Please try to provide us with the correct ring size when you place an order. 

To obtain your ring size you can go to a jewellery shop to have your finger measured and sized. 

Measuring your finger with string or paper will not produce accurate measurements; order at your own risk if using sizes obtained in this manner. 

Alternatively, you can size your ring at home using the ring multisizer for sale on our website although this will not measure to half sizes so may not be suitable for all fittings. 

Alternatively, you can measure the inner diameter of an existing ring you have. You can then refer to the table shown to determine your ring size based on the inside diameter of each ring size. Please note that this is a guide only and this does not guarantee a completely accurate measurement, Deborah Tseng Jewellery does not accept responsibility for re-sizing for ring measurement carried out in this way. Having your finger precisely measured by a professional with the correct tools is the most accurate way to measure your ring size.



Deborah Tseng Jewellery operates in standard UK ring sizes and refers to the inside ring diameter as the preferred measurement. The suggested US and European sizes in the table below are shown for reference only.


Please note that rings of the same size may have slightly different fits depending on the ring design.


If in doubt or if you cannot find your ring size please contact


  • How should your ring fit? 

Your ring should fit comfortably: it should be tight enough not to fall off, but loose enough to slide comfortably over your knuckle.


  • When should you measure your ring size? 

The best time to measure is at the end of the day when your fingers are at their largest. Do not measure when your hands are cold as your fingers could be up to half a size smaller.


  • How to find out someone else’s ring size?  


If you’re buying a gift, the best way to establish ring size is to borrow a ring of theirs and use the ring measuring guide to determine its size.
