Whether you're ordering from Paris or from the other side of the world, here's how to measure your ring size at home, in a few minutes, with no special equipment.
Take a ring that already fits well, on the relevant finger. Measure its inner diameter with a ruler, in millimetres, through the centre. Match this number to the table below to find your size.
Wrap a thin strip of paper or string around your finger, mark where it overlaps, then measure that length with a ruler. Take this measurement at the end of the day, when fingers are slightly more swollen, that's when they're at their most representative size.
