Ring Size Chart with International Conversion
UK US and EU ring sizes with international ring size conversion chart
Refer to our international ring size conversion chart in the lower section of this page for an accurate conversion from UK to US or EU ring sizes. We have included the internal diameter in mm. for most ring sizes. Our ring size converter works for both wedding rings and engagement rings.
You might look upon the size-stick photograph below as a strange thing for us to include, but this gives you clear photographic evidence of differences between UK and US ring size. Rings are dropped onto the size-stick and size is read along the leading edge where the ring rests.

UK ring sizes to US sizes
Owing to our website showing UK finger sizes, please feel free to look at the size stick which shows UK equivalents to US sizes. We have included this due to the variation of opinion between many conversion charts. If there is no clear equivalent size – contact us – we will be happy to work to the US finger size when we create your ring.

Please keep in mind that some ring designs cannot be re-sized for a variety of reasons. Full eternity rings are the most obvious example of rings that cannot be adjusted by size. Engagement rings with tension style settings are unsuitable for significant size alterations. Claw settings are the most popular style purchased with any uncertainty about finger size. Following size adjustments, claws or prongs can be re-tensioned around the diamond to ensure security for the stone. If you are uncertain about finger size, please feel free to contact us at any time for additional guidance.

Ring Size Charts
The ring size chart below gives some guidance on conversion. Please remember that we can work to in-between finger sizes. Our website allows a full or half size to be chosen. By contacting us before or after placing your order, we can apply further increments. For example you might need size L and a quarter (quarter of a size larger than L) In this instance a size L and a quarter is equivalent to a US size 6. This is no problem to apply if you contact us before or after placing your order.
