How to Find Your Ring Size

It can be difficult to determine which ring size you need, especially when that ring is meant to be a surprise. If the rings is for yourself though, there’s a quick and easy way to measure your ring size:

How to Measure Your Ring Size

  1. Cut a thin strip of paper
  2. Wrap the paper around your finger. Make sure the paper is below the joint of your finger and close to your knuckle.
  3. Mark the spot where the paper meets
  4. Unroll the paper and measure the distance between the end of the paper and your mark with your ruler.
  5. Use the following chart to determine your ring size. Rings also come in half sizes, the measurements of which, of course, will fall somewhere in between the whole sizes.

If you’re unsure how to get hold of the ring size then we suggest leaving the ring as our average ring size ‘M’. This will be set as default for all of our rings and the vast majority can be re-sized at a later date; please do check with us before to ensure this can be done.

Other ways to check

If your purchase is not a surprise then there are a few ways you can figure out the correct ring size.

  • The method we have used for many years to get the correct ring size is by asking a close friend of family member of the person who the ring is for to get them to go ring shopping or try on their rings on. (Without them catching on) If they can do this then it’s a great way of figuring out the ring size without suspicion.
  • Visit Your Local Jewellers – Most jewellers work from the same scale in the U.K, visit the jeweller and ask them to take the required finger size.
