Ring Sizes, International Comparisons

Ring sizes, international comparisons can be hard to find. Here is a quick guide.

Get your fingers properly measured

There is really no substitute for getting your fingers properly measured with a ring gauge by a jeweller. Because that way you can be absolutely certain what your size is. You can measure round your finger with a piece of thread and then measure the length with a ruler but it really isn't very accurate and rings need to fit well or they are just annoying to wear!

This can be a very confusing area, especially if you are buying from outside the UK. A brief guide to the most common ring sizes is given below. If you want to check out another size please mail me.
