How to Use the Canadian Ring Size Converter
Our Canadian ring size converter allows you to easily convert between CA sizes and different sizing systems used around the world. Whether you know your size in CA, US, UK, EU, or any other system, you can quickly find the equivalent in another system.
Four Ways to Convert:
- By Size: If you already know your ring size in one system, select that system and size, then choose which system you want to convert to.
- By Diameter: If you've measured the inner diameter of a ring, enter the measurement (in mm or inches) and select the system you want to convert to.
- By Circumference: If you've measured your finger circumference with string or paper, enter the measurement (in mm or inches) and select the system you want to convert to.
- Visual Comparison: Use our visual comparison tool to compare ring sizes on your screen. Calibrate with a credit card for accurate physical sizing, then place your existing ring on the screen to find the matching size.
For the most accurate results, we recommend measuring your finger at the end of the day when your fingers are at their largest. If you're between sizes, it's usually better to choose the larger size.
