Oscar & Olivia Ring Sizer Guide Free Download

 

Download the PDF file above, print to scale on A4 paper, and using a pair of scissors cut around the dotted lines to reveal your finger sizer. 

You can check the document is printed to scale by measuring the 5cm line once printed. 

Make a slit in the sizer where shown, and wrap the band sizer around your finger, with the end of the band poking through the slit you’ve made.

The sizer should fit comfortably around your finger, take care to ensure that it is not too tight. Make sure you can remove the sizer over your knuckle.

The letter indicated by the “Ring Size” in the slit indicates the ring size you will need. This guide is for indication purposes only, and should you have any questions, please get in touch with us directly and we will be happy to assist you.
