How to find the correct finger size before buying an engagement ring

How do you find out her ring size before buying an engagement ring? This dilemma affects thousands of engagement ring buyers each year. Here, we have provided a few helpful tips to find out her finger size.

Which finger does the engagement ring fit on?

First of all, make sure you understand which finger the ring goes on. We cover this topic in one of our other posts, worth reading before attempting to discover her ring size.

Measure her ring size whilst sleeping

Is your partner a deep sleeper? She will need to be, for this technique to work. Use A Multisizer strap tool, choosing a moment of deep sleep. Tie the sizer around the third finger of the left hand. You will need some lighting to read the sizing tool and a steady hand so that you don’t wake her.

Find out her ring size from a ring she already wears

Find a ring she already wears. Check if she wears the ring on her other (dominant) hand. This might be larger than her engagement finger. The same finger of the dominant hand can be one to two sizes larger.

Don’t take just any ring. This mistake often leads to incorrect size. Ensure the ring fits her and on which finger it is worn.

Put the ring onto one of your own fingers and mark where the ring stops. Use our free sizer around this line to estimate the size. Alternatively, send the ring to us, or visit a local jeweller to check the size on a mandrill.

Buy a Dummy Ring

Buy a ruse ring—a gift for a relative or friend. Select an inexpensive fashion ring for a relative or friend. Your partner will almost certainly try the ring on out of curiosity. Pay special attention to how this ring fits. This might just give you a good idea of where to aim in terms of ring size.

Get help on her ring size from a relative or friend

Seek the help and guidance of your partner’s friend or relative. They may assist you with a few details. Finger size and ring style especially. This might give you important peace of mind when choosing both the ring size and ring style. In addition, choices including which precious metal may be easier with the assistance of a friend.

Don’t consider if: you have any suspicion they cannot keep a secret. This requires total trust and total secrecy in your confidant.

Estimate finger size from her build

This technique requires some expert guidance. Feel welcome to talk to us and seek further advice. Depending on a person’s build, it may be possible to estimate finger size very roughly. If she has a petite build, her ring size could be between H (small) to J in size. Many girls with a slim to average build average out with a finger size of L. Larger hands typically require sizes above  O in size. If you get close, an adjustment can usually be made to the ring after the proposal. We provide a free size adjustment for size differences of 1 – 1.5 sizes up or down.

Loan a replica engagement ring

Consider borrowing a stand-in replica ring for the proposal. Many men choose this method, going on to choose the final ring with their partner. We hold most of our designs as a showroom (replica) sample rings, available on temporary loan. We have information on our engagement ring pages about how to organise a sample ring.

Be cautious of very big or very small sizes

Be aware of extreme sizes. These may indicate you are incorrect in your size assessment. When using finger size tables or charts to convert diameter or circumferences of rings into a physical size, unless your partner has particularly small or large hands, be aware that size G or size Z respectively may indicate the size you have may be incorrect.
