Find Your Perfect Ring Size
Getting the right fit is easy! Use one of these quick methods:
Option 1: Measure a Ring You Already Own
- Choose a ring that fits the finger you'll wear it on.
- Measure the inside diameter in millimeters with a ruler.
- Use the chart below to find your US ring size.
Inside Diameter (mm)
- 15.7 mm = size 5
- 16.5 mm = size 6
- 17.3 mm = size 7
- 18.1 mm = size 8
- 18.9 mm = size 9
Option 2: Measure Your Finger
- Wrap a strip of paper or string snugly around your finger.
- Mark where it overlaps and measure the length in millimeters.
- Match the measurement to the circumference in a ring size chart.
Tips for a Perfect Fit
- Measure at the end of the day when your fingers are warm.
- If you are between sizes, order the next size up.
- Wider bands may fit slightly tighter.
