rings Yazzy's ring sizes

Ring Sizes can vary by brand and also by country. So you could also ask what ring sizes are there?

We express most of the dimensions in millimetres of the circumference of the inner diameter of the ring (also known as the European ring size). Occasionally the US sizing is used. But what is the best way to calculate your size, and how do ring sizes work?

Ways to determine the size

A convenient way to do it yourself 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 precisely 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. Even 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. This is the way to know the ring size of a ring with a ruler.

To determine the inner diameter, you can look up the size in millimetres in the size chart and find the associated inner diameter. So, for example, if you want to know the ring sizes diameter in centimetres, you just read on your ruler in cm.

With our table, you can easily read your ring size into the different sizes used worldwide. Also, to convert the ring size from the US to EU size can be read in this table. Or to read the ring diameter from mm to inches is no problem.

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 know 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?
