Ring Size Guide

To help you choose the correct ring size quickly and accurately, we have prepared this ring size guide. You can either compare your usual local size directly or measure your finger circumference in millimeters and match it with the chart below.

Quick Reference (Most Common Men’s Sizes)

US 8–9: Slim fingers
US 9–10: Average men’s size
US 10–11: Wider fingers

If you are unsure about your size, we recommend measuring your finger circumference first and then checking the chart for a more accurate fit.

How to Measure Your Finger

Wrap a thin strip of paper or a piece of string around your finger.
Mark the point where the ends meet.
Measure the length with a ruler in millimeters.
Use the chart below to find your corresponding ring size.

Tip: Measure your finger at room temperature for the most accurate result, as fingers may expand or shrink depending on the weather. If you are between two sizes, it is usually better to choose the larger size for a more comfortable fit.

Please Note

Finger size may vary depending on which finger you plan to wear the ring on, so please measure the exact finger you intend to use.
Wider rings usually fit more tightly than narrow bands. If you are purchasing a wide ring, choosing half a size or one size up may provide a more comfortable fit.
If you are still unsure, please contact our customer service team and we will be happy to assist you.
