Size guide
Here’s a ring size guide that will help you determine the right size for your ring, including US and UK equivalents, as well as the corresponding inner diameter (in millimeters). Ring sizes can vary slightly depending on the brand, but this chart should give you a general idea.
How to Measure Your Ring Size
1. Use a Ruler
You’ll need a ruler to measure across the widest part of your finger (often this is the knuckle). The measurement should be taken from one side of your finger to the other, passing through the center (making sure it goes through the widest part of the finger).
2. Measure the Inside Diameter:
- Place the ruler directly across the inside of your finger.
- Make sure it is straight and level so that you're measuring the full width at the point where the ring will sit.
- Record the measurement in millimeters (mm).
3. Compare with Ring Size Chart:
Once you have the diameter measurement, you can compare it to the ring size chart to find your ring size.
Tips for Accurate Measurement:
- Measure when fingers are at a normal temperature: Fingers shrink when cold and expand when warm.
- Consider the width of the band: Wider bands may require a slightly larger size for comfort.
- If you're in between sizes: We usually encourage you to size up when unsure.
