[message]The Ring Measuring Tool is a free tool designed to accurately determine your ring size using the universal US number ring sizing system that we use.
Easy to use, simply thread one end of the tool through the gap, tighten it around your finger to your preferred fit, and read the size displayed. This tool takes the guesswork out of finding your ring size, making ring ordering simpler and ensuring a perfect fit every time.

To ensure the best fit, we recommend measuring your finger and comparing the measurements to the circumference and diameter listed in our table. We've included EU, UK, and US sizes for your convenience, making size conversion simple. Please note, however, that our rings are available in US sizes, so you'll need to convert your measurements to a US size when making your selection.
