How to determine ring size

Ring Sizes can vary by brand. Most of the dimensions are expressed in millimetres of the circumference or the inner diameter of the ring (also known as the European ring size). Occasionally the US sizing is being used. But what is the best way to calculate your size?

Ways to determine the size

A convenient way to do it your self is the following: you can take a string or ribbon around your finger and measure the millimetres with a ruler. Just make sure you do not overtighten the ribbon or string, but keep it a little loose. If your number of millimetres doesn’t match exactly the amount of millimetres indicated in the table, then take the closest (larger) size. The best moment to do this is at the end of the day in a warm environment. The reason for this is that your fingers but also your legs will be slightly more swollen. Also when it is colder your hands or fingers “shrink”. So that would mean that maybe you wouldn’t be able to wear your ring in summer.
To determine the inner diameter, you can look up the size in millimetres in the size chart and find the associated inner diameter.

US sizes can also be found in the ring size table by linking the periphery to the designated US size.

Many jewellers or shops where they sell rings can also measure your ring size. The jewellers use special tools to measure ring sizes. You might now them but there is no use to buy something only especially for that.

So this is how to determine your ring size. Simple isn’t it?
