Two simple tricks to determine your own ring size

Everyone knows their own dress and shoe size – but what about the ring size? In fact, it is not difficult to find out without the help of a jeweler. Tikbow knows two tricks with which you can easily determine your ring size yourself.

Measure ring size with paper or string

The ring size can be easily determined with paper, scissors and a ruler. To do this, first place a strip of paper (5 mm wide is ideal) around the finger, which should be comfortable to slip over the joint. Then mark the place where the paper encloses the finger and cut it off at this point. Place the cut strip lengthwise on a ruler, read off the number and you have your size.

Example: 5.8 cm (58 mm) corresponds to ring size 58. If you measure exactly five centimeters with the paper strip, you will have ring size 50. The procedure works just as well with a string, but this is often very narrow and can therefore falsify the result. The finger root where the ring sits is usually thicker than the joint, so the paper method gives a more reliable result.

Determine ring size with existing ring

The simplest method to determine its size is to take an already fitting ring as a basis. The following formula applies: Place the ring on the ruler, multiplying the value of the diameter by 3.14. The result is the ring circumference, i.e. the ring size. Example: If the ring has an inner diameter of 16 mm, 16 is multiplied by 3.14. This results in an inner circumference of 50.24 mm, which, when rounded off, corresponds to a size of 50.

Tips for optimal ring size measurement

During the day, at higher temperatures or during pregnancy, fingers often swell and increase in circumference accordingly. Therefore, it is better to determine the ring size in the evening and/or on warmer days. It should also be borne in mind that the thickness of the fingers on the left hand can differ significantly from those on the right. And: Ring size changes with age, so a regular check will help prevent errors.
