Two ways to measure your ring size accurately — from anywhere in the world. Choose the method that works best for you.
The most accurate method. All you need is a thin strip of paper (or string), a pen, and a ruler. Takes less than 2 minutes.
Enter your finger circumference below and we'll find your size instantly.
⚠ Stylex does not offer size exchanges. Please confirm your size before ordering.
Print this page at 100% scale. The printed document includes step-by-step instructions, all ring size circles, and a full size reference table — everything you need on one sheet.
Use a ring that already fits the finger you plan to wear the new ring on. Place it flat on the circles below.
Align the inner edge of your ring with the circles. The circle that fits just inside the ring — touching the inner edge all around — is your size.
