Ring Sizers & Conversion Chart

How does the Multisizer work?

The ring sizer gives the UK finger size reading when wrapped around the finger. Find out your ring finger size at home. This system replaces DIY methods of getting your finger measured using a piece of string or a strip of paper. Measure your ring finger size with ease. Similar to a cable tie, one end inserts through a gap and tightens around the finger. Don't worry; the sizer will come off. 

Don't tighten the sizer too much; otherwise, the strap will open and give a false reading. Use this link to email us to order your UK size tool. The tool is reusable and easy, easily recycled or passed to friends and family afterwards. A family member will likely have use for this at some point soon.   

Once you have the perfect ring size, talk to us, and we will help you with the next stage, finding the perfect ring that fits. Our expert team help remain on hand ready to help when choosing a ring for any special occasion.
