Styles and types of necklace explanation

Let’s take a look at the types mentioned above and their various advantages and disadvantages.


All sizes used to be called a collar. Nowadays, a collar necklace is arond 13 to 15 inches (33 – 38 cm). So this type is typically worn high on the neck. A collar can be made of any material but it is most commonly made with leather or string, as well as other materials such as metal (gold, silver, titanium), plastic and beads. Especially on a longer neck, the collar necklace fits perfectly.

Many people confuse a choker with a Collar. However, it is slightly longer and has a slightly wider fit. A choker is normally between 15 – 17 inches long (38 – 43 cm). It is a very stylish necklace with an open neck. However, a choker worn on a short neck can make it look like the neck is also short. In addition, rounder faces are better off with a longer chain.

The right necklace size length for men and women

The right necklace size is determined by the length of your neck and the type of jewelry you want to wear. In addition, necklace sizes are measured in inches or centimeters, and they vary depending on the type of jewelry you’re looking for. In summary, the average necklace length for men is 20 Inch (50 CM). However, for women is the necklace length 18 Inch (45 CM) on average.

However, longer necklaces are also becoming more and more popular these days.

The Difference in Widths Between Different Types of Jewelry Chains

Other than the length, the width of chains is often calculated in millimeters. This can vary from 1 to 25 mm. Because, less than 1 millimeter thickness is at the expense of strength.

On average, most men choose a chain of 2 to 6 mm. Certainly if it has a pendant, you will quickly opt for a thicker version (4 to 6 mm). Still, women prefer a thinner chain of 1 to 4 mm on average. If you wear a 6mm thick chain, it really is a big statement chain.

Therefore, the thickness is certainly decisive for the appearance of the design. However, few websites have this filter built in unfortunately. So below is an overview of the average thicknesses per type. Also keep in mind that the thicker the chain is, the more expensive it is to purchase.

Other body factors that affect the measurement

The right measurement enhances your style and appearance. That is why it is important to also take the following body factors into account:

  1. Neck size
  2. Face shape
  3. Body type and height

Let’s briefly explain these below, so that you make the best choice.

Neck size

The size of your neck is especially important for short necklaces, such as a collar. Add 5 CM (2 Inch) to your neck size, so that it is comfortable to wear. Would you like to wear a charm or pendant? Then it is better to add at least 10 CM (4 inches).

Face shape

Do you have a round face? Then wear a slightly longer necklace. Otherwise your face will look even rounder. In contrast to a long neck and narrow face. In that case it is interesting to wear a shorter necklace, so that your neck gets extra volume.

Body type and height

In addition to neck and face, your height also has an impact on length. For example, it is better to wear a shorter necklace if you are shorter than average. Long necklaces match well with longer postures. Finally, you can also take your body type into account. The accessory draws attention from the eyes, so make sure to accentuate what you like.
