How to Choose the Right Necklace Size? The Complete Guide

You have found the perfect necklace, but at the moment of placing your order, the question arises: what length should you choose? Too short, and it risks being uncomfortable. Too long, and it will lose its visual impact. Choosing the right necklace length is one of those small decisions that make all the difference between a piece of jewelry you love to wear and one that stays at the bottom of the drawer.

This guide gives you all the keys to choosing the ideal length, whether for yourself or for gifting a personalized necklace to someone you love.

The different necklace lengths: the reference guide

First of all, you should know that necklace lengths are standardized in the world of jewelry. Each length has a name, a position on the body, and a preferred usage.

The choker necklace (35 to 40 cm)

Also called a choker, this necklace is worn very close to the throat, just below the Adam's apple. It is the trendiest length in recent years, particularly highlighted by minimalist jewelry brands. It is particularly suitable for women with a long, slender neck, as it emphasizes the throat and collarbones.

Note: this length may feel tight on a short or wide neck. If you opt for a name necklace in a choker version, check that the chain has an adjustable extension system.

The princess necklace (42 to 45 cm)

This is the most worn length in the world. The princess necklace falls just below the collarbone, at the base of the neckline. It adapts to all body types, all clothing styles, and all occasions, from everyday life to dressed-up outfits.

It is the default length for the vast majority of personalized necklaces, and for good reason: it is universally flattering. If you are unsure which length to choose for a gift, this is the one. You cannot go wrong.

The matinee necklace (50 to 60 cm)

The matinee necklace falls at the sternum or the start of the bust. It is an elegant length that gives movement to the jewelry, ideal for wearing with a round neck or a low-cut outfit. It is perfectly suited to fuller figures, as its length visually elongates the silhouette.

It is also the preferred length for pendant necklaces, such as photo projection necklaces: the pendant falls to mid-chest, right where it is best seen and where it is easy to tilt the jewelry slightly to reveal the photo hidden inside.

The opera necklace (70 to 90 cm)

The opera necklace is a long necklace that falls below the bust. It can be worn in a single strand for a bohemian or chic effect depending on the materials, or doubled to create a trendy layered effect. It is a bold length, worn more often for evenings out or with dressed-up outfits.

The sautoir necklace (more than 90 cm)

The sautoir is the longest length. It can be worn simple, doubled, or even knotted. It is a piece with character, often worn alone to structure a minimalist outfit or, conversely, layered with other shorter necklaces for a bold layering effect.

How to measure your neck size correctly?

Before ordering a necklace, especially if you are considering a choker or princess length, it is useful to know your neck size. The method is simple:

Take a flexible measuring tape (or, failing that, a string that you then measure with a ruler) and place it around your neck where you want the necklace to rest. Note the measurement obtained, then add 2 to 5 cm depending on the desired comfort.

Practical example: if your neck size is 35 cm and you want a comfortable choker, a chain of 38 to 40 cm with an adjustable extension system will be ideal.

Most of our necklaces even incorporate a small extension ring at the end of the chain, precisely to let you adjust the length by 2 to 3 cm according to your preference of the moment.

Which length to choose based on your body type?

This is arguably the most important question. The right length is not just a matter of personal taste; it also depends on your silhouette.

For a short or wide neck

Avoid necklaces that are too short, as they visually accentuate the width of the neck. Opt for matinee (50-60 cm) or longer lengths, which elongate the line and clear the neckline. A necklace with a drop-shaped or V-shaped pendant is particularly flattering in this case.

For a long and slender neck

All lengths suit you, you are in luck! The choker will be particularly enhanced on a long neck. The princess necklace will flatter your collarbones. You can also afford to layer, stacking two or three necklaces of different lengths, for a result that is always elegant.

For a slim and slender silhouette

Short necklaces will highlight your bone structure. The choker and the princess necklace are your best allies. Avoid very long sautoirs, which risk unbalancing your silhouette.

For a round and generous silhouette

Matinee and opera lengths are your friends. They create a vertical line that visually elongates the silhouette. A diamond or arrow-shaped pendant accentuates this effect. Avoid short, thick necklaces that widen the neckline.

Which length according to the type of clothing?

The ideal length also depends on what you are wearing. Here are some pairings to remember:

Round neck or crew neck: choose a necklace slightly longer than the neckline, starting from 45-50 cm, so that it is visible and does not blend into the fabric.

V-neck or décolleté: the princess necklace (42-45 cm) is perfect because it naturally follows the line of the neckline. A pendant matinee necklace also creates a very beautiful effect with a V-neck.

Collared shirt or button-down blouse: a choker visible above the collar adds a touch of elegance and personality. It is the perfect opportunity to show off a subtle but noticeable initial necklace.

Evening dress or dressed-up outfit: treat yourself to an opera necklace or an elegant pendant on a matinee chain. The jewelry then becomes the centerpiece of your look.

Necklace length for children and teenagers

If you are looking for a necklace as a gift for a child or young teenager, standard adult lengths are often too large. Here are the usual benchmarks:

• Child (6-10 years): 35 to 38 cm
• Preteen (10-14 years): 38 to 42 cm
• Teenager (14-17 years): 40 to 45 cm, like an adult with smaller measurements

If you want to give a name necklace to a child, for example, opt for a chain with an adjustable extension so that it can accompany their growth for several years.

How to choose the length when giving a necklace as a gift?

This is often the number one puzzle: you want to give a personalized piece of jewelry but you are not sure about the size. Here are some proven strategies.

Go for the classic. The 42-45 cm length (princess) is the safest choice for an adult woman. It is suitable for 90% of body types and occasions.

Observe the jewelry she already wears. If the person usually wears her necklaces at mid-collarbone, a princess length is perfect. If she wears them lower, go for 50 cm.

Choose a chain with an extension. Most of our models offer 2 to 3 cm of additional extension, which leaves a comfortable margin.

Ask (subtly). You can also slip the question into a casual conversation: "Do you prefer short or long necklaces?" The answer will guide you enough without raising suspicions.

Finally, if you are hesitating between two lengths, know that our customer service is available 6 days a week to advise you on the model that will best suit the person you wish to please.

Necklace length and material: are they linked?

Not directly, but there is a logic to know. Necklaces with thin chains (gold, silver, steel) handle all lengths well. However, necklaces with large links or bulky beads are more advantageous in short or medium lengths; beyond that, their weight can become uncomfortable after a day of wear.

Layering necklaces: how to choose the right lengths?

Layering, the art of stacking several necklaces, is a strong trend that shows no signs of slowing down. For a harmonious result, a few simple rules:

Maintain length differences of at least 5 to 8 cm between each necklace. If you wear a choker at 38 cm, the next one should be at least 43-45 cm, and the third 50-55 cm.

Vary the styles but remain consistent in the finishes. A matte gold necklace with a shiny gold necklace is very beautiful. A gold necklace with a silver necklace is possible if it is intentional, but riskier visually.

Start simple. Two well-chosen necklaces are better than four that get tangled. A choker with a mid-collarbone pendant is already a very elegant result.
