Ring Size Guide

This guide is designed to help you find the perfect size for your ring. You can use one of the methods described to get an accurate measurement. The goal is to make the process simple, reliable, and convenient.

📌 Advice

  • Always choose the size taking into account the finger on which you will wear the ring (usually the largest one).
  • Better a ring that is slightly looser than too tight: it must be easy to put on and take off.
  • Finger size can vary throughout the day and with temperature. Measure it at different times of the day for a more accurate estimate.

 

⚠️ Attention:

For wide rings (Belt, Icon, Module, Rail, Xilo, Zip lines, etc.) add one or more sizes .

We suggest you consult the recommended size chart below.

Find your size

We've collected four different, practical and accessible methods to help you determine your correct ring size. Choose your preferred method and follow the step-by-step instructions. The result? An accurate measurement, perfect for you!

Method 1
Use a ring and the Measurement Chart

Download and print the Measurement Sheet . Download here

Preparing the print

  • Set the scale to 1:1 on A4 paper

Checking the print scale

  • Place a credit card in the rectangular area indicated
  • Measure the reference bar, the length must be exactly 5 cm (2 inches)

If the measurements are correct, the print is correct.

Measurement

  • Place the ring on the black circles
  • Identify the circle that fills the interior
  • The number below is your size
  • Choose the next size up for a comfortable fit
💡 Example:

  • The circle that fills the inside of the ring is size 52
  • Choose the next size up for a comfortable fit = size 53
Method 2
Use the Measurement Tool

Download and print the Measurement Tool . Download here

Preparing the print

  • Set the scale to 1:1 on A4 paper

Checking the print scale

  • Place a credit card in the rectangular area indicated
  • Measure the reference bar, the length must be exactly 5 cm (2 inches)

Method 3
Find the inner diameter of the ring

Use an existing ring as a reference to find your size.

Ring Diameter

Measurement

  • Place the ring on a ruler
  • Measure the inside diameter
  • Consult the Measurement Table (Diameter column) to find your size (Size column)
  • Choose the next size up for a comfortable fit
💡 Example:

  • Choose the next size up for a comfortable fit = size 58
Method 4
Circumference measurement

Measure the length that wraps around your finger with a strip of paper or a soft tape measure.

  • Make a mark with the pencil at the overlap point
  • Measure the length with a ruler
  • Consult the Measurement Table (Circumference column) to find your size (Measurement column)
  • Choose the next size up for a comfortable fit
💡 Example:

  • Length measured 52 mm / 2.05 in = size 52
  • Choose the next size up for a comfortable fit = size 53

 

Measurement Table

The Size Chart guides you in choosing the correct size for your ring, starting from the circumference of your finger or the internal diameter of the ring.

The Conversion Table helps you find your correct ring size by comparing international standards: Italy (IT), Europe (EU), United Kingdom (UK) and America (US).
