For rings, you can measure your finger size by yourself.
At TimJeweler, we offer extra small to extra large bracelet sizes (US):
5.5 inches for extra small wrists(kids, teenager);
6.5 inches for small wrists;
7.5 inches for regular wrists;
8.5 inches for large wrists;
9.5 inches for extra large wrists.
HOW TO MEASURE
STEP 1: Measure your wrist with a flexible tape measurements or a strip of paper just below the wrist bone, where you would normally wear the bracelet.
STEP 2: If you are using a plain strip of paper, mark your size with a pen or pencil then use a ruler to measure the length, and give your wrist a loose fit to move around.

The bracelets are great, I just guessed the wrong sizes for the wrists. But other than that I will aay the quality of the craft in the bracelets are awesome!!!! My only half attempt at a complaint is that the polish that was sent along with the bracelets was not in vein lol. The metal plates with the engravings as well as the clasp are both easily smudged by fingerprints.
