1 - The easiest way: Measure an existing ring to find out its size

If you already have a ring (ideally of the same or a similar brand) that fits perfectly on the same finger:

      • Place the ring on a ruler and measure the inside diameter in millimetres.

      • Make sure this measurement is taken at the point where the ring is widest.

      • Consult the size guide after calculating the ring's circumference (a little math reminder: to obtain the diameter of a circle, divide the circumference by Pi or 3.14. Conversely, multiply it by the diameter to obtain the circumference). Conversely, multiply it by the diameter to obtain the circumference).

    2 - The easiest way: Measuring an existing ring with Ringsizer

    We discovered this app that calculates your ring size simply by placing the existing ring on the phone screen: Ringsizer.

    All you have to do is download the app, place the ring on your phone and then read your size ring is magic!

    3 - Direct measurement or string method

    Take a piece of string, wrap it gently around the finger where you plan to wear the ring, and mark the length. 

        • Make sure the measurement is comfortable, neither too tight nor too loose. The right ring size is the one that allows you to put the ring on without difficulty, with slight resistance at the joint, but the ring must also be able to turn on the finger.  

        • Lay the string flat and measure its precise length on a tape or ruler.

      Then use a conversion table to translate your finger length in millimetres into a standard ring size. These tables are easy to find and will give you an accurate match. If your measurement isn't right, go up a size.

      There are a few things to bear in mind:

          •  Check the width of the ring Width can influence the ring size you choose. Wide rings tend to be more fitted, so if you're going for a larger ring, consider a slightly larger ring size. Usually one size is enough, but for a very wide ring that covers the entire phalanx, 2 sizes are sometimes necessary.
          • Take into account the material of the ring Precious metal rings, such as gold or platinum, tend to be heavier than silver or stainless steel rings. Heavier rings may require a slightly larger size for optimum comfort. 
          • Pay attention to conversions and ring size equivalents: In different countries, ring size measurement systems vary, sometimes making the choice complex: USA, France, Italy, Japan, it's all a bit confusing. A ring size chart can be particularly useful in simplifying this process. This chart gives an overview of the equivalences between the different sizes. In the European system, sizes are generally expressed in millimetres, corresponding to the circumference of the finger. So a European ring size of 52 would be equivalent to 52 cm, and will be close to a ring size 6 in the USA.
          • Measure the right finger Measure the finger of the hand on which you want to wear the ring, as measurements can vary from one hand to another. 
          • Watch your finger temperature Try to measure your finger when you are at a normal body temperature, as our fingers can swell a little in the heat. It is therefore advisable to avoid taking measurements when your finger is either hot or cold.
          • Time of day It is best to measure your finger at the end of the day when fingers are generally a little larger. If measurements vary according to the time of day, we recommend choosing the largest ring size.
          • Joint size If your knuckle is significantly larger than the base of your finger, measure the knuckle as well and choose a ring size that allows you to slip it on easily.

        4 - Have your finger measured by a professional jeweller or use a ring gauge

        5 - The safest thing to do: Try on the same ring or another ring in the brand's boutique.

         

        Bear in mind that the advantage of buying a second-hand ring from a major brand is that it's easy to go and try on the ring or a similar one in your nearest boutique, or even visit their website. Look for the size guides provided by the specific brand you're considering, or better still, visit the boutique.
