Rings Size Guide
Sizing can be tricky. If your knuckle's larger than the base of your finger, split the difference between two sizes. You need a fit that slides on smoothly but stays put. So, take two measurements and meet somewhere in the middle.

|---|---|
| 2 | 13.3 |
| 2.5 | 13.7 |
| 3 | 14.1 |
| 3.5 | 14.5 |
| 4 | 14.9 |
| 4.5 | 15.3 |
| 5 | 15.7 |

| 6 | 16.5 |

How to Measure
Measuring Tips for a Flawless Fit
- When measuring, make sure you are at a normal body temperature; fingers shrink in the cold & expand in the heat!
- Stay cool, don't measure when you're hot! Fingers shrink in the cold and expand in the heat.
- Skip the salted rims before sizing - cocktails and swelling fingers don't mix, so you will not get an accurate measurement.
- When in doubt, size up. If you're caught between sizes, don't sweat it. Go for the larger size and enjoy a fit that's just right.

Measure Your Finger
Best Option for the solo shopper
What you'll need:
- A thin strip of paper; we recommend a 3” strip
- Pen or marker
- Ruler
Steps:
- Wrap the paper around the base of your finger, right where you plan to wear the ring.
- Make sure the paper is snug against your finger for the most accurate measurement.
- Grab that pen or marker and mark where the paper meets.
- Lay that strip flat and break out the ruler to measure the distance between your mark and the end of the strip, all in millimeters.
- Use our chart to determine your perfect fit.
