Not sure what Ring Size you need?
Firstly, let us say that for added peace of mind, we offer a free complimentary ring resize on all engagement rings purchased with us, helping ensure the final fit feels comfortable and secure after the proposal, even if you didn't quite get the size right!
Of course, planning a surprise proposal can feel exciting, emotional and sometimes slightly overwhelming, especially when it comes to choosing the correct ring size. While the perfect engagement ring style is important, ensuring the ring fits comfortably is equally essential. The good news is that there are several simple and discreet ways to estimate your partner’s ring size without spoiling the surprise.
At Avanti, we understand that getting the exact size right straight away is not always easy, particularly when planning a proposal in secret. Our ring buying guides are designed to simplify every stage of the process, from choosing the perfect engagement ring to understanding sizing, comfort and long-term wear. With a little preparation and the right advice, you can feel far more confident selecting a ring they will love wearing every day.
Ways to Find Your Partner’s Ring Size
Borrow a Ring They Already Wear
One of the easiest ways to estimate ring size is by borrowing a ring your partner already wears regularly. Ideally, choose a ring worn on the ring finger of their left hand, as sizes can vary between fingers and hands. You can then use our ring sizing tool to find out what size it is.
If you are unable to print the tool, trace the inside of the ring on paper or discreetly take it to a jeweller for measurement. Even a close estimate can provide a useful starting point when selecting an engagement ring.
Ask Friends or Family for help
Close friends, siblings or family members may already know your partner’s ring size or could help you find out naturally in conversation. This can be particularly useful if your partner has spoken about engagement rings before or regularly shops for jewellery with someone close to them.
Use a Ring Size Guide at Home
Printable ring size charts and measuring tools can also help if you have access to a ring they already wear. By placing the ring over a sizing guide, you can estimate the closest match. At Avanti, we always recommend measuring as accurately as possible to help minimise future adjustments.
Things to Consider When Choosing Ring Size
Finger Size Changes Naturally
Finger size can fluctuate slightly throughout the day depending on temperature, activity and even hydration levels. Fingers are often slightly larger in warmer weather and smaller during colder temperatures, which is completely normal.
Because of this, a ring should feel secure without being overly tight. A well-fitted ring should slide on comfortably while offering slight resistance when removed.
Wider Bands Fit Differently
Ring width can also affect sizing. Wider engagement rings and wedding bands tend to fit more snugly than slim designs, meaning some people may prefer a slightly larger size for comfort.
At Avanti, our ring buying guides help explain how ring profiles, widths and settings can influence overall fit, helping you choose a ring that feels as good as it looks.
Surprise Proposals Don’t Need Perfect Precision
If you are planning a surprise proposal, remember that getting the exact size immediately is less important than creating a memorable moment. Most rings can be resized after the proposal if needed - and the first resize is free when a ring is purchased at Avanti! - giving you flexibility and reassurance during the buying process.
Final Advice from Avanti
Choosing the right ring size may seem like a small detail, but it plays a big part in how comfortable and enjoyable a ring feels to wear every day. Taking the time to estimate carefully can help make the proposal experience smoother while reducing stress during the buying process.
At Avanti, we believe engagement ring shopping should feel exciting and enjoyable rather than complicated. Our expert buying guides are designed to help you confidently navigate everything from ring sizing and diamond selection to ring styles and precious metals.
