Ring Size Guide
Ring Size Guide
Getting the right ring size is essential for comfort and wearability. Use this guide to measure your ring size at home — no guesswork required.
How to Measure Your Ring Size
Method 1: Use a Ring You Already Own
- Take a ring that fits the intended finger well.
- Place it on a ruler and measure the inside diameter in millimeters.
- Match that measurement to the chart below.
Method 2: Measure Your Finger
- Cut a thin strip of paper (about 1cm wide).
- Wrap it around the base of your finger — not too tight, not too loose.
- Mark where the paper overlaps.
- Measure the length of the strip in millimeters — this is your circumference.
- Match to the chart below.

Tips for Accurate Sizing
- Measure at the end of the day — fingers are slightly larger in the evening.
- Avoid measuring when your hands are cold (fingers shrink in cold temperatures).
- For wide bands (6mm or more), consider sizing up by half a size.
- When between sizes, always size up for comfort.
