Tips for measuring at home
To measure your size at home, use a piece of string or paper tape. Wrap it around your finger, mark the length, and measure with a ruler. Compare the circumference to the chart or measure the inside diameter of a ring you already own.
Differences between EU, US and UK sizes
EU sizes are based on circumference in millimeters, while US uses a numerical scale with fractional values. In the table above, you can easily compare the different systems and choose the most appropriate standard.
