Jewellery Sizing – Ruth Tomlinson

Jewellery Sizing

Please try to provide us with the correct ring size when you place your order. Any of our rings can be resized when purchased through our website except for eternity bands. Your local jeweller can provide you with an accurate size by measuring your finger or another ring of the correct size. Alternatively, please have a look at our ‘ring sizing guide’ for a DIY way to measure ring size - please note that this does not guarantee a completely accurate measurement. If you live in the UK, you can also email us with your UK postal address to request a plastic ring gauge that we can send to you for a more dependable result. If you do provide us with the wrong size then we will happily resize the ring for you once free of charge. If it needs a second resize, this will be a chargeable service and will be quoted for based on the complexity of the resize, plus shipping. 

You can also refer to the table below to establish your ring size based on the inside circumference of each ring size. Please note that this is a guide only and that having your finger precisely measured by a professional with the correct tools is the most accurate way to find out your ring size. Please note that ring size conversions are accurate to within approximately 1/4 of a finger size.

Tips for Measuring your Ring Size

— Your finger size can change during the day – 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 than usual!
— A wider band will feel tighter than a narrower band. When purchasing a particularly wide band, we recommend choosing a full size larger than your normal ring size.
— Your ring should fit your finger comfortably: it should be snug enough not to fall off, but loose enough to slide over your knuckle.
— If you’re buying a gift, the best way to establish ring size is to borrow a ring of his/hers (from the correct finger) and use our ring measuring guide to determine its size.


Your Bangle Size

Bangles are sized by their diameter, rather than by their circumference like rings. We offer 3 sizes of bangle: small, medium and large. In order to establish which is the correct size for you, we suggest measuring your hand, which, if done carefully, will give you an accurate result:

— Place your fist on a flat surface.
— With a soft measuring tape, measure the width from the middle of the first knuckle to the middle of the fourth knuckle (you may need someone to help you with this).
— Compare your measurement to those in the table below in order to establish your bangle size.

Small 62
Medium 67
Large 72


Tips for Measuring your Bangle Size

— Your hands could be different sizes, so make sure to measure the hand on which you intend to wear the bangle.
— Make sure to pull the measuring tape tight over your knuckles. Otherwise your measurement may not be accurate.
