Ring Sizing Guide

We use the Metric system on ring sizing, 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. 

To receive a professional ring sizer which you can use at home to measure your finger accurately, please simply order it online here: Ring Sizer
We will send your ring sizer out to you by first class post. The ring sizer costs £2 but comes with a voucher for £2 that may be redeemed against a purchase of any Azendi ring.

If you can't wait, you can download a PDF here which you can print to make your own ring sizer.

If you already know your Imperial ring size, you can use our conversion chart as a guide to our Metric sizes.

How to Measure Your Ring Size

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!

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.
