How to Determine Your Ring Size

Method 1 — Use a ring you already own

Take a ring that already fits the intended finger (or borrow one, if this is a surprise engagement or a gift). Measure the inside diameter of the ring in millimetres — straight across the widest point of the inside of the band — and enter it into the calculator above, or match it in the chart below.

If the measurement falls between two sizes, order the larger size.

Please note:

• Consider band width. The wider the band, the tighter it may feel — you may need to go up by a half size.

• These guides serve as a reference — contact us if you need any help!

Finding Your Bracelet Size

Size your cuffs and bangles to fit snugly, and your link and chain bracelets with a touch of breathing room to allow for movement.

1. Grab a tape measure, length of string or strip of paper.

2. Wrap it around the wrist you’ll wear your bracelet on. Mark the place where it joins. Creating a stack? Measure where on your arm you’ll wear each bracelet.

3. Lay your string or paper strip on a flat surface and use a ruler to measure the length up to the mark. You will find your equivalent size in centimetres on the bracelet product page.
