First, gather your tools: a flexible, non-stretchable measuring tape is ideal, but a piece of string or a strip of paper with a ruler works just as well. You'll also need a marker to mark your measurement.

Measure the circumference of your finger with a tape measure, piece of string or paper.

Once you have measured the circumference around your finger in millimeters, simply divide that number by 3.14  to calculate your exact ring diameter and match it to our chart!

Timing is key, your fingers naturally swell and shrink throughout the day due to temperature, humidity, and physical activity. For the most accurate fit, measure your finger at the end of the day when it is typically at its largest.
