Flow size chart

 

The Flow is designed to fit comfortably on the finger, which is why three sizes are available.

You can choose between SMALL, MEDIUM and LARGE choose.

Please measure the circumference of your index finger at the top joint:

If the circumference smaller than 4.7 cmplease choose SMALL. If it is larger than 5.2 cmplease choose LARGE. For all index finger circumferences in between (4.7cm to 5.2cm), please choose MEDIUM.

Tip:
If you don't have a flexible measuring tape, you can simply take a thread, shoelace or cord, wrap it around the joint and then read off the length in centimeters using a ruler, triangle or folding rule.
