Switzerland, renowned worldwide for precision engineering and luxury craftsmanship, uses the EU/ISO ring sizing system.

Understanding Swiss ring sizing is essential whether you're shopping for jewelry from iconic Swiss brands, visiting jewelry boutiques in Zurich or Geneva, or purchasing directly from Swiss craftspeople.

Beyond its world-famous watchmaking tradition pioneered by brands like Rolex and Patek Philippe, Switzerland has a rich tradition of fine jewelry craftsmanship. Many Swiss jewelry designers blend precision with artistry, creating rings that exemplify both technical excellence and aesthetic beauty. This comprehensive guide explains the Swiss ring sizing system, provides detailed conversion tables, and celebrates Switzerland's contribution to global jewelry culture.

The EU/ISO Ring Sizing System in Switzerland

Switzerland officially adopted the EU/ISO ring sizing system, which measures ring size based on circumference. Ring sizes are expressed as numbers representing the inner circumference of the ring in millimeters. For example, Swiss size 55 corresponds to a ring circumference of 55 millimeters, which equals approximately 17.5 millimeters in inner diameter.

The EU/ISO system is the international standard used throughout Europe and many countries worldwide. This standardization ensures consistency across Switzerland and makes it easy to shop internationally. A ring purchased from a Swiss jeweler with a size 55 will fit identically to a ring purchased from a German, French, or Italian jeweler with the same size 55.

Unlike some sizing systems that use arbitrary numbers, the EU/ISO system's direct relationship to circumference measurements makes it highly practical. You can measure the circumference of your finger and directly compare it to ring sizes. Conversely, if you know your EU size, you immediately know the exact circumference of rings in that size.

The system offers excellent precision. Standard sizes increment by 1mm (size 45, 46, 47, 48, etc.), but many retailers offer half-sizes (45.5, 46.5, etc.), and custom jewelers can create sizes to the nearest 0.5mm for precise fitting.

How to Measure Your Ring Size in Switzerland

1. Using Circumference Measurement

The most direct method is measuring ring circumference. Wrap a flexible measuring tape or soft string around the finger where you want to wear the ring. Mark where the string overlaps, then measure the length in millimeters. This measurement is your Swiss/EU ring size. For example, a circumference of 55mm equals Swiss size 55.

2. Using an Existing Ring

If you have a ring that fits you well, measure its inner circumference with a flexible measuring tape. Wrap the tape around the inside of the ring at its widest point and note the measurement. This circumference measurement is your Swiss ring size.

3. The Ring Sizer App

Download the Ring Sizer app on your iPhone for quick, accurate sizing. The app guides you through measuring on your phone screen and instantly provides conversions to Swiss/EU sizes along with US, UK, and other systems.

4. Professional Fitting in Switzerland

Visit any Swiss jewelry store for professional sizing using proper ring sizers. Swiss jewelers are extremely experienced with accurate fitting and can provide recommendations on size adjustments based on ring width and metal type. This is the most precise method.
