When it comes to purchasing jewelry, choosing a ring often presents a significant challenge. Selecting the right finger size or determining the ideal size for the intended recipient can be daunting and delicate tasks. Indeed, the diversity of body shapes and preferences makes this process particularly complex. It is common to find oneself uncertain about the precise size, which adds an extra level of stress to the purchasing experience.

Measuring your finger size by yourself

Based on our experience, we strongly advise against attempting to measure your own finger, especially if you do not have the appropriate tools. It is imperative to understand that even slight variations can have a significant impact on ring size, so precision is absolutely essential.

Nothing can surpass the accuracy of the sizing tools used by a professional jeweler. Therefore, it is highly recommended to visit an expert to determine your size. By doing so, you will prevent a series of disappointments, hurdles, and complications that may arise from attempting to solve this issue yourself.

By opting for the services of a professional jeweler, you will benefit from precise and personalized expertise, ensuring a hassle-free purchasing experience and the certainty of acquiring a piece of jewelry perfectly suited to your body shape and expectations.

And how does it work at EmmanuelleGuyon.com?

We always take the time to inquire from our customers how they obtained their ring size and confirm it with them. Our business is not dedicated to mass production of jewelry; each piece ordered is custom-made. As artisans, we craft each ring according to your precise specifications, which is why we place particular importance on mutual trust in the process, so that each interaction is as satisfying an experience as possible.

A simple mistake can lead to a series of complications and unexpected additional costs. If adjustments are needed, you will have to return your ring and then visit a jeweler to obtain an accurate measurement of your finger size. Depending on the necessary adjustments, this could involve resizing the ring larger or smaller. These steps, combined, can easily take several weeks, and in the best-case scenarios, it could take about eight weeks before you can receive the corrected product, from the time you ship it until you receive it.

We place great importance on the accuracy of our exchanges to ensure the perfect fit of your ring size from the outset. Our approach is characterized by a high level of communication with our clients because we understand that every detail matters to ensure your complete satisfaction. By working together meticulously, we ensure that the measurement is taken with the utmost precision from the start, thus avoiding any inconvenience or subsequent adjustments.

How to measure your finger size

Our expert advice: if you have a particular fondness for rings and regularly acquire them, investing in a ring sizer can prove to be a wise decision, offering unmatched reliability and convenience in determining your ring size.

However, keep in mind that the final size of your jewelry can also be influenced by the width of the band. Therefore, when placing your order, please specify the type of ring sizer you have used. This way, we will be able to accurately calculate the size taking into account the width of your ring, ensuring a perfect fit and optimal comfort once your jewelry is made.

Measurement methods that do not work

Using a paper scrap to determine your ring size

There is a simple method that can be implemented, but it can have disastrous consequences. It involves wrapping a strip of paper around your finger and marking a line where the strip crosses. However, this method is prone to potential errors because the result depends on how tightly the strip was wrapped during the measurement. A slight loosening or excessive pressure of the strip at the time of marking can skew the measurement. Additionally, a piece of paper lacks the necessary rigidity to ensure optimal accuracy, unlike a professional ring sizer.

It is also crucial to consider the width of the paper used in this method and to ensure that this "paper ring" fits properly at the joints of the phalanges. This part of the finger can vary in thickness from person to person, which can affect the accuracy of the measurement.

Calculating your ring size use a ring sizer band

Just like the previously mentioned paper strip method, this trick can also be prone to inaccuracies. It involves using a printable ring sizer strip that can be found online, displaying various ring sizes. However, this method may suffer from similar shortcomings as the previous one: a ring sizer strip that is too tight or too loose will not allow for an exact measurement, and the width of the strip relative to the ring as well as the passage of finger joints can also influence measurement accuracy.

Furthermore, there are potential challenges associated with printing this famous strip. Scale or printer configuration issues may arise, leading to variations in print size and, consequently, errors in ring size measurement. Therefore, it’s important to consider these factors when considering using this method to determine your ring size.

Using another ring to determine you ring size

This third method for determining one’s ring size is also not without uncertainties. It involves directly measuring the diameter of a ring already in our possession or tracing the inner contour of a ring on a piece of paper to then measure its diameter.

Often used when wanting to gift a ring without needing the person themselves, this method may seem practical. It simply involves discreetly borrowing the ring from the concerned individual and returning it once the measurement is taken.

However, it should be noted that the reference ring may be subject to deformations over time, making its shape more oval than round, which complicates the measurement process. Additionally, when tracing the contour of the ring, the thickness of the pencil lead can impact the measurement’s accuracy. Finally, it is essential to ensure the ruler is properly placed and to take the diameter accurately, without underestimating or overestimating it, as every millimeter counts in this exercise.

Ring sizer

On the internet, it’s equally simple to find printable ring sizers. They consist of a series of circles with different diameters, each displaying the corresponding size. The idea is to place one of your rings on the circle whose perimeter matches the inner contour of your ring.

However, besides the issues related to personal judgment in determining which circle closely matches the contour of your ring, one must also consider potential problems related to the material itself.

It’s crucial to ensure that the printable ring sizer includes a scale, such as the one illustrated, as it’s the only way to verify if your print is the correct size. Indeed, between visual perception and the precision of the material, there are numerous possibilities for errors that can quickly accumulate.


In conclusion, it is imperative to recognize that to avoid disappointments and unexpected costs, it is preferable to use a reliable ring sizer, whether at a jeweler’s or when acquiring your own measuring tool. Although supermarket jewelry departments often have ring sizers available, take advantage of your shopping trips to verify your size.

This recommendation is valid not only to ensure the quality of your purchase and manage your expenses but also in the interest of your artisan. Unlike mass-produced items, artisan jewelers do not have a large stock of identical rings in all sizes. This means they cannot simply make a standard exchange and put the other ring back on sale, avoiding any loss. Indeed, each piece is made to measure, according to your specifications. They will strive to satisfy you as best they can, and even if they charge additional fees for any modifications, they will always be at a disadvantage. If any issues arise, don’t hesitate to communicate with your artisan, who will always be attentive to finding a suitable solution.
