Ring Size Guide

Find Your Perfect Fit
(Choosing the right size ensures your ring feels as beautiful as it looks. Follow our guide to measure your ring size accurately.)

1. How to Measure Your Ring Size

Option 1: Use an Existing Ring

• Step 1: Select a ring that fits the desired finger perfectly.
• Step 2: Measure the inner diameter of the ring using a ruler (in millimeters).
• Step 3: Match your measurement with the size chart on the right to determine your ring size.

Option 2: Measure Your Finger

• Step 1: Take a strip of paper or a piece of string and wrap it around the base of your finger.
• Step 2: Mark the point where the paper or string overlaps to form a complete circle.
• Step 3: Measure the length of the paper or string (in millimeters) with a ruler.
• Step 4: Refer to the size chart on the right to find the perfect fit for your finger.

Important Tips

• Measure at the Right Time: Fingers can expand slightly at the end of the day or in warm weather. Measure when your hands are at room temperature for the most accurate results.
• Consider Knuckle Size: If your knuckle is larger, choose a size that slides over it comfortably but fits snugly at the base.
• Dominant Hand: Your dominant hand is often slightly larger. Make sure to measure the correct hand and finger.
