Size Guide

     Rings

At Leonor Paris, we use European ring sizing (EU).

Finding your size can be done in two simple ways:

  1. The Hands-on Method

Take a soft measuring tape, a string, or a thin strip of paper.
Wrap it around the finger where you intend to wear your ring, mark where it meets, and measure the length (in millimeters).
The number you obtain corresponds to your EU ring size.
For instance, if the circumference measures 52 mm, your ring size is 52.

Please note that your knuckle may be slightly wider than the base of your finger — consider both when choosing your size for comfort.

  2. Measure an Existing Ring

Select a ring that already fits comfortably.
Measure the inner diameter in millimeters and refer to our Size Chart below to find the corresponding EU size.

If in doubt, we recommend contacting our team for assistance. Our experts will be happy to guide you to your ideal fit.

You can also refer to the size chart below for comparison and guidance.

     Bracelets

At Leonor Paris, bracelet sizes correspond directly to their total length in centimeters.
For example, a size 17 bracelet measures exactly 17 cm from end to end.

To find your ideal fit, measure your wrist snugly and add approximately +1 cm for a comfortable fit.

Tennis bracelets: adding 1 cm generally creates the perfect elegant drape.
Rigid bangles: ensure they pass comfortably over your knuckle.
