Size guide
Finding the right fit matters for comfort and for avoiding a return. Use the guide below to determine your size for our 925 sterling silver rings, necklaces and bracelets.
Ring Size Guide
Loretana fixed-size rings come in four sizes: 16.5, 17.3, 18.1 and 18.9 mm. The number is the inner diameter of the ring in millimetres, and each one matches a US size exactly. A 17.3 mm ring has an inner diameter of 17.3 mm, which is US 7.
Several designs are open adjustable bands with no size to choose. For the full conversion to EU and UK sizes, and for rounding from a Baltic size, see our ring size guide.
Method 1 — measure a ring you already own
Take a ring that fits the intended finger well. Measure the inner diameter across the widest point with a ruler. Match that measurement in millimetres to the nearest size below.
Method 2 — measure your finger
- Wrap a strip of paper snugly around the base of the finger.
- Mark where the paper completes the circle.
- Measure from the beginning to the mark with a ruler. This is your circumference in millimetres.
- Divide the circumference by 3.14. The result is your inner diameter in millimetres.
Example: a circumference of 53 mm ÷ 3.14 = 16.9 mm. That falls between two sizes, so take the larger — 17.3 mm (US 7).
Loretana Ring Size Chart
| Loretana size (mm diameter) | Circumference (mm) | US size | EU (approx.) |
|---|---|---|---|
| 16.5 | 51.8 | 6 | 52 |
| 17.3 | 54.4 | 7 | 54 |
| 18.1 | 56.9 | 8 | 57 |
| 18.9 | 59.4 | 9 | 59 |
Every product page shows both numbers, for example 17.3 mm (US 7). EU equivalents are approximate.
Tips for the right fit
- Comfort first: the ring should be snug enough not to slip off, but pass over the knuckle without force.
- Mind the knuckle: if your knuckle is noticeably larger than the base of the finger, measure both and choose a size in between.
- Timing matters: measure at the end of the day, when your hands are warm. Fingers are smaller in the morning and in cold weather.
- Dominant hand: fingers on your dominant hand are usually slightly larger.
- Between sizes? Choose the larger one.
- Measure twice. Three times is better.
Still unsure? Email your measurement to info@loretana.com and we will confirm your size before dispatch.
