Tips

Beware!

The thickness of fingers changes during the day. Determine your ring size only in the evening, at room temperature (20 ºC / 68 ºF).

Borrow a well-fitting ring

If you don't have a ring, see if you can borrow one that fits. Then go to www.findmyringsize.com and in a few seconds you can determine the right size. Make sure the borrowed ring is about the same width and height (5 or 6 mm / just under 1/4") as the tweet-ring you are considering.
