A Guide to Necklace Lengths for Men, Women, and Children

If you are particular with how you look with jewelry, then you have to know that there are several considerations before buying a necklace – and one of them is the necklace length.

It is not as simple as choosing a design you like, but you have to take into account the length of the necklace that best flatters your image. Whether you wear a short or long necklace length, it makes a huge impact on your overall look.

Are you looking for a necklace for a date night or a casual affair? Or are you confused about how to style a necklace on t-shirts, dresses, or sweaters?

It can be a bit challenging since necklaces have a variety of lengths that are suited for a specific style and occasion.

Not to worry! I made a detailed guide of necklace lengths for all – men, women, and children. This guide teaches you how to measure a necklace length, how to style them, and factors to consider.

Take a look at your necklace options below before buying one from a store.

How to Measure Necklace Length

Necklaces are usually measured in inches or centimeters. If you already have a necklace you like, measure it with any measuring tool such as a ruler or tape measure.

Once you know the measurement, you can readily buy a necklace of the same length.

However, if you are still figuring out the best necklace length for you, the easiest way to know is by using a clothing measuring tape and wrapping it around the neck.

It is recommended to measure the length in front of a mirror to get a better picture of which length suits you. If you do not have a clothing measuring tape, use any string such as a ribbon or rope that can be tied around your neck.

After securing the preferred length, get a ruler and measure the length or simply bring the string with you to the store to serve as a guide.

If you have a specific outfit you want to pair with a necklace, it is best to measure the length while wearing it to see if the necklace is too short or long for that outfit.

Mens Necklace Lengths Guide

Best Chain Length for a Man

Necklaces are not one-size-fits-all jewelry since each length is designed for a specific height, body build, and shape.

Generally, the average necklace length for a man is 20 inches or 50 centimeters. The length is commonly at the collar bone area just below the base of the neck.

A 20-inch necklace offers a relaxed fit that can be worn inside or outside the shirt. For those with a bigger body build, a 22-inch necklace is typically worn since 14 to 20 inches are already quite tight for the neck.

24-inch and 30-inch necklaces are longer than the average length and are best displayed outside the shirt.

If wearing a pendant, it is suitable with a 22-inch to 25-inch necklace for the most comfort. The longest length is 30 inches which is commonly used only as a chain without a pendant.

The bottom line, the best necklace length should provide enough room to breathe, move comfortably, and represent the style you want.

Factors to Consider to Know the Best Type of Necklace

Know Your Face Shape

A necklace can help enhance the shape of your face as long as you use the right length. For instance, round or oval faces should use longer necklaces such as a 20 to 24-inch necklace to help elongate them. Oval-shaped faces are suitable for most types of necklaces.

For heart-shaped faces, use a 16 to 18-inch necklace to soften the face’s curves. If you want to make your face rounder or neck longer, wear the shortest necklace length such as a choker.

Match With Your Height

The right necklace length can either make you look taller or shorter. If your height is shorter than the average, choose a necklace length between 16 and 20 inches since longer necklaces will only make you look even shorter.

Moreover, long necklaces make it too bulky and look heavy for shorter heights.

For those with an average height that is 5’4” and above, all necklace lengths are usually suitable. However, the most commonly used length for these heights is between 22 to 28 inches.

If you are a very tall person, you can use any length but it is recommended to start with 25 inches.

Accentuate Your Figure

Bodies come in all shapes and sizes, so expect not all necklaces are made for all body builds. For instance, if you have broader shoulders, then smaller necklaces won’t be a good fit.

If you have an hourglass body shape, use a necklace that falls on your chest or cleavage to help emphasize the body’s angles.

For pear-shaped bodies, it is ideal to wear an 18 to 24-inch necklace to make the shoulders look wider. Choker necklaces flatter your figure if you have a long neck.

On the other hand, if you have a shorter neck size, it is best not to use a choker since it makes you look small.

Consider Your Clothing Style

The last thing to consider is the clothes you plan to wear. Not all necklaces match every clothing style and its neckline.

For instance, crew neck t-shirts are best worn with an 18″ inch necklace or any necklace length that falls above the neckline.

If you are wearing a shirt with a low v-neck or halter neck neckline, a 20-inch necklace works well. Dresses or shirts with a boat neck or turtleneck neckline are best paired with longer necklaces with a length of 22 inches.

If you want something shorter than 22 inches, wear a 20-inch necklace for plunging or low v-neck necklines.

Shorter necklaces such as chokers and collars look better on boat necks, strapless, scoop necks, and cowl necklines. For versatility, choose an 18-inch necklace, an all-around necklace you can wear on any clothing style.
