You can find out your ring size by measuring the circumference of your finger at the knuckle.

To get that number take a small strip of paper, wrap it around your knuckle and make a mark where it overlaps. Measure the paper up to that mark to find the circumference of your ring and convert it using the chart below.

If you are between two sizes, take into consideration the season (cold weather usually means skinnier fingers), your knuckle-to-finger ratio and preferred fit, as well as how often you plan on taking it on and off, etc.

Some of our rings are U shaped (with a flat top), which makes them a bit more forgiving in the way they size. They are usually available in 3 sizes S: 4-5, M: 6, L: 7-8. If you are in between sizes, we recommend you choose the smaller one, as this U shape leaves a bit of extra room and loose rings tend to get misshapen easier.

If you are ordering a 14K ring or a custom piece and want to try the fit to be completely be sure of the size, you can request returnable a set of ring samples to be mailed to you for free, please email us at online@martapia.com for more details.
