Ring Size Guide

Complete International Ring Size Conversion Chart

Finding the right ring size is essential for both comfort and style. Our comprehensive Ring Size Chart makes it easy to convert between different international sizing systems, including US & Canada, UK & Australia, Europe, Japan, Hong Kong, and Switzerland. By measuring either the inside diameter of a ring you already own or the circumference of your finger, you can quickly determine your correct size.

Because finger sizes may fluctuate depending on time of day, temperature, and season, we recommend measuring at the end of the day when your fingers are at their largest. If you find yourself between two sizes, it’s always safer to choose the larger size for a more comfortable fit.

This guide is designed to ensure that your Solvana Jewels ring not only looks stunning but also feels perfect for everyday wear.

How to Measure Your Ring Size

Option 1: Measure an Existing Ring
Use a ring that fits you well. Place it on a ruler and measure the inside diameter in millimeters.

Option 2: Measure Your Finger
Wrap a strip of paper around the base of your finger, mark where it overlaps, then measure in millimeters.

 Fingers can swell throughout the day, so measure in the evening for the most accurate size.
🔹 If you’re in between sizes, we recommend choosing the larger size.
