Three ways to measure ring size and convert international ring sizes

A helpful and affordable tool to find your ring size is a Ring Sizer

To tell what size a ring you already have is, simply measure the diameter in millimeters and find the corresponding size in the chart below. Also an easy peasy method for a boyfriend or partner to covertly collect a ring size.

Here's a simple trick to determine your ring size using a few household items:

• Take a piece of dental floss and wrap it around the spot on your finger where you'd like to wear your ring, overlapping the floss. (You can also use string or paper instead of floss.)
• Use scissors to cut the floss off your finger
• Measure the cut piece against a ruler taking the measurement in millimeters
• Find your size from the ring circumference in the chart below.
