The best way to size your ring is to get your finger sized by a jeweller and most jewellery shops will provide this service free of charge. However if this is not possible, I sell plastic ring sizers on the website. To use this, tighten it to the size you require and make sure you can remove it over your knuckle.
Please be aware that fingers can change in size throughout the day depending on the time of day and the temperature. I would recommend that you check the size a few times in a day to make sure you are ordering the correct size. We cannot guarantee the accuracy of these plastic ring sizers which is why we recommend using a jeweller.
Option 1 - This is the easiest option. Using a bangle you already own and fits you well, measure its internal diameter. Choose or order a bangle that has the same internal diameter.
Option 2 - Place your hand flat on a table. Using a pen mark the middle of the knuckle of your little finger and index finger. Use a tape measure or ruler to measure the distance between these two marks. This distance should be the minimum internal diameter for your bangle. You can go slightly larger than this for a looser fitting bangle.
Wrap a fabric measuring tape around your wrist where you would like the cuff to sit. If you do not have a fabric measuring tape use a piece of string, mark where the string meets the end and then measure this with a ruler.
