How to select a ring size

Selecting the right ring size is not complicated at all. In this text, we suggest several effective methods which should make this task easier.

Before we get down to work, keep in mind a few important issues:

  • The ring can sit differently on the finger depending on the season. In summer fingers are slightly swollen, which increases the size.
  • Often the joints of the fingers have a larger diameter than phalanges, therefore you should select the ring size so that it goes over the widest part of the finger with SLIGHT resistance.
  • The construction of the ring influences how easy it is to put on and take off. If you are buying a ring with a wide band, it is good to choose one half a size larger.


Method 1 - measurement at a jeweller

To find out what size ring you need, you can go to your nearest jeweller and request a measurement. Depending on the case, the size can be established in two ways:

- By measuring the finger using special measuring rings

- By measuring a ring that you bring in which is the right size

This is a quick and reliable method. We recommend having measurements done with two jewellers in order to be sure of the measurement.


Method 2 - Independent measurement of a suitable ring

To find out what size you are, we have to establish the diameter of the ring. Also, remember that items that are worn often have various mechanical faults, so before measuring it is good to check whether the jewellery we will be using has the ideally round shape. The most simple and precise way to measure it is by the internal diameter using a calliper gage. It is best to do this in several places on the ring so the measurement would be reliable. Then please enter the results into Table 1 below.


Method 3 - Measure the ring using a stencil.

We have prepared a special stencil for you which should allow you to measure the ring easily. After printing the file according to the instructions (without margins), compare the ring to the specific circles until you find the one that ideally covers the internal line of the band. Before taking a measurement, check on the special gauge whether it will be possible to print the stencil at the right scale.

Method 4 - Measure finger circumference using string.

If you don't have a suitable ring and, for whatever reason, you're not able to make it to a jeweller, there is a fourth, but less reliable, method of measurement. To do this, you just need a piece of string which you wrap around the widest point of the finger. Then mark the circumference, unwind the string and measure the length with a ruler.

If you already know the circumference of your finger, put the result in Table 1 below and read the measurement.
