Choosing a thumb or midi ring size is easy!

Thumb - Size one up from your pointer finger if you wish to wear on the thumb.

Midi Ring - If you wear a size 5-7 select size 3 3/4. If you wear size 8-9 select size 4. 10-11 size 5.

From our years of experience we find these work 9 times out of 10. If you want to be 100% sure please use the size guide.

Remember, this is a very small measurement. If you measure yourself to be a size 16.5mm and we only have a size 16.25mm in stock, this is just a quarter of a mm (look at a ruler and you will see how small that is) so it's safe to say that a size 16.25mm will still fit comfortably.

Your body temperature matters when sizing and changes throughout the day. Cold skin will contract and warm skin expand, so we recommend sizing a few times throughout the day so you can get a better idea of your true ring size.

Consider sizing up on rings if you are between sizes. A ring that is too small is much more likely to break or get damaged because of the extra pressure being exerted on the band.

You can find products called 'ring snuggies' online to help with any rings that may be slightly too loose. This is a little piece of plastic that can be discreetly wrapped around the back of the band to adjust the fit.
