If you're right between sizes, we suggest to choose the bigger size.
* Aeterna Jewelry uses US ring sizes, but please note that ring sizes may vary slightly between brands. It's best to confirm against actual ring/finger measurements.
Two ways to quickly find your Aeterna ring size
Method 1: Measure the inside diameter of a ring you already own
You can also use a smartphone app to measure a ring you own by placing it on your phone screen and using a slider to determine the inner diameter or US ring size. We have tested the app "Ring Sizer by Jason Withers" and it works well with Aeterna rings (which are sized in US sizes). It's preferable to use a relatively flat ring.

Check the table above to find your ring size.
Method 2: Measure the circumference of your finger
- Measure your finger by wrapping around it snugly with measuring tape. If you don't have measuring tape, you can use string/floss or even paper, and measure against a ruler
- Make sure your fingers are at a normal size when you measure them. Fingers shrink a bit in cold weather, and they swell after you've had alcohol, after you've exercised, when you're in hot weather, and when you're generally bloated
- If your knuckle is particularly big, you may want to choose a bigger ring size so that the ring can fit over the knuckle
