Our rings are sold in US sizes. Most designs run from US 5 to US 9, and a few are also available in US 10 and 11 — the sizes actually stocked for each design are shown in the size selector on its product page.

Where a product page also quotes a circumference next to the US size, that figure is the maker's own measurement for that design and may differ by a fraction of a millimetre from the standard table above.
How to measure your size
Wrap a strip of paper or a length of thread around the base of the finger you'll wear the ring on, mark where it meets, then measure the length in millimetres with a ruler. That measurement is your inner circumference — find the closest match in the table above.
For the most accurate result, measure at the end of the day when your fingers are at their largest, and avoid measuring when your hands are cold. If your measurement falls between two sizes, we'd generally suggest the larger one.
Bracelets and necklaces
Chain and bracelet lengths are listed in each product's description, including any adjustable extender. If you're between two lengths, most people find a slightly looser fit more comfortable for everyday wear.
