Taking a wrist measurement
For a perfect fit, measure your wrist at its broadest point – which means you should measure AT the place where your wrist bone is. This allows your bracelet to comfortably move either above or below your wrist bone.
Using a flexible tape measure, place it around your wrist at the place where your wrist bone is.
If you don't have a tape measure handy, use a strip of paper or thin string, and mark it where it overlaps on your wrist. Then lay the strip flat to measure up to the mark using any ruler.
This is the measurement you should give me. I then adjust the size of the bracelet based on whether you like a snug, standard or loose fit.
Measuring your wrist properly is key to getting the perfect fit.
