    How to Choose the Right Ring Size

    We understand that you want to find the perfect fit but ring sizes can seem confusing at first. Here is our guide to ring sizes and finding out your correct ring size.

    What do Ring Sizes Mean?

    The size of a ring can be denoted in many ways and you will often see letters or numbers used to describe the size of a ring. There are three main systems for denoting ring sizes: the Metric Numerical System, the American Numerical System, and the Imperial Letter System.

    We use the Metric Numerical System, which denotes the inside circumference of the ring in millimetres, as it is a very accurate system of sizing. 

    The majority of our rings come in sizes 50, 52, 54, 56, and 58, with some going up to 60 and 62. If you already know your ring size in the American or Imperial system, here is a simple conversion chart for you. 

     Metric Imperial American
    50 J/K 5
    52 L/M 6
    54 N 6.75
    56 O/P 7.25
    58 Q/R 8
    60 S 9
    62 T/U 10

    How Can I Measure My Ring Size?

    If you don't know your size at all then you need to measure your finger. For the most accurate measurement we recommend ordering our professional Ring Sizer.  Your ring sizer will be sent to you by first class post, with a voucher for £2 to redeem against any purchase of an Azendi ring.

    Ring Sizer
    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, so try to measure your fingers when you are comfortably warm.

    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. The thicker the ring, the tighter the fit, so if you choose a ring with a deep band width, you will likely need to go one size up.

    Finally, if you are still at all unsure, our no-quibbles free returns policy means that you can order two sizes to try on at home, and decide which you prefer. You can return the unwanted ring free of charge.

    Other Sizes

    If you check your finger and find that it doesn't measure to one of our standard sizes then don't worry - we do also offer a re-sizing service should you require a ring smaller or larger than our 50 - 62 range.
