How to Determine Her Ring Size and Engagement Ring Style

For any couple, a proposal is a memorable milestone that marks the start of their journey together. It is a singular instance where a question and a ring can shape the course of a lifetime shared.

The presentation of your engagement ring should be as flawless as the love it represents, beginning with a perfect fit and a design that truly reflects a woman's unique style. While the element of surprise is paramount, the discreet and thoughtful effort required to acquire these details is a testament to the depth of your devotion.

This guide is crafted to provide a roadmap for a flawless and memorable proposal, helping you learn how to find out the ring size of your girlfriend and how to choose an engagement ring style with precision.

Part One: The Quest for the Perfect Fit

The journey begins with the pursuit of a perfect fit. Here are a few ways to discreetly gauge or measure her ring size:

Uncover Her Size Through Observation

An excellent starting point is to use your existing knowledge and keen observation. While the average ring size for women (US 6) offers a general reference point, it is crucial to consider individuality.

A woman's ring size can be influenced by her general build and even the time of day, so carefully consider her height and general build when making subtle estimations. While this method is not infallible, it provides a solid foundation from which to work. Remember, the left ring finger is where the engagement ring will ultimately reside, and its size may differ from other fingers.

Below is a general ladies' ring size chart to guide your initial estimations.

US/Canada Size	Diameter (mm)	Circumference (mm)
4	14.86	46.6
5	15.70	49.3
6	16.51	51.9
7	17.35	54.4
8	18.19	57.0

The Art of Indirect Inquiry

For those who wish to go beyond mere observation, finding alternative ways to ask about your partner’s ring size could be an effective approach. It could be as simple as enlisting the assistance of her girlfriends or family members.

How can you get the right-sized engagement ring by enlisting her inner circle? Simply suggest casually steering conversations towards their own wedding plans or jewellery, prompting them to casually gather information on your behalf.

This is also a useful method to find out more about her style and "dream" engagement ring design, which we will touch on in the following section.

Covert Measurement Techniques

For the more adventurous individuals, you can employ a different approach. One of the easiest ways to discreetly measure your partner’s ring size is to carefully measure her finger using a thin piece of string while she is peacefully sleeping. Once measured, you can use a ring sizer or the ring size chart above to determine the size.

For a more precise method, you can create an imprint of a frequently worn ring using high-quality soap or softened wax. This method captures a precise impression of the inner circumference, which a jeweller can use to size your engagement ring.

Alternatively, you can discreetly trace the inner circumference of a ring she regularly wears on her left ring finger onto a piece of paper. This can be done quickly and without raising suspicion, providing you with a valuable reference for your jeweller.

The "Dummy Ring" Manoeuvre (For Confirmation)

Once you've acquired an estimate of your partner’s ring size, an easy way to confirm your findings is the "dummy ring" manoeuvre. You can purchase a stylish, non-precious metal ring and gift it to her as a casual gift, perhaps for a holiday or simply as a token of affection. By casually observing its fit on her specific ring finger, you can confirm your size without raising any suspicion.

Part Two: Decoding Her Style

Once the correct ring size has been secured, here’s what you can do to find the best engagement ring style:

Observing Her Current Jewellery Collection

This is the most personal method for decoding her engagement ring style. Closely observe her rings, necklaces, bracelets, and earrings to identify her preferences. Look for patterns in the metals she wears (e.g., yellow gold, white gold, platinum) and the gemstones she gravitates toward. Also, take note of whether her style is more minimalist and modern or if she prefers a more intricate, vintage-inspired style.

Enlisting Her Inner Circle

As mentioned above, her closest friends and family are invaluable resources in understanding her style. They likely have had conversations about her "dream" engagement ring or have an intimate knowledge of her taste, so discreetly asking them for input on her preferred stone (Diamonds or coloured gemstones), cuts (e.g., round, oval, emerald), and setting styles (e.g., solitaire, pavé, halo) can be helpful in finding the best style.

Uncovering Her Vision

For the bold and direct, uncovering her vision through conversation is the most surefire way to get your engagement ring style right. Gently steering conversations towards her personal jewellery preferences or a recent celebrity engagement ring in a magazine or social media post can prompt her to share her "dream" engagement ring design.

A Masterful Collaboration with Our Atelier

The final and most crucial step is to seek expert guidance. You can arrange for a visit to a reputable jeweller, such as B.P. de Silva, and invite your partner to assist you in choosing a ring under the guise of selecting a different piece of jewellery as a thoughtful gift for a female relative. This could help you subtly gauge her style and preferences.
