Don’t pull it tight. Mark where it overlaps with a pen. Lay it flat and measure the distance between the marks. Check the circumference column in our size chart to find your size. Measuring tips - Measure twice to be sure. - For accuracy; measure in the afternoon when your hands are warmer. - Measure the index finger on the hand where you plan to wear the ring; remember; the same finger on the other hand might be a different size. The index finger is recommended because it makes the smart ring most usable; ensuring optimal functionality and ease of access. - If your hands tend to swell; consider sizing up. - Size 8 Inner circumference 18.3mm 6g - Size 9 Inner circumference 19.4mm 6g - Size 10 Inner circumference 20.2mm 6g - Size 11 Inner circumference 21mm 6g - Size 12 Inner circumference 22mm 7g - Size 13 Inner circumference 22.8mm 7g
