Use an existing ring
Measure the inner diameter of a ring that already fits the same finger, then compare the millimeter value with the chart.

Ring Size Guide
Measure carefully before ordering a made-to-order ring. If you are between sizes, buying a wider band, or converting between country size systems, ask before checkout so the order can be prepared correctly.

A ring size should be checked before ordering because each Chantal Vaulet ring is made to order. The safest approach is to compare a known size, an existing ring, or a professional measurement against the conversion chart.
Finger size can change during the day and with temperature. For a high-value or custom ring, confirm uncertainty before purchase rather than guessing.
Measuring
How to measure before ordering
Use paper or string carefully
Wrap it around the finger, mark the overlap, and measure the length. Keep it snug but not tight, and repeat the measurement.
Visit a jeweler
For engagement rings, wider bands, or expensive custom work, a professional measurement is the safest option.
Measure more than once
Hands can swell with heat, cold, salt, travel, and time of day. Compare several measurements before deciding.
Markets
Which size system applies in each market?
USA and Canada
Use US/Canada numeric sizing, then compare against the millimeter diameter if you know the inner measurement.
United Kingdom and Australia
Use UK/Australia alphabetical sizing, then compare against the US and EU columns when ordering internationally.
France, Belgium, Denmark, Germany, Netherlands
EU and mm-based sizing are common. Confirm whether your measurement is inner diameter or circumference before converting.
Details
What to know
Measure at the right time
Finger size can change with temperature, salt, travel, and time of day. Measure more than once when possible.
Consider band width
Wider bands can feel tighter than delicate bands. Ask for guidance if the design is unusually wide or stacked.
Use local systems carefully
US, UK, and EU size systems do not map perfectly in every case. Use the chart as a guide and confirm uncertainty.
Questions
Common questions
What if I am between two sizes?
Ask before checkout. The best answer can depend on the ring width, finger shape, stack plans, and whether the ring will be worn daily.
Should a wider band be ordered larger?
Wider bands can feel tighter than delicate bands. If the design is wide, stacked, or unusually structured, ask for size guidance before ordering.
Can I use the chart for every ring?
Use it as a guide, not a guarantee. Size systems vary slightly and handmade or made-to-order pieces should be confirmed carefully.
