Ring Size Chart - European, American and Other Systems

Ring sizes can be given in different systems depending on the country, so before buying – especially online – it is worth making sure which scale you are dealing with. In Poland, as in many European countries, the system is based on the inner diameter of the ring expressed in millimetres. For example, size 12 means that the ring has a diameter of about 16.6 mm.

How to use the size chart – a practical guide?

A ring size chart may seem complicated at first glance, especially if it contains several systems – European, American, British or Japanese. In practice, it is a very helpful tool that just needs to be read carefully.

First, measure a finger or ring you already have.

  • if you measure the circumference of your finger (e.g. with a paper tape measure), look for this value in the column marked "circumference (mm)";

  • If you are measuring the inside diameter of a ring, find it in the "diameter (mm)" column.

Next to each of these values, you will find its assigned ring size in the European system (i.e. the one used in Poland). This is the number that should interest you when buying - for example, size 12 corresponds to a diameter of approx. 16.6 mm and a circumference of 52 mm.

If you’re buying jewelry abroad, look at the columns with other systems. Find the row with your European size and see what letter, number, or value is assigned to it in that country.

Is your result somewhere between two values? Choose a slightly larger size – especially if the ring has a wide band or if your hands tend to swell.

Best Practices – How to Choose the Perfect Ring Size?

Now that you know what options you have to choose from when trying to measure your ring size, here are some handy tips to make the whole process a lot easier!

Factors influencing finger circumference variability

Have you ever wondered why a ring that fits perfectly in the morning feels a little tighter in the evening? It's no coincidence - the circumference of your finger can change throughout the day, and its size depends on many physiological and environmental factors.

The greatest influence is the ambient temperature - fingers tend to swell on warm days, while they become slimmer in the cold, so it is best to measure your finger in the evening, in neutral conditions, when your hands are rested and warm, but not overheated.

The change in size is also influenced by:

  • hydration of the body,

  • physical exertion,

  • hormone levels (e.g. during the menstrual cycle or pregnancy),

  • long-term immobilization of the hand (e.g. working at a computer),

  • and even a diet high in salt, which retains water in the body.

For greater accuracy, it is worth measuring the finger several times at different times of the day. A well-chosen ring should easily pass through the ankle and fit comfortably on the finger – without pressure, but also without the risk of slipping off during everyday movements.
