Ring Size Guide
Finding your perfect ring size ensures a comfortable fit every time. Here is a step-by-step guide and conversion chart to help you find your exact match.
How to Measure Your Ring Size at Home
Method 1: Measure Your Finger Circumference
-
Cut a strip of paper: Cut a narrow strip of paper (about 1 cm wide) or use a flexible measuring tape.
-
Wrap it around your finger: Wrap the strip firmly around the base of the finger you intend to wear the ring on. Make sure it slides over your knuckle smoothly.
-
Mark the overlap: Mark the point where the paper meets with a pen.
-
Measure the length: Lay the paper flat on a ruler to measure the length in millimeters (mm). This gives your inside circumference (EU Size).
Method 2: Measure an Existing Ring
-
Select a ring that fits the target finger perfectly.
-
Place the ring over a ruler and measure the inside diameter (straight across the inner circle) in millimeters (mm).
-
Match the millimeter measurement with the conversion table below.
Tips for Getting the Right Fit
-
Measure at room temperature: Cold fingers shrink slightly, while warm weather or exercise can cause minor swelling. Measure when your hands are warm.
-
Account for knuckles: If your knuckle is significantly larger than the base of your finger, choose a size in between the two measurements.
-
When in doubt, size up: If your measurement falls between two standard sizes, always order the larger size for comfort.
