THE FIT FORMULA
If you prefer your bracelet to sit tightly against your wrist, add only a small amount to your wrist measurement.For a more relaxed fit, add a bit more. Just be cautious of adding too much length, as the bracelet might then become too loose.
For a more visual approach, do the following:
Grab a flexible measuring tape, a string, or a strip of paper and wrap it around your wrist.
Mark where the end meets the rest of the string or paper.
Lay the string or paper flat next to a ruler and measure the length up to the mark. Refer to the size chart above.
