If you are choosing a ring for your partner that will be a surprise, it's important to begin with a size that is as close as possible to their true ring size.

All of our rings come with a complimentary resize - this doesn't expire and we resize the majority of our rings that are a surprise - but we don't recommend resizing more than 3 sizes as it can change the overall appearance of the ring design.

With this in mind, there are several methods by which you can work this out and we've shared our favourites below.



We've created a ring guide below that you can download and print. Lay your partner's ring on top of the sheet and see which size matches the inside of the ring. 

It's important to ensure that the image is saved as its full size, and is scaled to fit the page when printed at 100%. These instructions are included in the guide. It's also good to bear in mind which finger your partner's ring is worn on - if they don't wear it on their ring finger of either hand then let us know, and we'll be able to help you approximate which size their ring finger would be in relation to the existing ring.

If in doubt, please feel free to email us a picture of the ring and ring sizer, and we will do our best to help you - get in touch at info@rachelboston.co.uk.



If you don't have access to a printer, the inside of your partner's ring can be measured with a ruler. Make sure that you're only measuring the open space inside of the ring, rather than any metal. 

If in doubt, please feel free to email us at info@rachelboston.co.uk.



After 10 years in the jewellery industry, Rachel is well versed in ring sizes and can often approximate it from a photo. Simply gather a few images in which your partner's hands are visible and email them to info@rachelboston.co.uk.
