For a ring

The choice of the ring size can be a delicate moment when buying on a website, to facilitate this, PREFACE BIJOUX gives you some tips:

  • Measure the widest part of your finger.

  • Preferably, avoid any measurements during the day if your fingers tend to swell.

  • In case of intermediate size, choose the largest size.

Measure using one of your ring:

Make sure that your ring reference is the same finger ring that you want to buy.

Using a millimeter ruler, measure the inside diameter of your ring, and refer to the table below.

You can measure your finger circumference with a tape measure or a twine.

Mark a first line on your starting point, then wrap your measuring tool around your finger and note the closing point.
