How To: Finding Out Your Partner’s Ring Size For a Surprise Proposal

When ordering an engagement ring, it can be hard to know what ring size to choose - especially when you’re planning for a complete surprise! 

Firstly, let’s talk about the optimal fit of your ring. Ideally, the ring should go on easily, sit comfortably, and have a bit of resistance over the knuckle when being removed. Without this resistance, your ring is at risk of coming off when you don’t want it to.

Whilst we usually recommend being properly sized by a professional, we completely understand that this may not be achievable when keeping things a secret. Below are some of our best tips for making an educated guess;

Our first and most accurate recommendation is our complimentary ring sizing kits. Equipped with all the tools and instructions you need, you can use this ring sizing tool from the comfort of your own home, and purchase your partner's dream ring with confidence. Keep in mind that your dominant hand tends to be slightly bigger, so make sure you are measuring your partner’s left ring finger. Simply request one of our free ring sizers here, or get in touch via email.

Check for sizing stamps inside your partner's rings. Take the time to discreetly search through your partner's jewellery box and look for hallmark stamps on the inside of the ring. Typically you can identify the ring by a letter or number (For example, “52” or “M”). At The Moissanite Company, we work with standard Australian ring sizing. Wherever you are located in the world, refer to our international sizing chart so you convert the measurement and choose the right ring size.

Compare their rings on one of your fingers. Whilst this method is a little less accurate, it will still give a rough indication of your partner's ring size. Simply place their ring securely on your fingers and mark where it sits. If you are coming in for a one-on-one consultation, you can have our expert consultants more accurately estimate the size of your finger at that designated point for a rough estimate on size.

Bring one of their rings into a consultation, or your local jeweller. Find a ring your partner wears often, ideally on their left hand, and take it to a local jeweller or to your consultation to have it professionally sized. Whilst there will be a slight difference in sizing depending on which finger this ring is worn on, it will still give you a great indication. If you are unable to do this discreetly, simply take a photo of their ring next to a ruler. From this, you can measure the widest area inside the ring from inner edge to inner edge - gaining an inside circumference.

Ask them - discreetly! You can pretend you are purchasing a ring for a close relative, sibling, mother, grandma or even yourself. Ask your partner what size they are for reference and make sure to keep note. 

While we have a few recommendations on how to make an educated guess, we know sometimes it’s just not possible to get it perfect. If when you first receive your ring, it mostly fits but you’re concerned it might be a little too loose or a little too tight, we recommend wearing it for at least a week before deciding whether or not to resize it. This is because our fingers can fluctuate in size, due to temperature, weather, hormones and even exercise.
