Find Your Perfect Fit
At Zoraji, we want every piece to feel as though it was made for you. Use the guide below to find your ring size across the most common international sizing systems.
How to Measure Your Ring Size
The most accurate way to find your size is to measure the internal diameter of a ring that already fits you well, or to measure the circumference of your finger with a soft tape measure or a strip of paper.

Tips
- Fingers tend to be slightly larger in warm weather and at the end of the day — measure at these times for the most accurate fit.
- If you are between sizes, we recommend sizing up.
- For wide band rings, consider going half a size up for comfort.
