Choosing the perfect ring for your partner is a heartfelt gesture, but figuring out their ring size without spoiling the surprise? That’s where things can get tricky!
Whether you’re planning a romantic proposal or celebrating a milestone, getting the right size is a key point but don’t let it stress you out.
With a little creativity and subtlety, uncovering the ring size without them knowing is easier than you might think. To help you master this art, we’ve gathered some simple tips and tricks to guide you on your journey.

1. Borrow a Ring They Already Wear
One of the most reliable and easiest methods is to borrow a ring your partner already wears. Look for a ring they wear on the same finger where you plan to place the new one. Ideally, choose one that fits comfortably, and then have it sized by a local jeweller or by us, whichever is most convenient for you.
2. Enlist the Help of Friends or Family
If borrowing a ring isn’t an option, you can enlist the help of a trusted friend or family member. They may already know your partner’s ring size or could subtly ask them without raising suspicion. This is especially helpful if you need a second opinion or confirmation on the size you think is right. Additionally, they can borrow the ring for you or even try it on themselves to give you a better idea of the size.
3. Use of measuring tape
Another simple method is to use a measuring tape to find your partner’s ring size, ideally while they’re asleep. Gently wrap the tape around the base of their ring finger, ensuring it’s snug but not tight. Take note of where the tape overlaps, and measure the diameter of the finger in millimeters. Once you have the measurement, compare it to our size chart, or reach out to us for assistance to determine the ring size.
4. The Reverse Psychology Trick
If your partner isn’t keen on trying rings or dropping hints, here’s a clever trick: casually mention that you’re thinking of getting a ring made for yourself. Ask them to help you check your finger size, turning it into a lighthearted conversation. From there, you can subtly steer the topic towards their ring size or even sneak a peek at one of their rings to gather clues.
5. The Secret Measurement Trick
You can estimate your partner’s ring size using a ring they already wear, in just a few minutes.
Follow these steps:
- Open your Instagram app
- Go to the camera and take a random image
- Select the paintbrush tool (set it to white) and hold your finger on the screen until it turns fully white
- Once the screen is white, select the brush tool again and choose the 5th option in the top row
- Tap the screen to create a small dot/circle on the white background
- Save the image and reopen it in the Instagram camera
- Place the ring over the screen
- Adjust the saved image so the grey dot aligns with the inner circumference of the ring band
- Once aligned, save the final image
You can then show this image to your local jeweller or the designer you are working with, and they can help guide you on the size further.
Please note: This is only an approximate method. It will help you understand the likely size range, but it is not 100% exact.
When choosing the right size, it’s important to remember that ring sizing can vary slightly depending on the width of the band. This is one of the most crucial factors when designing a ring, as you not only want the perfect fit for your partner but also need to consider the impact on cost. If you’re unsure, it’s often safest to go a little larger, as resizing a ring down is much easier than resizing it up. Consult our sizing guide or simply reach out to us if you need support ensuring the perfect fit.
