Vyvo uses the European sizing system for our rings:
The BioSense Ring is available in sizes with internal diameters of 16.5 mm (0.65 in), 17.4 mm (0.69 in), 18.2 mm (0.72 in), 19 mm (0.75 in), 19.9 mm (0.78 in), 20.7 mm (0.81 in), 21.5 mm (0.85 in), and 22.3 mm (0.88 in).
How should the finger size for the Vyvo Ring be measured?
We recommend printing the Vyvo tape measure at full size (no printer scaling). Wrap it around your finger, note the measurement, and consult the Vyvo Ring size table. If the measurement is between two sizes, choose the larger size.
Please note: the Vyvo tape measure is for reference only, and Vyvo is not responsible for any errors that may occur from measuring your finger.
Follow these steps as shown in the video below:
- Download the Vyvo BioSense Ring Size Guide and print it in 1:1 scale. Ensure the “Scale to fit” option is unchecked in the print dialogue box. The scale is fundamental to ensure that the sizes stay true.
- Cut out the tape measure print on the first page following the guides.
Use a ruler to verify the printed scale is correct. Have a comparison ring ready. This should be a ring that you wear on the same finger as you intend to wear the Vyvo ring. - Wrap the printed Vyvo tape measure around your finger. Note the measurement, and consult the Vyvo ring size table, included in the second page of the Vyvo BioSense Ring Size Guide, to determine your ring size.
If your measurement is between two sizes, choose the larger size. - You can position your ring over the circles of the conversion chart to determine which one matches your size. The diameter should correspond exactly with the diameter of your ring.
- Now you can purchase your BioSense ring, by selecting the correct size. Please note that Vyvo uses European sizing.
Vyvo cannot be held responsible for any errors that occur as a result of measuring your finger.
