Jewelry Size Guide – What You Need to Know

Having the correct size and fit on your jewelry is just as important as having the right size on your clothes. Below, we go through the most common different types of jewelry and size guides for each to help you find the perfect fit.


Most of us have fingers that are a little wider over the knuckle than the rest of the finger. In order for the ring to sit comfortably on your finger and so that you do not risk dropping it, you should choose a size that allows the ring to just cross the knuckle on your finger. This way, it will not sit too tight on the finger, but will still sit securely by means of the knuckle stopping the ring from falling off.

The ring size is usually measured in internal diameter, but can also be measured in circumference. Here you will find a “translation table” from diameter to circumference:

Diameter Circumference Diameter Circumference Diameter Circumference
11,5 36,13 16 50,27 20,5 64,40
12 37,70 16,5 51,84 21 65,97
12,5 39,27 17 53,41 21,5 67,54
13 40,84 17,5 54,98 22 69,12
13,5 42,41 18 56,55 22,5 70,69
14 43,98 18,5 58,12 23 72,26
14,5 45,55 19 59,69 23,5 73,83
15 47,12 19,5 61,26 24 75,40
15,5 48,69 20 62,83 24,5 76,97

There are different ways to measure your size. The easiest way is to measure another ring (which fits) with a slider. If you have no such slider measurment, a ruler will do well.

If you do not have a ring to measure, you can measure your finger with a slider, a tape measure or by wrapping a thread around your finger and then measuring the thread with a ruler.

Be careful with the measurement, as one millimeter corresponds to a full size. Also, keep in mind that the ring must go over the knuckle.

Avoid measuring when your finger is cold, as your finger will swell when it is hot.

Keep in mind that a wide ring usually requires a slightly larger size than a narrow one, as it “sucks” more on the finger and can feel uncomfortable or be difficult to remove if it is too small.

Necklace size guide

There are a variety of lengths on the necklace and it is only you who can judge which length is best for you. Many necklaces are adjustable in size, for example by having several loops on the chain so you can vary the length of the jewelry.

If you want to try out how a certain length fits you, you can measure your existing necklaces to compare lengths, or alternatively take a string of different lengths and try out how it fits you.

Bracelet size guide

The size of the bracelet is normally indicated in perimeter, but for rigid bracelets, it can also be specified in diameter. If you want the bracelet to sit tight, choose a size that corresponds to the circumference of your wrist, but we recommend adding about 0.5-1 cm to make the bracelet feel comfortable around your wrist.

When it comes to Beads bracelets and similar, you should choose a slightly larger size, depending on how many beads you will wear on the bracelet and how large the beads are. Take this into account when choosing the bracelet size.
