1. Ring Sizes - a summary 

MySilver.co.uk recommends that the best way to establish your ring size is go to a normal high street jewellers and ask them to measure your finger with a special gauge. Indeed we are so confident that when you go into a jewellers and see the prices and styles on offer, then you will want to come back to us!

However, as going to the high street might be inconvenient, then we would like to offer you a way of estimating your ring size by using the following instructions.

2. Estimating the Ring Size

It is important to measure your finger size when you are at your normal size and weight, and temperature conditions are average. Ie, do not measure your ring size after a hot bath or on a very frosty day when your hands are cold.

To estimate your ring size :-

1. wrap a piece of string or strip of paper around your finger so that it is an accurate representation of the ring size you need. Mark where the two ends meet to form a complete circle - making sure that you mark it accurately  - we recommend you use a piece of string which does not stretch and is cut to the ring size you want.

2. take this piece of string or strip of paper and lay if out on a flat surface so that you can measure the length of the material from step 1. Make sure you measure to the nearest millimetre (mm). This is the circumference of the ring.

3. Finally, use the table below to convert the length in mm into a UK ring size.

(note - for piece of mind we recommend that you reverse steps 3 to 1 to check your measurements. To do this take a new piece of material, cut it to the length that represents your ring size in our table and try this on the finger to check if it fits as required).
