Ring Size Guide

How to Measure Your Ring Size at Home

1. Find a thin piece of string, dental floss, or a strip of paper — no more than 1.4 cm (½ inch) wide.

2. Wrap it snugly around the base of the finger you’ll be wearing the ring on.

3. Mark where it overlaps to create a full loop.

4. Lay it flat and measure the length from the start to the mark using a ruler in millimetres.

5. Match your measurement to our ring size chart below for your ideal size.

Pro Tips 

• Measure in the evening, when your fingers are slightly fuller.

• Avoid measuring when you're cold — fingers can shrink by half a size, leading to a ring that’s too tight.

• Wider band? Choose a half-size bigger for comfort.

• Measuring for a surprise gift? Measure a ring they already wear, ask a trusted friend, or borrow a moment when they're not looking to get an accurate estimate.
