Ring sizer

Found a ring you like but have no idea what your ring size is? Don't panic, this tool will help you!

Slide the tool onto your finger, tighten it (without it pinching) and read your ring size through the magnifying glass. This tool measures the circumference of your finger: the most precise measurement, allowing you to convert it to diameter, US size or UK size. Along with the ring sizer, you will also receive a card with a size chart, so you can easily read your ring size in different measurement systems. The measurement system used on this site is the diameter.
