How do I find out my partner’s ring size without them knowing?Updated 2 months ago

The best way to find out a ring size without letting out the secret is to measure an existing ring. We recommend trying to select an existing ring that fits the ring finger - it’s important to note which hand and finger the ring is worn on, as every finger will be a different size.

It will be most accurate to visit a local jeweller and have the ring measured on a jewellers mandrel.

Alternatively, you can measure the internal diameter of the ring (in mm). Ensure this is as accurate as possible as even 1mm can make a significant difference in the final ring size. We recommend measuring with a calliper over a ruler.

If you do not have access to callipers, then you can use our Printable Ring Size Guide here.
