BRACELET
We have already listed some steps for you to choose the right size for bracelets.
For men:

Generally, men start at 7″ for small wrists, 8″ for medium wrists, and 9″ for large wrists. Typically, the average male has an 8″ wrist.

For women:
Start at 6″ for small wrists, 7″ for medium wrists, and 8″ for large wrists. Typically, the average woman has a 7″ wrist.

Step 1: Measure your wrist with a flexible tape measurement or a strip of paper just below the wrist bone, where you normally wear the bracelet. (Please note that if you are using a plain strip of paper, mark your size with a pencil or pen, then use a ruler to measure it.)

Step 2: Add one inch, or 2.5 centimeters, to this measurement to get the final length of your bracelets. (Please note that a bracelet is perfectly sized when you measure your wrist tightly and add 2 or 3cm. If you are between sizes, ask yourself how you like to wear your bracelet. If you wear it tightly, choose the smaller size. If you like to wear it loosely, take the next size up.)

RING
