    Measuring the circumference of your finger

    You can measure the circumference of your finger by using a tape (this mustn’t be any wider than 2cm).

    A note on ring thickness – If you’re choosing an especially thick ring, with a significant band width, you’ll probably want to go up by one size for a suitable fit.

    Step 1

    Wrap the tape around your finger. Ensure that this paper ring can then slide easily over your knuckle.

    Step 2

    With a pen, mark the part where the tape overlaps.

    Step 3

    Work out the millimetre measurement between the start of the tape and your mark. You can then use the above table to find your ring size.

    Ring Size FAQs

    “How can I ensure that my ring fits me?”

    We always recommend an in-person visit to ensure that your ring will fit, however, should you order without having a proper sizing only to find that your ring doesn’t fit, our expert artisans can resize it for you.

    “How can I know the ring size for a surprise proposal?”

    The most effective way to discover your partner’s ring size is to get hold of a ring that she wears often on their middle finger. Whilst this is still an imperfect science (and you may need to go up or down a ring size following the proposal), it will stand you in far better stead than simply guessing).

    “I can’t get hold of one of her rings/she doesn’t wear rings – what now?”

    If she does have a ring, but would notice if it went missing, you can use the paper tape instructions listed above to take the inner measurements of the ring. Alternatively, if your partner sleeps incredibly soundly at night, you can try one of the many downloadable ring sizers that can be found online.
