Understanding ring sizes

Whether you're purchasing an engagement ring, wedding band, or a special gift, knowing the recipient's ring size ensures a comfortable fit. But how do you determine the correct ring size? Let's delve into the intricacies of ring sizing to help you make an informed decision.

Traditional ring sizing methods

Ring sizers

Ring sizers, also known as ring mandrels, are cylindrical tools used by jewellers to measure ring sizes accurately. These sizers come in various sizes and are calibrated to match standard ring sizes.

Paper strip method

Another common method involves using a strip of paper to measure the circumference of the finger. Simply wrap the paper around the base of the finger and mark where it overlaps. Then, measure the length of the strip and compare it to a sizing chart to find the corresponding ring size.

International ring size conversion

Ring sizes can vary significantly between countries, making international conversion tables essential for cross-border purchases. Here's a breakdown of some common sizing systems:

UK, Australia and New Zealand

Ring sizes are represented by letters of the alphabet, with half sizes denoted by a combination of letters and numbers.

US and Canada

Ring sizes are typically expressed as a number ranging from 3 to 13, with half sizes available for a more precise fit.

Europe and Asia

European and Asian countries use a numerical scale that corresponds to the inner circumference of the ring in millimetre.

To discreetly find out a ring size, you can employ several subtle methods. 

Borrow a ring

"Borrow" one of her rings that she wears on the ring finger and bring it to us for sizing. Ensure she won't notice it's missing or that you've borrowed it.

Trace the inside

If you can get your hands on a ring, trace the inside of the ring onto a piece of paper and we can use that to size correctly.

Ask family and friends

Enlist the help of close friends or family members who might know the ring size or be able to discreetly find out for you.

Casual conversation

Bring up a friend's engagement or ring shopping and casually ask about ring sizes or styles.
