Finding the perfect ring size can be a bit tricky, especially as sizes are named differently across the globe. I have made available below an international ring conversion chart to make it easier for you to find your size in UK format. The chart includes United Kingdom sizes from F1/2 - Z+2, along with corresponding sizes in Europe, the United States, and Japan.
If you don't know your ring size in any format, take a look at the Ring Sizing Kit. This product is available to purchase with free delivery included so you can measure your ring sizes from the comfort of your own home.
