SIZE GUIDE
How to find your Nos Une ring size?
Here are some easy tricks to find your size without the need for special tools.
1. There are two methods:
-
The most reliable is using an existing ring:
- Measure the internal diameter in millimeters of a ring you already own that fits you well (as shown in the video below).
- Use that measurement to find your size in the table below. If you have any doubts, send us a photo at nosune.shop@gmail.com

-
With a measuring tape or a strip of paper:
- Wrap a strip of paper or a measuring tape around your finger.
- Pull it snug and mark the point where it overlaps.
- Take a ruler and measure the length of the strip in millimeters for greater precision.
- Check our size chart to find your measurement.
2. Additional Tips
- Measure in millimeters and start from zero.
- If it's a gift: the most common sizes are 11, 12, 13, and 14.
- Measure at the end of the day for greater accuracy.
