If you’re between sizes, we recommend sizing up for a more comfortable fit.)
Helpful Sizing Tips
-
Measure your finger at the end of the day, when it’s slightly larger.
-
Avoid measuring when your hands are cold — fingers shrink in lower temperatures.
-
Wider bands tend to fit more snugly, so consider going up half a size for thicker rings.
-
Your dominant hand is usually slightly larger — measure the exact finger where you’ll wear the ring.
If you're unsure between two sizes, choosing the larger size is typically the safest option for comfort.
