Ring Size Guide
Choosing the perfect ring size is essential for comfort and style. Follow our guide below to accurately measure your finger and select your ideal size.
How to Measure Your Ring Size
Method 1: Using an Existing Ring
- Find a ring that fits the finger you want to size.
- Measure the inner diameter of the ring in millimeters (mm).
- Refer to our Ring Sizing Chart to find your corresponding size.
Method 2: Measuring Your Finger
If you don't have an existing ring, follow these steps to measure your finger:
- Wrap a thin strip of paper or a piece of string around your finger, just above the knuckle.
- Mark the point where the paper or string overlaps.
- Measure the length from the starting point to the mark in millimeters — this is your finger's circumference.
- Check the international ring sizing chart to find your size.
Tips for Accurate Measurement
- Measure your finger at the end of the day when it is warm and your fingers are largest.
- If your knuckle is wider than the base of your finger, measure both and choose a size between the two measurements.
- For wide bands (more than 6mm), consider choosing one size larger for comfort.
- Measure multiple times to ensure accuracy.
