Ring Size Guide
Find Your Ring Size
Aurilyn rings use standard sizing. If you're between sizes, we recommend sizing up — and remember several of our styles (Spiral Twist, adjustable designs) fit a range of sizes.
Method 1: Measure a ring you own
Take a ring that fits the intended finger well and measure its inside diameter in millimetres with a ruler, then match it below.
| Inside diameter | AU/UK size | US size |
|---|---|---|
| 16.5 mm | L | 6 |
| 17.3 mm | N | 7 |
| 18.1 mm | P | 8 |
| 19.0 mm | R | 9 |
Method 2: String and ruler
- Wrap a strip of paper or string snugly around the base of your finger.
- Mark where it overlaps, then measure the length in millimetres — this is your circumference.
- Divide by 3.14 to get your diameter, and match it in the chart above.
Tips for accuracy
- Measure at the end of the day, when fingers are at their largest.
- Avoid measuring when your hands are cold.
- If your knuckle is noticeably larger than your finger base, size for the knuckle.
