14K Gold Organically Shaped Emerald Ring

If your size falls between two sizes, we recommend choosing the larger one. *Guto uses US ring sizes. Please note that sizing may vary slightly between brands. It's best to measure your actual ring or finger for the most accurate fit.

Two Quick Ways to Find Your Guto Ring Size

Method 1: Measure the Inner Diameter of an Existing Ring

You can also use a smartphone app to measure your ring. Simply place the ring on your phone screen and use the slider to determine the inner diameter or US ring size. We tested the Jason Withers Ring Sizer app, which works well with Guto rings (US sizing). We recommend using a relatively flat ring for best results.

The app is free to download on both iOS and Android.

Refer to the chart above to find your ring size.

Method 2: Measure Your Finger Circumference

Use a tape measure to wrap around your finger snugly. If you don’t have a tape measure, you can use string, dental floss, or even a strip of paper and then measure it with a ruler.

Make sure to measure your finger at a normal size. Cold weather may cause your fingers to shrink slightly, while drinking alcohol, exercise, hot weather, and swelling can make your fingers swell.

If your knuckles are particularly large, you may need to choose a larger ring size to fit over the knuckle.

Refer to the “Finger Circumference (mm)” column in the chart above to find your ring size.
