Planning a surprise proposal? One of the biggest challenges is choosing the right ring size without revealing the secret! Here’s a guide to help you confidently find your partner’s ring size.

A well-fitted ring should slide on easily, sit comfortably, and have slight resistance when removed over the knuckle—this way, it’s snug enough to stay secure without feeling tight. Though having your partner professionally sized is ideal, there are a few discreet ways to make an educated guess if that’s not possible.

Our ring sizer kit, which includes easy-to-use tools and instructions, is the most accurate option if you’re measuring from home. To request one of our kits, simply reach out to us by email. Remember that the dominant hand is usually slightly larger, so make sure you’re measuring their left ring finger!

While not as precise, this can give you a rough estimate. Slide one of your partner’s rings onto your finger and mark where it sits. When you come in for a consultation, our expert team can use this as a reference to estimate their ring size.

If you can borrow a ring your partner wears on their left hand, bring it to our studio or a local jeweller for sizing. You can also take a clear photo of the ring beside a ruler and measure the internal diameter for a more accurate reference. Book your complimentary consultation here.

Casually ask their ring size while pretending to shop for a friend or relative—just a quick, casual question that they’re likely to answer without suspecting a thing!

Rings can feel tighter or looser depending on daily temperature, activity, and even hormonal changes, so we recommend trying it out for a week before resizing. If, after a week, you feel an adjustment is needed, we offer a complimentary resize within the first six months, covering adjustments up to four sizes up or down. Simply schedule a drop-off if you’re based in Melbourne or contact us for guidance on sending the ring in.
