The Perfect Fit, Made Simple

At MOISI, we believe a ring should feel as good as it looks. Getting the right size is essential to comfort, durability, and everyday wear. That’s why we make the process clear, flexible, and reassuring — so you can order with confidence.

Finding Your Ring Size

All MOISI rings are measured in U.S. sizes. To ensure a flawless fit internationally, we’ve created a global size conversion chart that lets you easily match your local standard.

Ways to Find Your Size:
• Professional Measurement — The most accurate way is to have your finger sized at a local jeweler.
• Measure an Existing Ring — If you already own a ring that fits perfectly, measure its inside diameter
and match it to our chart.
• Use Our Conversion Chart — Easily compare your country’s sizing system to U.S. sizes for a perfect match.

Our Resizing Policy

All MOISI rings are crafted to order and built with durability in mind. While we recommend confirming your size before purchase, we understand adjustments may be needed.


• One-Time Complimentary Resize — Every MOISI ring includes one complimentary resizing within
90 days of delivery.
• How It Works — Contact us, ship your ring back securely, and our artisans will adjust it to the correct size. Once complete, we ship it back to you with insured delivery.
• What’s Possible — Most designs can be resized up or down by one full size. For certain intricate designs (like eternity or heavily detailed pave bands), resizing may not be possible. In those cases, we’ll provide tailored guidance.

Tips for the Perfect Fit

• Measure your finger at room temperature for accuracy.
• Remember that your dominant hand may be slightly larger.
• All MOISI bands are designed with a comfort-fit profile for daily wear.
