How to Find Ring Size Without Asking

If you’re wondering, how do I figure out my girlfriend’s ring size without asking?, you’re not alone! The key is to be subtle and resourceful. One of the simplest tricks is to borrow a ring she already wears and use it as a guide.

Just remember, each finger is slightly different in size. Typically there’s a two-to-three size difference between fingers on the same hand. If she wears a ring on her middle finger, count down about two sizes for a closer estimate of her ring finger size.

If you're able to sneak away with one of your partner's rings, you can also bring them to our Manchester and London Marylebone showrooms and we can double check the ring size in person! Alternatively, have them measured by a local jeweller, and report back on the size from there. 

Browse our stunning solitaire and trilogy engagement ring styles once you have an idea of her size, you’ll find timeless designs that make the perfect surprise proposal piece.

How to Measure Ring Size in Secret

If you’re still unsure how to measure ring size in secret, there are a few low-pressure ways to do it. You can order a free ring sizer directly to you, and with a little help from a trusted friend or family member, measure her finger when she’s least likely to notice.

If that’s not possible, try tracing one of her rings on paper or pressing it into a bar of soap to create a quick impression. Both can give a jeweller enough information to make an accurate estimate.

Not sure which style she’ll adore most? Explore our full engagement ring collection, natural diamond engagement ring styles or gemstones engagement rings for an alternative twist. From classic brilliance to colourful elegance, there’s something for every love story.

Ask Friends or Family

When in doubt, ask her loved ones! If you’re trying to figure out how to find the ring size of someone, her close friends or family might already know, or they can casually find out without raising suspicion.

They might even have inside knowledge if she’s mentioned her dream ring, whether it’s a pavé diamond ring, a sapphire engagement ring, or a unique trilogy design.
