How to measure your wrist
Wrap a flexible measuring tape just above the wrist bone.
If you don't have a tape measure handy, you can use a strip of paper and mark it where it overlaps. Then lay the strip flat to measure up to the mark using any ruler.
If buying a bracelet as a gift, you could measure the watch's bracelet of the person you are buying for.
Add a little - between 1 to 2 cm.
This will be the ideal length for your bracelet.
The reason the bracelet need to be a little longer, is because the wrist tends to expand when you are hot.
