Easiest way to measure your ring size at home!
Step 1: tie a string around desired finger
Step 2: wrap the string snug around the knuckle and mark or cut where the string meets to get your fingers circumference.
Step 3: Measure the string up to a ruler on the mm side. Whatever the result is will be the EU sizing conversion i.e. 54mm -size 54.
* If you're more familiar with UK sizing for example (which is in letters) you can see below a ring size chart to check your size in different conversions.
D: (diameter in mm)
C:(circumference in mm)
