How To Get Someone's Ring Size Without Them Knowing

An engagement ring is a milestone purchase worn for the rest of your life. With that in mind, you’ll want to choose a ring that is not only beautiful but durable and well-fitting.

Before shopping for the perfect engagement ring, it’s important to know your partner’s ring size, especially if you’ve opted for a surprise proposal. That way, you can be sure the ring will fit comfortably and look great on her finger. Measuring your partner's ring size without her knowing can be tricky, but it's not impossible.

If you're worried about ruining the surprise, rest assured that there are a few ways to accomplish your mission. First you can check out our ring size guide where you can download our ring size chart.  Then if you’re wondering how to get someone's ring size without them knowing, we’ve listed some of the most popular methods:

Borrow a ring from her jewellery box

One of the easiest ways to find your partner’s engagement ring size is to borrow one of her most loved and most worn rings so you can bring it to a jeweller to be sized. It’s important to note which finger and hand your partner wears the ring on. The fingers on her dominant writing hand may be a little larger, so ensure you check which finger she wears the ring on before you begin the process. You also need to check whether the ring you’ve chosen is the right fit, i.e. it doesn’t feel tight or slips off.

Make sure you don’t borrow her favourite piece of jewellery (she may fear she’s lost it) and remember to put the ring back before she notices — you don’t want to ruin the surprise.

Once you have her ring and you’re certain it fits well, you can bring it directly to Artelia’s skilled artisans, who know exactly how to measure ring sizes in Australia.

Trace Out One Of Her Rings On Paper

Worried that you might lose the borrowed ring and need a more accessible tip on how to get someone's ring size without them knowing? A textbook way to covertly uncover her ring size is to simply trace the inside of one of her rings on a piece of paper. Do this several times to ensure the outline is accurate and consistent. Once you have a tracing of the inner circle, simply take it to our Artelia jewellers, and they will be able to give you an accurate measurement that will help you create a bespoke band for your wife-to-be.

Go incognito

There are many sneaky tactics that can help you figure out how to get someone's ring size without them knowing. You can start by asking her about her favourite outfits and slowly work your way into asking her about her jewellery preferences. You can also purchase an inexpensive ring and pretend it’s for your sister or mother, ask her for advice and check the fit on your partner’s finger. Make sure you’re as subtle as possible —  you don’t want to blow your cover and ruin the surprise.

You could also take her on a “pretend” shopping trip for another piece of jewellery. When you’re at the jewellery store, you can inform the salespeople that you’re thinking about getting engaged and ask them to note her ring size as she tries on different types. If you need more tips, you can ask Artelia’s expert team, who are professionals in helping figure out how to measure ring sizes in Australia.

Enlist Help From Friends And Family

Subtly determining your partner’s engagement ring size is essential to ensure your surprise proposal goes off without a hitch. So, why not ask her friends or family if they know her ring size? This tactic is a bit risky as someone could inadvertently let the information slip — so ensure you’re confident they can keep the secret before you confide in them. Asking a friend to take your partner shopping is another great way to get an insider's scoop into your future wife's personal jewellery preferences.

Don’t Forget To Gauge Her Personal Aesthetic

While playing detective to get your partner’s engagement ring size, find out what style she favours, as this will help you pick the diamond cut and band design. Does she tend to wear dainty pieces or statement-making jewels? She may prefer an engagement ring with a minimalist band if she wears delicate jewellery. Alternatively, if she loves opulent and bold designs, she may opt for a sparkling solitaire diamond ring or something with a rich and striking setting. Once you understand the general styles she prefers, you can start narrowing your search.
