Ring Sizing Guide

We use the European ring sizing unit of numbers, which denotes the circumference of the ring in millimetres. The majority of our rings come in sizes 50, 52, 54, 56, and 58, with some going up to 60 and 62. We do also offer a re-sizing service should you require a ring smaller or larger than our standard sizes - to enquire further, please give our friendly customer service team a call on 0208 912 5510, or email customerservices@azendi.com.

Once equipped with the ring sizer, the ideal time to measure your fingers is at the end of the day when your hands are at their largest. Also be aware that if your hands are cold they tend to shrink by up to half a size.

Slide the ring sizer over the knuckle until it is at the base of your finger, and tighten. You want a comfortable fit - not so loose that it could slip off the finger, but not so tight that you are unable to remove it. There should be a small gap between your finger and the sizer, and you should be able to get it over the knuckle with some ease. Once you have found your most comfortable size, read it from the measurer - if you are on an odd number (say, 53), we recommend you go up to the next even number (in this case you would be size 54).

The final thing to consider is the width of the band that you are looking to purchase. A particularly wide band will feel tighter than a thin band, so you may wish to buy a size up than your normal ring size in a wide ring.


Finally, if you are still unsure, our no-quibbles returns policy means that you can order two sizes to try on at home, and decide which you prefer best! And if you want to talk it through, our Customer Service team are very experienced when it comes to ring sizing. They can discuss all your options with you, including re-sizing rings to ensure the most perfect fit possible.
